Performance Evaluation of a Medium Access Control Protocol for IEEE 802.11s Mesh Networks

This paper presents a performance evaluation study for the Common Control Channel (CCC) protocol, a medium access control protocol suitable for wireless mesh networks. This protocol was submitted in July 2005 to the IEEE 802.11 Task Group s, which is responsible for developing a mesh-networking standard. CCC extends the distributed IEEE 802.11e MAC protocol to multi-channel operation for single- and multiple-radio devices, and enables additional valuable features. As demonstrated by the simulation results, CCC achieves impressive delay and aggregate throughput performance, and thus offers distributed channel access for backbone meshes with delay properties suitable for VoIP and other QoS-sensitive applications.
