ABSTRACT
A wireless sensor network with a large number of tiny sensornodes can be used as an effective tool for gathering data forvarious applications under different situations. One of themajor issues in wireless sensor network is developing anenergy–efficient routing protocol which has a significantimpact on the overall lifetime of the sensor network. Clusteringsensor nodes is an effective technique in wireless sensornetworks which can increase network energy efficiency,scalability and lifetime. In this paper, we have proposed anenergy–efficient clustering based protocol for wireless sensornetworks. We have considered a set of cluster heads for controland management of the network. On rotation basis, a clusterhead receives data from the neighboring nodes and transmitsthe aggregated data to the base station. Adopting thisapproach, Energy Efficient Clustering Hierarchy and DataAccumulation (EECHDA) is better than existing protocols interms of energy consumption and network lifetime. Oursimulation results demonstrated that EECHDA is able toprolong the time interval of the death of first node in thenetwork.
