Abstract

Abstract:

Knowing the systematic throughput of a wireless network is an important thing before it can be efficiently used. Researches on the maximum throughput of a wireless network are mainly based on the fundamental network architecture in which nodes usually access the access point via one hop. The optimum throughput of the multi-hop Ad hoc network is related to network topology, node density, carrier sense range, hidden node effect and capture function and so on; so, the accurate estimation of it is a complicated job. An integrated analytical model which takes all the above factors into consideration is presented here. The modeling process involves the collision probability caused by both the hidden nodes and the nodes within the carrier sensing range; besides, it considers the capture function’s existence, which makes the analytical model more accurate. Through numerical analysis and network simulation, the newly deduced analytical model is proved to be able to match the practical results very well.

Key words: Ad hoc networks, carrier sense multiple access, hidden nodes, capture function, throughput
