MERCC: Multiple Events Routing with Congestion Control for WSN

Wireless sensor networks consisting of many small sensor nodes with limited power resources, are useful in gathering data in different environment. Some of the algorithms focus on setting up an event path and the nodes get the information by sending the queries to the event path. On the other hand some algorithms flood the event information from source node to its neighbors and from neighbors to the neighbors of neighbors and so on. The first type involves extra delay, and the second type consumes more power. In this paper we introduce a new protocol ‘MERCC’ which can handle multiple events at a single instance with power effective methodology. MERCC tries to retain the performance even in case of network congestion.

Intelligent Energy Efficient Routing for Ad-Hoc Sensor Network by Designing QCS Protocol

In today’s world Wireless Ad-hoc sensor network, which consists of many small sensor nodes having limited resources, has a great potential to solve problems in various domain like disaster management, military field etc. In this paper a new protocol “QCS-protocol” has been introduced which is the backbone of our Intelligent Energy Efficient Ad-hoc Sensor Network. Two other protocols “Final Broadcast-Petrol Flow” protocol and “Irregular Information Transfer” protocol are designed to help the QCS protocol to run the system properly and make the network more energy efficient and perfect. The challenges in Ad-hoc sensor network are limited node power, Ad-hoc organization of network and reliability. Most of the existing approaches have done by addressing the problems separately, but not in a totality. This paper shows how the network can have unlimited life and all time readiness with overall stability to send information to the base station with minimum power dissipation with the help of multimode same type sensor nodes and type categorization of generated information.

Secure energy efficient routing protocol for wireless sensor network

Abstract The ease of deployment of economic sensor networks has always been a boon to disaster management applications. However, their vulnerability to a number of security threats makes communication a challenging task. This paper proposes a new routing technique to prevent from both external threats and internal threats like hello flooding, eavesdropping and wormhole attack. In this approach one way hash chain is used to reduce the energy drainage. Level based event driven clustering also helps to save energy. The simulation results show that the proposed scheme extends network lifetime even when the cluster based wireless sensor network is under attack.

A Study on Routing Protocols in Wireless Sensor Network

Wireless Sensor Network (WSN) consists of many small sensor nodes. A sensor node is a battery operated small device capable of computation and communication. These nodes are capable of sensing events within their coverage area. The main objective of WSN is to sense destructive events from its environment and send that information to the sink node, so that it can take the corrective actions. As the sensor nodes are deployed in remote location, it is very difficult to recharge the batteries. Thus energy efficiency is the main challenge in WSN. The paper gives a brief study about different energy efficient routing protocols, so that the problem areas can be identified and solved.

Secure Hierarchical Routing Protocol (SHRP) for Wireless Sensor Network

Wireless Sensor Network (WSN) has emerged as an important supplement to the modern wireless communication systems due to its wide range of applications. The communication of sensitive data and working in hostile environmental condition needs security. The energy constraints, limited computational ability and low storage capacity of the sensor nodes have made the implementation of security more challenging. The proposed scheme adopts a level based secure hierarchical approach to maintain the energy efficiency. It incorporates light-weight security mechanisms like, nested hash based message authentication codes (HMAC), Elliptic-Curve Diffie-Hellman (ECDH) key exchange scheme and Blowfish symmetric cipher. Simulation results show that the scheme performs better than existing secure routing protocols FBSR and ATSR.

Energy efficient cluster based routing protocol (EECBRP) for Wireless Sensor Network

Wireless sensor network consists of micro electro-mechanical sensor nodes which are operated by battery power. Sensor nodes lose energy for computation and communication. It is very difficult to recharge their battery as they are deployed in a remote place. Thus, power efficient routing in wireless sensor network is the main challenge for researchers. Hierarchical routing is one of the efficient techniques for routing the sensed data from source node to the base station. The proposed algorithm (EECBRP) deals with cluster formation based on different events, cluster head selection, aggregation of the sensed data within a cluster and sending that to the base station in an energy efficient way. Simulation result proves that the proposed protocol (EECBRP) performs more efficiently than Energy Efficient Heterogeneous Clustered Scheme for Wireless Sensor Network (EEHC) and Smart Cluster Head Selection Scheme for Clustering Algorithms in Wireless Sensor Networks (SCHS).

Multiple Event Source Routing (MESR) for Energy Efficient Wireless Sensor Network

The Wireless Sensor Network (WSN) is used to sense different events occurring at different sections of the remote network. The sensor nodes have limited battery power, and the nature of their deployment makes recharging almost impossible. To limit the power drain, efficient communication protocols are needed. This paper proposes Multiple Event Source Routing (MESR) for sending critical information by optimal path, so that it reaches the base station in shortest possible time. MESR sends regular or not-so-critical information in one of the multiple routing paths. MESR is capable of handling multiple events simultaneously. It defines an overhearing ratio in order to reduce an overhearing energy waste among selected paths. Thus MESR protocol improves reliability as well as network lifetime also.

A Novel Power-Balanced Routing Scheme for WSN

Wireless sensor networks consist of hundreds or thousands of small sensors with have limited resources. The energy resource is the most challenging one to be maintained. The major reason for power drain is the communication between sensor nodes. Most of the routing algorithms for sensor networks focus on finding energy efficient paths to prolong the lifetime of the networks. In this paper, a novel routing algorithm has been proposed to detect the source of an event in the network. This algorithm also maintains a balance between the powers of different nodes in the network, so that the longevity of the overall network may increase.

Classification-Based Clustering Approach with Localized Sensor Nodes in Heterogeneous WSN (CCL)

In wireless sensor network, random and dense deployment of sensor nodes results in difficulties for sink node to detect the location of them without GPS. The inclusion of GPS for all sensor nodes increases the deployment cost. Energy is another constraint in wireless sensor network during data forwarding. In this paper, the proposed protocol CCL has applied the modified version of DV-hop technique to detect the location of sensor nodes without using GPS. Here, event-based clustering is designed to save the energy of nodes, which is classified using support vector machine. Packet is forwarded to the sink node by greedy forwarding technique. Packet loss is also removed by involving an antivoid approach called twin rolling ball technique. Simulation results show that the performance of CCL is enhanced with compared to LEACH, HEED, EEHC, DV-hop, and advanced DV-hop.
