Abstract

Wireless sensor networks are challenging technology regarding communication because of its limited resource nature and various network topologies. Wireless Sensor Network is to minimize energy consumption by each sensor node and increase network communication lifetime. This paper using a modified algorithm for Low Energy Adaptive Clustering Hierarchy protocol. The movement of mobile nodes is decided on the basis of their distance from CHs. These papers analyze the several clustering techniques with Modified LEACH concept.

Introduction

There are different communication technologies developed in networking system, for computation, data gathering, and automatic information collection. The sensor networks have a large number of sensor nodes (SN). These sensor nodes are massively deployed in a region of interest to collect information from their surroundings. After collecting the information the sensor node do some computation on that data and send it to the sink for further processing. Data transmission from note to note and note to sink should be reliable. The data is forwarded, possibly via multiple hops relaying, to a sink that can use it locally, or connected to other networks figure 1 shows the data communication for WSN.

Conclusion

The performance of wireless sensor network has been performed to obtain the energy consumption and reliability. In this paper, we propose a modified algorithm for Low Energy Adaptive Clustering Hierarchy is an efficient technique. These parameter of WSN depends on the hop distance and update time of network. The proposed protocol shows the better improvement over existing protocol.
