Title
Performance of ALOHA and CSMA in Spatially Distributed Wireless Networks
Abstract
In this paper the performance of unslotted ALOHA and CSMA are analyzed in spatially distributed wireless net- works. Users/packets arrive randomly in space and time accord- ing to a Poisson process, and are thereby transmitted to their intended destinations using a fully-distributed MAC protocol (either ALOHA or CSMA). An SINR-based model is considered, and a packet transmission is successful if the received SINR is above a threshold value for the duration of the packet. Accurate bounds to the probability of outage, which is a function of the density of transmissions, are developed for both MAC protocols. These bounds are used to evaluate the performances of ALOHA and CSMA, and to gain insight into the design of general MAC protocols for ad hoc networks. Moreover, CSMA with receiver- sensing is proposed to improve the performance of CSMA. I. INTRODUCTION
