A MOBILE AGENT BASED INTRUSION DETECTION SYSTEM ARCHITECTURE FOR MOBILE AD HOC NETWORKS

Applications of Mobile Ad Hoc Networks (MANETs) have become extensively popular over the years among the researchers. However, the dynamic nature of MANETs imposes a set of challenges to its efficient implementation in practice. One of such c hallenges represents intrusion detection and prevention procedures that are intended to provide secured performance of ad hoc applications. In this study, we introduce a mobile agent based intrusion detection and prevention architecture for a clustered MANET. Here, a mobile agent resides in each cluster of the ad hoc network and each cluster runs a specific application at any point of time. T his application specific approach makes the network more robust to external intrusions directed at the nodes in an ad hoc network.

A Multi-agent-Based Framework for Cloud Service Description and Discovery Using Ontology

The spectrum of cloud service providers has become large these days with increasing popularity of cloud computing as a service. These services appear to be similar in their approaches excepting that they vary in their key attributes such as price, computational power, and storage policy. As of now, there are no standardized specifications defined for a cloud service provider. Different cloud service providers use different vocabulary to specify similar operations. A number of quality of service (QoS) parameters may be associated with a service, and thus, identification of the appropriate parameter and its management is the vital issue that needs to be addressed by the service provider. In this context, the search engines such as Google, MSN, etc., do not represent the most effective and most efficient tools in order for determining the appropriate cloud service that could optimally meet the service requirements of a customer. It remains as a challenging issue for a customer requesting for a cloud service. Thus, there arises the necessity of a reasoning mechanism for service discovery that is capable of resolving the similarities among variety of services. In this paper, we address a semantic-based service description and discovery framework using multi-agent approach, where the cloud service descriptions that are automated based on shared ontology, contribute to optimal discovery of appropriate services as requested by consumers.

A methodical survey on real time applications in MANETS: Focussing on key issues

There are many important real-time applications like multimedia services, recovery problems from disasters etc which can be successful only if Quality-of-Service (QoS) can be provided for MANETs. But providing QoS in MANETs is really a tedious task specially in real time category. In this paper an analytical survey has been done on various directions and factors affecting the performance of applications of real time type in MANETs, their proposed solutions to improve their performance. We are also doing an analytical survey on real time events classification and their solutions.

Energy Competent Routing Protocol Design in MANET with Real Time Application Provision

With the increase of mobile activities in technological environment, it is a challenge to develop and maintain robust networking system with provision of high connectivity. In this context, Mobile Adhoc Network MANET is a feasible solution because it is dynamic in nature and the self-configured nodes of MANET can communicate intelligently in adverse and dynamic mobile situations. Though Adhoc on Demand Distance Vector AODV Routing protocol handles the networking issues efficiently, still power and delay efficiency has always been a challenging task in MANET due to the resource constrained nodes which are supplied with limited battery power during the operation in the network. Hence while performing various networking activities; gradually the battery power reduces resulting in delay in processing of packet and forwarding them to the next node during transmission. This causes overall end to end delay in the total transmission. Therefore many researches are still going on in the direction of designing robust and reliable protocols. In this paper the authors have developed a robust and energy efficient routing protocol for MANET with real time support. Their approach is different as it calculates the remaining residual battery power, bounded delay and packet processing rate of the intermediate node before selecting a node to forward the packet in the direction of destination. The cost function calculated using the above three factors along with the condition of congested node is also checked to correctly choose a load balanced path from source to destination. Simulation results show that the proposed protocol performs better than the conventional AODV protocol in terms of better network life time, throughput, delay and packet delivery ratio.

An Optimized Cluster Based Routing Technique in VANET for Next Generation Network

Since last few years, research in the field of vehicular networking has gained much attention and popularity among the industries and academia. Intelligent approach for such technology is the challenge. In this paper, we have taken an attempt to optimize the routing algorithm for vehicular adhoc networking (VANET). Ant Colony Optimization (ACO) is an optimization technique and is applied based on clustering technique. To improve the safety factor and efficiency and to develop an intelligent transport system, it is highly conceptual with the wireless technology. It is a special type of MANET, because of the variation of routing protocols. Even if the protocols of MANET are feasible, they are not able to provide the optimum throughput required for a fast changing vehicular ad hoc network. Positions of the vehicles create the zone and the optimization is zone based. Ant Colony algorithm is combined with zone based clustering algorithm to improve the result. This approach combines the advantages of both the techniques, the ant colony algorithm as well as the zone based routing algorithm. Routing overhead has been compared between AODV, MARDYMO and TACR protocols and depicted in the graphical plots.

