Maintaining fairness in Wireless Mesh Networks (WMNs) is quite important but has been given less attention relative to other aspects such as capacity maximization and maintaining connectivity. IEEE 802.11 MAC protocol has been used as the standard for WMNs although it has been initially designed to operate in wireless local area networks. It is known to be unfair in multi-hop networks. This unfairness...
In this paper, we propose a dynamic approach for transmission holdoff time in IEEE 802.16 mesh mode with Coordinated Distributed Scheduling scheme (C-DSCH). This scheme allows different nodes to use different holdoff time values according to current node need of the control-plane bandwidth. Nodes that need to establish data scheduling use small XmtHoldoffExp, while others use large XmtHoldoffExp....
Being an evolution of IEEE 802.16e, IEEE 802.16j mobile multi-hop relay (MMR) is proposed to gain coverage extension and throughput enhancement. Although the IEEE standard 802.16j-2006 has not been published yet, the second version of 802.16j Draft Standard (802.16j D2) has been released in 2007. In this paper, for the first time, we evaluate the MAC performance of the Draft Standard based on the...
