Channel Allocation Strategies in Multi-Radio Multi-Channel Wireless Mesh Networks

Abstract

Wireless mesh networks have gained prominence as a versatile solution for providing ubiquitous connectivity in diverse environments. To overcome the challenges of limited bandwidth and interference in such networks, the concept of multi-radio multichannel configurations has emerged. In this paradigm, nodes are equipped with multiple radios, enabling concurrent communication over distinct frequency channels. The effective allocation of these channels among nodes is a critical concern to optimize network performance while mitigating interference. An extensive investigation of channel allocation techniques in multi-radio multichannel wireless mesh networks is presented in this paper. Both conventional and contemporary methods for effective channel allocation take into consideration shifting topologies, fluctuating traffic loads, and dynamic network conditions. Dynamic approaches that adjust to real-time interference patterns are discussed alongside static channel assignment techniques like graph coloring. The challenges of load balancing, interference management, and coordination overhead are examined in the context of channel allocation.
