Abstract

Sensor nodes are used to measure ambient of environment. Sensor network can be defined as a collection of sensor nodes, which senses the environment and sends information to the base station. These types of networks are facing problems related to energy dissemination. LEACH (Low Energy Adaptive Cluster Hierarchy) protocol is one of the most suitable protocols used for communication in a sensor network. LEACH protocol is a cluster-based protocol, in which each cluster consists of multiple nodes and one cluster head node. The cluster head aggregates all the information from other nodes in the cluster and conveys it to the base station. In LEACH protocol, cluster head selection is performed in each round at the cost of some amount of energy. In our proposed solution, the energy consumption for electing cluster head in every round is circumvent. This can be achieved by threshold value-based cluster formation. The proposed method reduces the overhead of forming cluster in every round, which helps in reduction of energy consumption. As a result of the work, the performance of proposed solution is compared among a variety of LEACH protocols with respect to lifetime of the network.
