Power control with QoS constraints in WSN using game theoretic approach

Abstract

The major issue in wireless sensor network (WSN) is the power control since it is impossible to recharge or replace the batteries of the sensors. The sensors transmit at high power to make its transmission successful. Transmitting at high power not only reduces the lifetime of the nodes and that of the network, it also introduces excessive interference. Therefore, every node should transmit at minimal power while satisfying the quality of service (QoS) requirements. This paper proposes a power control game with error control coding (ECC) while considering the QoS requirements. The performance of the power control game satisfying QoS delay constraints with Reed Solomon (RS) and Multivariate Interpolation Decoded RS code (MIDRS) code for WSN is evaluated in terms of bit error rate (BER), throughput and delay.
