Abstract

Objectives: The main objectives of this research are to improve performance of LEACH protocol for data gathering by deploying multiple sinks. The movement of the sinks are depends upon the signal strength and bee colony algorithm. By using the proposed technique performance of LEACH protocol is increased. Method Analysis: To improve performance of LEACH protocol is improved by deploying multiple sinks and movement of the sinks are decided using bee colony. Findings: By Appling bee colony with LEACH protocol for multiple sink movement various energy parameters are analyzed and compared with existing algorithm. It is seen that energy consumption of the network reduced and network is increased. The improvement leads to batter data gathering from cluster heads and throughput of the network is increased.

Abstract

Wireless Sensor Networks finds it difficult to transfer equal amount of data through all nodes, and in minimizing the level of energy consumption during transmission of data. This paper is an improvement to LEACH protocol; suggested to increase the overall lifespan of the network. Formation of clusters is based upon distance of nodes from base station, number of neighbor nodes and distance among neighbor nodes. The cluster heads are selected on the basis of nodes holding maximum energy. We have proposed the concept of selecting the master cluster head from the elected cluster heads based on the strength of energy that CH nodes have and the distance from the Base station. Further, using this concept, the fused data from master CH are forwarded to the sink node. Proposed work reduces the frequency and length of data exchanged between the CHs and the Base station. Simulation results revealed that the proposed method reduces the consumption of energy by 46.85 percent and increases the lifespan of the network efficiently. The parameters for comparison are First Node Dead and Half Node Alive.
