Wireless Sensor Network’s lifetime depends on the energy levels of individual nodes in the network. The energy usage depends on the MAC and routing protocols, topology, and transmission policy. Thetransmission policies in WSN as of now cause irregular usage of energy and it results in the reduction of energy levels of nodes in the network. Gradually it leads to the reduction of lifetime of the network. This paper presents a new method to overcome this problem. It divides the transmission distance into two parts based on the concentric rings which are formed around the sink as part of transmission mechanisms in WSN. The two parts are namely ring thickness and hop size. Here we consider the network lifetime as a kind of optimization problem. To achieve this we analyze the energy consumption in the transmission process and decide the optimal hop size and ring thickness. The empirical results revealed that through our energy balanced transmission policies, the network lifetime is increased substantially.
