Abstract :
In order to further improve the performance of wireless mesh networks (WMNs), a favorable solution is to enable mesh points (MPs) to run simultaneous transmissions on different wireless channels. In this paper, we propose a novel access scheme for multi-channel 802.11s WMN based on the concept of clustering and proxy. The new access scheme, which is called CHP, solves both the "hidden terminal" problem that exists in the traditional ad hoc networks and "hidden channel" problem that arises in a multi-channel network environment. Moreover, a QoS-guaranteed algorithm is designed in our access scheme, which improves the multiple channel utilization and reservation. Both theoretical analyses and simulation results show that the proposed scheme outperforms the existing protocols for WMNs in terms of the throughput and energy consumption.
