Buffer capacity based node life time estimation in wireless sensor network

Lifetime improvement is the mandatory part of Wireless Sensor Network. The lifetime of the node is majorly influenced by the data sent, distance between nodes and residual energy of the node. The number of data transmitted cannot be limited; however the number of transmitter on and off energy dissipation could be minimized. The data transition cost and holding cost is derived with respect to data arrival rate. This article analysis the energy of dissipation of the node with respect to different arrival rate and buffer threshold value. The analysis is carried for different distance and different arrival rate. The data arrival rate to the node is considered as poisson in nature. The results prove that the threshold based model provides considerable amount of energy savage to the node, thereby can able to increase the network lifetime.
