Channel Allocation and Routing in Hybrid Multichannel
Multiradio Wireless Mesh Networks
Many efforts have been devoted to maximizing network throughput in a multichannel multiradio
wireless mesh network. 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. In addition, we also 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.
