Abstract

Broadcast is a fundamental operation for wireless mesh networks. It plays an important role in the communication protocol design. Many existing work have studied the NP-hard broadcast problem in multi-hop networks. However, most of them assume a single-channel and single-radio wireless network model. We investigate broadcast in multi-channel multi-radio wireless mesh networks. In multi-channel multi-radio wireless mesh networks, the wireless interference due to simultaneous transmissions from the same channel and intra-node interference render the broadcast problem nontrivial. In this work, we analyze the performance of a broadcast protocol with MAC-layer scheduling under different networking conditions. We also explore the performance improvement by incoporating the neighbor elimination scheme with the broadcast protocol. We analyze the performance improvement of the integrated protocol in environments of multi-channel multi-radio and multi-rate.
