Performance Analysis of Channel Access Model for MAC in Randomly Distributed Wireless Sensor Networks

Abstract

Medium Access control (MAC) is one of the fundamental problems in wireless sensor networks. The performance of wireless sensor network depends on it. The main objective of a medium access control method is to provide high throughput, minimize the delay, and conservers the energy consumption by avoiding the collisions. In this paper, a general model for MAC protocol to reduce the delay, maximize throughput and conserve the energy consumption in channel accessing in high density randomly distributed wireless sensor network is presented. 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 throughput of the channel access method with memory is better than without memory.

Energy Efficient clustering in Heterogeneous Wireless Sensor Networks using Degree of Connectivity

“…Energy is consumed in WSNs at three levels: sensing, transmission and network operation/processing. The major part of energy is consumed in transmission whereas sensing and operational cost of the network is minimal [3][4][5].…”
