Optimization of Energy Efficient Hierarchical Routing Protocol in Sensor Network

Abstract

Wireless sensor networks (WSNs) have gained increasing attention from both the research community and actual users. In the wireless sensor networks (WSNs), the sensor nodes (called motes) are usually scattered in a sensor eld - an area in which the sensor nodes are deployed. These motes are small in size and have limited pro- cessing power, memory and battery life. The motes in these networks are coordinated to produce high-quality information and each of these scattered motes has the capa- bilities to collect and route data back to the base stations, which are xed or mobile. As sensor nodes are generally battery-powered devices, the critical aspects to face concern how to reduce the energy consumption of nodes, so that the network lifetime can be extended to reasonable times. I concentrated on optimization of Hierarchical Energy Efficient Routing Protocols. Since unstable and unevenly distributed cluster heads can increase power of the network system in some existing protocol. I have proposed new technique for cluster head selection and cluster formation so it selects the consistent cluster heads in each round, also form the balance clusters in the existing hierarchical routing protocol(LEACH) to reduce the energy consumption of sensor nodes in sensing, processing and communication activities, overall it increases the lifetime of network.
