Channel Diversity

In this article, the authors propose a new hybrid MAC protocol named H-MAC for wireless mesh networks. This protocol combines CSMA and TDMA schemes according to the contention level. In addition, it exploits channel diversity and provides a medium access control method that ensures the QoS requirements. Using ns-2 simulator, we have implemented and compared H-MAC with other MAC protocol used in Wireless Network. The results showed that H-MAC performs better compared to Z-MAC, IEEE 802.11 and LCM-MAC.

Voice Traffic

The IEEE 802.11e standard is mostly concerned with traffic differentiation in single-hop infrastructured wireless networks. Wireless mesh networks use several wireless hops in order to forward packets to their destination. A significant issue is that the standard does not map network characteristics into the access protocol parameters it provides. This paper investigates different configurations of the IEEE 802.11e access parameters in wireless mesh networks and proposes two configuration settings. Both proposals provide voice traffic service guarantee without significantly degrading the performance of other multimedia traffic classes, as demonstrated by simulation experiment results.

Research Problems

This article introduces a functional architecture supporting the wireless mesh networks for the IEEE 802.16 standard. Three essential techniques—collision avoiding, packet scheduling, and wireless routing—are intensively presented. Based on the mesh extension of the IEEE 802.16 medium access control (MAC) layer protocol and the relay-based characteristic of WMNs, the algorithms concerning those three essential techniques are briefly reviewed. The suitable algorithms for collision avoiding and packet scheduling mechanisms are analyzed. Meanwhile, the wireless routing algorithm for the proposal architecture is discussed. The future research work is presented and the research problems are focused.
