Neighbor Discovery With Activity Monitoring in Multichannel Wireless Mesh Networks
Source: Imperial College London
One way of improving performance of wireless mesh networks is to use multiple non-overlapping channels. At the same time, the mesh network must continuously self-adapt to varying radio conditions and topology changes. Thus, the authors propose a neighbor discovery protocol that fits the requirements of multichannel networks while dealing at the same time with the deafness problem. The proposed scheme also takes advantage of neighbor discovery to continually monitor channel activity. They provide a theoretical analysis of the average discovery time. Their simulations show that the solution integrated within Molecular MAC, a multichannel MAC, results in efficient discovery and channel assignment.
