Wireless sensor networks are networks of large number of tiny, battery powered sensor nodes having limited on-board storage, processing, and radio capabilities. Nodes sense and send their reports toward a processing center which is called sink or base station. Since this transmission and reception process consumes lots of energy as compare to data processing, designing protocols and applications for such networks has to be energy aware in order to prolong the lifetime of the network. Generally, real life applications deal with heterogeneity rather than homogeneity. In this paper, a protocol is proposed, which is heterogeneous in energy.
