An adaptive holdoff algorithm based on node state for IEEE 802.16 mesh mode with coordinated distributed scheduling
Wireless mesh networks (WMNs) are one of the key features of beyond 3G system because of their flexible and lowcost deployment. IEEE 802.16 mesh mode has recently emerged as an alternative protocol for establishing WMN. Because the WMN is used as wireless backbone network, the design of WMN protocol should target a high network throughput. Then, in IEEE 802.16 mesh standard, the performance improvement is limited by the holdotT algorithm in the bandwidth reservation procedure. In this paper, we propose an adaptive holdotTalgorithm for IEEE 802.16 mesh mode with coordinated distributed scheduling. The proposed holdotT algorithm improves network throughput by adaptively adjusting the transmission holdotT exponent according to current node state. In addition, the proposed holdotT algorithm maintains the backward compatibility with the IEEE 802.16 mesh standard and does not require any information from other layers. Simulation results show that the proposed holdotT algorithm performs bette...
