Medium Access Guarantee in Wireless Mesh Network

Abstract

The wireless mesh network WMN based on the 802.11s standard is a new concept that allow to broaden the network coverage in order to maximize the number of client stations, taking advantage of the internet connection.This technology presents several problems about certain levels of the congestion, especially the non-exploitation of the resource parts caused by the unnecessary rebroadcast and the collision between packets in the queues. As a result, we obtain the unfairness of medium access.The problem of the rebroadcast of unnecessary packets is controlled by the rebroadcast control mechanisms. One of these mechanisms had been chosen, that in a recent work they studied the capacity of the network that adopt this mechanism .The conclusions of this work, will allow us to define an algorithm to organize the access of flows to the medium, and give more opportunity to the far nodes to occupy a part of the medium.
