ABSTRACT
A wireless sensor network is composed of hundreds or thousands of nodes that are densely deployed in a large geographical area. And these sensor nodes are small, wireless and battery powered. Routing is often a challenge and difficult problem because various factors like limited energy of sensor nodes, unreliable communication channels i.e. harsh environment, battery depletion etc are to be considered. There are various routing protocols that can be broken down based on some techniques. According to network structure it can be classified as flat, hierarchical or location based. In this paper, we propose an energy efficient and reliable routing protocol (EERR), which uses hierarchical clustering and to develop it we introduce a set of cluster heads and headset in which two phases namely election phase and data transfer phase are considered. During the election phase a head-set consisting of several nodes is selected and in the data transfer phase the headset member receives data from the neighboring nodes and transmits the aggregated results to the distant base station, which is done on a rotation basis. The results show that the energy consumption can be decreased and the lifetime of the network is also increased.
