Transmission range management for lifetime maximization in wireless sensor network

In the sensor network the nodes which are nearer to the base station (BS) have additional communication loads of forwarding data generated by distant nodes. Thus they lose their energy rapidly and die soon where as distant nodes remain alive. It creates a bottleneck of communication after sometime for alive nodes. We propose here that distance between two successive nodes around BS should be lesser than the same of peripheral nodes. Thus nodes around BS will have to transmit to lesser distance and hence low power consumption per bit of transmission can be ensured. This will prevent these nodes from dying sooner and this bottleneck can be avoided.
