Power Control Algorithm for Wireless Sensor Networks using N-Policy M/M/1 Queueing Model
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 7
Abstract
A critical issue in wireless sensor networks is the limited vailability of power and hence optimizing power is very important. In any sensor node, transitions from idle to busy state and vice versa consume most of the power. We propose a new scheme to reduce the power consumption of nodes by educing the number of transitions of the sensor node based on the number of packets in the queue i.e., queue threshold. We develop an analytical model of a wireless sensor network with finite buffer capacity and analyze the performance of the proposed scheme in terms of performance parameters such as power consumption and mean delay. We also derive the expression for the optimal value of threshold. Results show that the power consumption reduces by 42% for the optimal threshold value when compared to no threshold condition. We perform simulations and the results obtained show that the nalytical results match with the simulation results thus alidating the analytical model.
