In the lifespan of the sensor network, coverage, localization, reliability and lifetime (when the final sensor dies) are the major design challenges for which the work is still going on. Especially in heterogeneous wireless sensor network, it is very difficult to estimate the coverage and lifetime of the network. There have been many existing classical protocols in heterogeneous network where the heterogeneity was taken either in sensing radius or in the energies of nodes. An idea to increase the coverage ratio as well as the lifetime of the senor network is suggested in this paper by introducing mobility in heterogeneous WSN, where the heterogeneity is considered in energy of nodes. We have chosen the deployment in heterogeneous wireless sensor network with loco-mobility capability nodes which has different energies. The simulation results show that in our algorithm, maximum area is covered, and in addition, some nodes are in off state to conserve the energy. We consider the nodes to cover large area while being reliable in sensing by saving energy. Our proposed algorithm’s target is to schedule the sensor nodes in such a way that they can monitor a region efficiently. We compare our scheme with already existing protocol named as stable election protocol, analyzing the network lifetime for different number of nodes in various areas and also the coverage throughout the lifetime.
