An Adaptive Energy Aware Clustering Based Reliable Routing for in-Network Aggregation in Wireless Sensor Network

Abstract

Wireless Sensor Network (WSN) consists of spatially distributed autonomous devices that cooperatively sense physical or environmental conditions. Due to the non-uniform node deployment, the energy consumption among nodes are more imbalanced in cluster-based wireless sensor networks this factor will affect the network life time. Cluster-based routing and EADC algorithm through an efficient energy aware clustering algorithm is employed to avoid imbalance network distribution. Our proposed protocol EADC aims at minimizing the overall network overhead and energy expenditure associated with the multi hop data retrieval process while also ensuring balanced energy consumption among SNs and prolonged network life time .A optimal one-hop based selective node in building cluster structures consisted of member nodes that route their measured data to their assigned cluster head is identified to ensure efficient communication. The proposed routing algorithm increases forwarding tasks of the nodes in scarcely covered areas by forcing cluster heads to choose nodes with higher energy and fewer member nodes and finally, achieves imbalanced among cluster head and improve the network life time.
