This paper present a hybrid approach to improving the network lifetime and coverage/connectivity of wireless sensor network. Here we apply a new deployment scheme with GA based routing to improve network lifetime and coverage. G A based clustering on routing is used in this paper to select the path for data transfer in such a way that total energy consumption along the path is minimized. Coverage is another important factor in wireless sensor network. The position of sensor nodes must also be provide maximum coverage. In this paper, we also introduce a zonal approach for deployment which provide maximum coverage. Experiments shows the accuracy of genetic algorithm is better than LEACH, and provide better energy efficiency or improv e network lifetime. The simulation result also shows the uniform placement of sensor nodes provide better coverage and connectivity as compare to random placement of sensor nodes.
