Routing in the frequency domain
Abstract The design of single transceiver based multichannel multi-hop wireless mesh networks focuses on the trade-off between rapid neighbor synchronization and maximizing the usage of all available channels. Existing designs are confined to the MAC layer and scale poorly as the network grows in coverage and density. We recently proposed Dominion as a cross-layer architecture that includes both medium access control and routing. Dominion eliminates the need for neighbor synchronization at the MAC layer and pushes the intelligence up the network stack. At the MAC layer, a node switches channels according to a deterministic schedule which guarantees that a node converges with each of its neighbors periodically. At the network layer, the channel-hopping aware routing substrate routes traffic along the frequency domain, i.e., packets along a multi-hop route generally traverse via multiple channels. In this paper, we present the complete design, analysis and evaluation of Dominion and ma...
