Utility based Power Control with FEC in Hexagonally deployed WSN
R. Valli, P. Dananjayan · 2012
The fundamental component of resource management in Wireless Sensor Network (WSN) is transmitter power control since they are miniature battery powered devices. An efficient power control technique is essential to maintain reliable communication links in WSN and to maintain the battery life of the sensor node and in turn the sensor network. Error control coding (ECC) schemes can improve the system performance and has an impact on energy consumption. This paper analyses a game theoretic model with pricing for power control in a sensor network considering ECC for random, square, triangular and hexagonal deployment schemes. The performance of the proposed power control scheme with RS and MIDRS code for WSN is evaluated in terms of utility, and energy consumption. Simulation results show that, for hexagonal deployment scheme, with the inclusion of ECC, the transmitting power of the nodes is reduced thereby saving energy and increasing the network lifetime.
