Optimizing delay for MAC in randomly distributed wireless sensor networks

Abstract

Medium access control is a fundamental problem in wireless sensor network. It determines the performance of sensor network. The prime design goal of a medium access control method is to provide high throughput, reduce the delay, and minimize collision and energy consumption. In this paper, we present a general model for MAC protocol to reduce the delay in channel accessing in high density randomly distributed wireless sensor network. The proposed model is simulated using MATLAB. The simulation results show that the average delay for sensors with sufficient memory is lower than sensors without memory. Further, the proposed model is tested using S-MAC protocol, and the better result is obtained.