Cross layer based QoS platform for multimedia transmission in MANET

Transportable nodes in a healthy and demanding network set-up of Mobile Adhoc Network (MANET) are self-governing with self-configurable potential due to high occurrence of topology alteration and changeable rescheduling of the network mechanism during data communication. Due to simplicity of set up, the energetic networking system in MANET is very victorious in conditions where it is complicated to create communications system and infrastructure based network. Numerous routing protocols for MANETs accompanying real time applications have been developed, basic intention being optimal consumption of resource in resource limited situation, least power utilization using limited battery power of the highly short-lived mobile nodes and victorious real time data broadcast within their deadline. This paper presents an efficient Quality of Service architecture using inter layer communication with a highly efficient real time scheduler design at the network layer with improved RMA (Rate Monotonic Algorithm) and EDF(Earliest Deadline First) scheduling that efficiently schedules multiple real time applications without missing any of their deadline. Simulation results in NetSim ver 8 ensures healthier network performance in terms of better jitter, packet delivery ratio and network lifetime when compared with other similar Cross layer based approaches for video file transmission.

Load balanced routing scheme for MANETs with power and delay optimisation

Innovative research on mobile ad hoc networks (MANETs) and their wide applications have created a revolution of todays wireless communication. Efficient routing for dynamically changing network and unstable wireless medium is a challenging task. The conventional AODV routing protocol works on selecting the hop count-based shortest path while delivering the packet towards the destination. This often creates uneven load distribution among network nodes. As a result, any central node hopelessly carries heavier loads that significantly deplete node energy with higher packet loss and delay in processing. In this work, a protocol based on power and delay named as power and delay optimised AODV (PDO-AODV) has been presented which is based on load balanced routing strategy in AODV that improves the quality of service for MANETs. The proposed approach takes neighbouring nodes power and delay into consideration for selecting load balanced path. Simulation results manifest that the proposed PDO-AODV achieves improved performance as compared to existing AODV routing protocol in terms of packet drop, network delay, throughput, and retransmission attempts.

MAQ: A Mobile Agent Based Quality of Service Platform for MANETs

Protected data transmission in cluster based Mobile Adhoc Networks (MANETs) is a challenging mission due to the high level of node mobility of nodes and resource constrained autonomous stations during packet routing. To target this mission, a Mobile Agent based QoS (MAQ) platform has been planned in this paper that uses an improved clustering algorithm during data communication. A Mobile agent architecture has been anticipated in a way that it is coupled with the cluster head of every cluster in MANET and when priority based real time application gets notified in these clusters then the proposed system gets activated to support prioritized service to these applications including checking and monitoring the flow characteristics for real time applications. JADE (Java Agent Development Environment) based prioritized scheme at the mobile agent has been implemented in the proposed system. As this is a function oriented approach, so the overall network performance significantly improves resulting better throughput and packet delivery ratio.

Service Composition Using Efficient Multi-agents in Cloud Computing Environment

In today’s Internet world, end users need everything as a service (EaaS) being available to them throughout the world. Keeping users in the centre, developers are emplaning cloud computing environment which can satisfy needs of users virtually. Cloud computing is a collection of Web-accessible resources (i.e. Web services) that should be dynamically composed between service providers and brokers and virtualized based on consumer’s needs on an on-demand basis. Mapping of the users’ requirements should be done in an automated manner. But, distributed and constantly changing cloud computing environments pose new challenges to automated service composition such as: (i) dealing with incomplete information regarding cloud resources (e.g. location and providers), and (ii) dynamics of service providers, which set service fees on a supply-and-demand basis. To address these issues, we have proposed a multi-agent-based approach to compose services in multi-cloud environments for different types of cloud services: one-time virtualized services, persistent virtualized services, vertical services, and horizontal services. Cloud participants and resources are implemented and instantiated by agents. Previously the researchers have proposed self-organizing agents those make use of Service Capability Table and the semi-recursive contract net protocol (SR-CNP) to evolve and adapt cloud service compositions. To the existing work, we have planned to modify some of agents’ behaviours, as a result we can reduce number of message passing by half in order to increase overall performance. Also we are planning a 2-layered (3 levels of multi-agents) self-organizing MAS that will establish a cloud service composition.

Monitoring of QoS in MANET Based Real Time Applications

Specialty of Mobile Adhoc Networks (MANET) is that in current mobile technology it is the most promising and highly developed elucidation due to its remarkable performance in offering network connectivity even in very radical situations of adversity where there is maximum chance of link failure and more necessity of quick set up of networks. The elemental routing procedure in a MANET involves facilitating unremitting communication in the network system between two mobile stations during required period of time and the basic factor being selection of the most suitable forwarding node to proceed the real time packets from source towards destination in such a way that the optimization of the network can be achieved by maximum utilization of available resources. Considering that real time applications are one of the most challenging issue in MANET, due to transportation of high volume of data including audio, video, images, animation and graphics, this paper presents a monitoring approach for checking the Quality of Service (QoS) conditions during competent routing using the concept of Mobile Agents. An intelligent mobile agent is designed in the proposed QoS platform that monitors and controls the QoS processing tasks using longest critical path method at the forwarding node to select it as the best option out of all neighbor nodes. Simulation results shows higher packet delivery ratio and comparatively reduced bandwidth consumption overhead when it is compared with other similar approaches.
