Balanced media access methods for wireless networks

Abstract

The wireless medium is a s=ce shared resource in mobde computing. Consequently, the media access control (MAC) layer influences the fairness and robustness of the wireless network. According to the current MAC protocok, stations are not able to gain access equdy to the shared wireless medium. This problem is conunody known as the fairness problem. The fairness problem occurs mostly bemuse of the existence of hidden stations and the presumption of a non-Wy connected wird=s network topology. This paper addresses solutions to the fairness problem in wireless networks. persistent carrier sense mdtiple access based dgr ithms are proposed in which a fair wirel=s access for each user is accomplished using a precsdtiated N acce~Probabfity, Pij, . .
