Dynamic resource management using gesture-based user interface

We propose and implement a user-convenient method for dynamically utilizing resources across varying platform devices using air gesture-based user interface. Resource-sharing is the most ubiquitous task found in modern days. Most commonly used methods includes usage of bluetooth, pen drives, external hard disks, emails, chat applications and social networking websites for sharing images, video/audio resources, url and other contents. The proposed idea eliminates the elaborate process of choosing the resources to be shared and also selecting the method of transfer, be it any of the ways mentioned above. Our idea encapsulates the entire process into a single gesture for the resource-sharing mechanism. In this work we put forward a user friendly, intuitive approach for sharing of resources among cross-platform computing devices using ip network as a medium of transfer and human hand gestures as user interface conjugated with dynamic detection and rendering of the resource.

A New Approach for Analyzing the Performance of the WiMAX Networks based on QoS Traffic Prediction Routing Protocol using Gene Expression Programming

WiMAX is one of the broadband wireless access technologies, which provides the efficient QoS to the large number of users. The multimedia applications such as real time and non-real time services are gaining importance in the WiMAX network. To support such applications, there is a need to propose an efficient QoS traffic prediction routing protocol for the WiMAX networks. To address this, the authors are using Gene Expression Programming technique. They have generated datasets for CBR based traffic and file transfer applications. Here, they focus to develop the mathematical expressions for throughput of the network in terms of bandwidth, average end-to-end delay and average jitter for CBR based traffic and file transfer applications, so that they can analyze and predict the QoS traffic of the network. The simulation results show that the model values and the target values match with better approximation. Further, sensitivity analysis has been carried out for both CBR based traffic and file transfer applications.

An analysis and comparison of different routing algorithms in WiMAX networks

World-wide interoperability for Microwave Access (WiMAX) is a wireless metropolitan area networks (WMANs). Routing and multimedia application plays an important role in the WiMAX networks. In this study, the main focus is on analyzing and comparing the different routing algorithms such as AODV, DYMO, DSR, Bellman-Ford and Fish-Eye for the WiMAX networks. We have considered few QoS parameters such as total data received, average end-to-end delay, average jitter and throughput. Here, we have considered the CBR application. From the obtained result DSR routing algorithm outperforms high throughput and total data received. Bellman-Ford and Fish-Eye provides less average end-to-end delay. Bellman-Ford routing algorithm also provides less average jitter.

Network management and performance monitoring using Software Defined Networks

Nowadays Computer Networks are in constant evolution. New methodologies and techniques are required to manage the network. Software Defined Network (SDN) is a new approach to manage and maintain the network infrastructure. Mininet is the most popular emulator to understand and experience how SDN works. Our proposed research addresses the following problems. i) Enhance default version of Mininet to create the custom topologies in a user friendly manner without explicitly writing any programs. The users/researchers can even specify the different link parameters like Bandwidth, Latency etc. through a simple text file and create the network topology of their choice to test their innovative ideas and protocols. ii) Our next focus is to collect the information from the SDN controller, preserve it for historical analysis and present via a web interface. iii) Use SDN to reduce the Layer-2 broadcast traffic in Data Centres. This is being achieved by making use of hierarchical switch connectivity with pseudo MAC addresses. iv) Our last focus is the introduction of Cross Layer Optimization algorithms for better resource utilization in Data Centres. These new techniques help the network administrator and the end user to experience better application and network performance.

Location area planning problem in WiMAX networks using nature inspired techniques: performance study

Worldwide Interoperability for Microwave Access (WiMAX) is a broadband wireless technology that provides an efficient service to mobile stations (MS). Whenever there is a need to establish communication and provide service to MSs, the network has to track the location of the MSs through the base station. Tracking the location of the MSs is a very difficult and complex problem in the WiMAX network. This paper discusses a location area planning problem, which can be solved by partitioning the WiMAX network into location areas, so that the cost per call arrival is minimum. Finding the optimal number of location areas and the corresponding configuration of the partitioned network is an NP-complete problem. In this study, we use nature inspired techniques, namely, genetic algorithm (GA), artificial bee colony (ABC) and artificial immune system (AIS) to find an optimal solution to the location area planning problem. The performance is analysed and compared for all these nature inspired techniques. In this study, we also compare these techniques to gauge their suitability for solving the location area planning problem. From the obtained results, we conclude that ABC gives better optimal solution and AIS takes less computational time to locate the optimal solution.

Zygote: A Framework for Prototyping Smart Devices

The Internet of Things (IoT), which has had an unprecedented effect in the manufacturing industry, is now becoming increasingly popular in everyday life. Even with the rising interest in IoT among developers, there is no simple way for them to prototype and realize their ideas. As of today, developing an IoT project requires cross domain knowledge of hardware, embedded systems, communication protocols, and cloud and web technologies. We propose and implement the Zygote framework, a browser-based tool to lower the entry barrier and enable rapid prototyping and building of IoT projects. Zygote reduces the time and effort required to do so by providing a visual interface to configure, control and deploy an IoT application. It also exposes a REST API for programmatic control as well as a dashboard for quick data visualization. With its modular architecture, it supports the creation of custom plugins as required by the developer. The Zygote framework enables users to build IoT prototypes in minutes and with virtually zero lines of code.

A framework for efficient placement of relay station and routing in IEEE 802.16j MMR network

We have studied the problem of cost per call arrival from the following two perspectives in WiMAX network: Location Management Problem and Placement of Relay Station Problem. In location management problem, we investigated the application of nature inspired techniques like GA, ABC and AIS for an optimization of cost per call arrival in WiMAX networks. Result obtained from all these nature inspired techniques are compared and analysed. In all these nature inspired techniques, performance depends on the population size. Results of the experiments show that GA, ABC and AIS can be effectively implemented for location management scheme. ABC show better performance in terms of optimal value of cost per call arrival and AIS takes less computational time to locate the optimal solution in the network.

Cross stratum optimization algorithms for network and application resources

Different applications are offered by data centres like Video gaming, VoIP, HD-video Streaming, Remote medical surgery etc. These data centres are placed in different locations and connected by the underlying network infrastructure. One data centre may offer several services or same service may be offered by several data centers. Currently data centres offer services without considering the load on the network The goal of our proposed work is to provision the services to the users by considering the application needs as well as the network status. Different categories of users require different services over the shared network Idea of this work is to satisfy all the categories of user needs by optimizing the network resources and application resources.
