Channel allocation and routing in hybrid multichannel multiradio wireless mesh networks
0 likes77 views
The document proposes a hybrid channel allocation and routing approach for multichannel multiradio wireless mesh networks. It presents an Adaptive Dynamic Channel Allocation (ADCA) protocol that considers both throughput and delay for channel assignment. It also proposes an Interference and Congestion Aware Routing (ICAR) protocol for hybrid networks with static and dynamic links that balances channel usage. Simulation results show ADCA reduces packet delay without degrading throughput, and the hybrid approach adapts better to changing traffic than static-only networks with lower overhead and delay than existing hybrid methods.

Most current solutions are based on either purely static or purely dynamic channel allocation approaches. In this paper, we propose a hybrid multichannel multiradio wireless mesh networking architecture, where each mesh node has both static and dynamic interfaces. We first present an Adaptive Dynamic Channel Allocation protocol (ADCA), which considers optimization for both throughput and delay in the channel assignment. We propose an Interference and Congestion Aware Routing protocol (ICAR) in the hybrid network with both static and dynamic links, which balances the channel usage in the network. Our simulation results show that compared to previous works, ADCA reduces the packet delay considerably without degrading the network throughput. The hybrid architecture shows much better adaptivity to changing traffic than purely static architecture without dramatic increase in overhead, and achieves lower delay than existing approaches for hybrid networks.
