The wireless mesh network is a new emerging technology exploiting the advantages of multiple radios and multiple channels. In this paper we have studied the channel assignment problem which is to assign channels to links in the network, and aimed at minimizing the network interference so as to improve the network throughput. The channel assignment problem is proved to be NP-hard. In this paper, we...
In this paper we have considered the channel assignment problem in multi-channel multi-radio wireless mesh networks. The problem is to assign channels to links in the network with the original topology preservation, and aim at minimizing the overall network interference which is proved to be NP-hard. We have first illustrated that the conversion from the channel assignment problem to the max k-cut...
In this paper, we address the problem of topology control in wireless sensor networks (WSNs). Taking energy consumption and reliability into account, we consider topology control to be a problem of multi-objective degree-constrained minimum spanning tree (mcd-MST) and present an improved discrete particle swarm optimization (PSO) algorithm for generating such topology schemes. The simulation results...
