This paper proposes a distributed channel assignment algorithm CLBCA (Channel Load Based Channel Assignment) and a hybrid routing protocol TOIRP for multi-channel wireless mesh networks. A new routing metric CETTI is proposed for its advantage of quantifying the interference of communication by distinguishing interference into inter-flow interference and(More)
In this paper, we propose a parallel ant colony optimization based metaheuristic for solving the maximum-weight clique problem, which is a variation of the maximum clique problem. The advised parallel computing model is based on concept of cooperation among multiple ant colonies system. The cooperation system consists of a message center and a number of ant(More)
