A novel analytical model to validate the ieee 802.11 mac performance in wireless multi-hop grid networks

Abstract

The IEEE 802.11 MAC is originated design to local wireless network that suites for single hop fashion. Nowadays, it becomes de facto standard for many emerged multi-hop network technologies such as sensor network, vehicle ad-hoc network or mesh network. However, the standard employed CSMA/CA mechanism has to face with potential challenges which come from characteristics of multi-hop transmission environment. In which, node distribution is one of key factors concerned to the successful transmission probability of a connection and overall network performance. Hence, this paper proposes a novel analytical model of IEEE 802.11 MAC based wireless multi-hop network to validate main network performance parameters in grid fashion.
