Power Consumption and Maximizing Network Lifetime During Communication of Sensor Node in WSN

Abstract

The recent advances and development of wireless sensor network is dependent on low-cost, low-power and multifunctional sensor nodes. Sensor Networks are very much data concentric and it is totally depends on the activities of the sensor node. The natural job of sensor node in a network are sensing the network, processing the data and broadcast the communication to other nodes. Generally sensor node performs four basic important activities in the sensor network such as a sensing unit, a processing unit, a transceiver unit and power unit. Since a sensor node may sense many nodes at a time and transmitting, receiving data from those node may forms a queue. A sensor node has to communicate to all other neighbour nodes for data communication i.e. distribution of energy consumption of sensor node is also simultaneously done. This distribution of energy consumption forms a queue. Here in this paper we have discussed and proposed a mathematical queuing model to find an optimal solution to optimize energy consumption of the sensor node and to maximize system life time. Through an extensive simulation results show that the proposed model has good performances in the aspects of energy consumption and efficiency of the system network to prolong the system life time.
