“…Distributed channel selection algorithms avoid the single point of failure by optimizing the channel assignment in the local neighborhood of mobile station. In [5] the authors proposed an on demand channel assignment protocol, that assigns links to channels when these links become active. When a new flow is forwarded over a not used link, it assigns the activated link to a wireless interface, corresponding to a wireless channel.…”

In this paper we present a cross layer topology preserving channel selection protocol for a two interface wireless mesh network. The presented protocol is a cluster driven channel selection protocol, preserving a single interface to maintain connectivity and using the other interface to participate in small clusters. The clusters are organized by an independent set clustering algorithm, in which the cluster head dictates the operating channel for the local cluster. We show that the channel selection algorithm doubles the capacity for both a regular grid and a random topology.

“…(ii) Channel Assignment without Congestion Control. Bouckaert et al [10] have proposed an adaptive block addressing (ABA) scheme for logic address assignment as well as for network auto-configuration purpose. Their scheme takes into account the actual network topology and thus is fully topology-adaptive.…”

SUMMARYIn Multichannel Wireless Mesh Network architecture, topology discovery, traffic profiling, channel assignment and routing are essential. From the existing work done so far, we can observe that no work has been carried out on the combined solution of multichannel assignment with routing protocol and congestion control. In this paper, we propose to design a Distributed Multichannel Assignment with Congestion control (DMAC) routing protocol. In this protocol, a traffic-aware metric provides the solution for multichannel assignment and congestion control. Hence, the proposed protocol can improve the throughput and channel utilization to a very high extent. The proposed algorithm avoids self-interference by not assigning a channel to any link whose incident links have already been assigned channels. By our simulation results, we show that our proposed protocol attains high throughput and delivery ratio along with reduced delay.
