A LEACH Protocol for Design a Clustered Head Selection Approach in Wireless Sensor Networks

Poonam Sharma, Sunita Parashar


In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy-efficient routing protocol and enhancing nodes’ lifetime from routing’s aspect. LEACH includes the distributed cluster formation, local processing to reduce global communication, and randomized rotation of the cluster-heads. A wireless sensor network consists of hundreds or thousands of small energy-limited sensors that are densely deployed in a large geographical region. It has been demonstrated that Low-Energy Adaptive Clustering Hierarchy (LEACH) is an energy-efficient routing algorithm for Wireless Sensor Networks (WSN). In this paper, we present a cluster head selection approach for LEACH. We state the principles of the LEACH and give the main flowchart and pseudo codes realizing LEACH. We improves the choice method of the cluster head, makes some nodes which have more residual energy as cluster heads in next round.
