multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

Channel assignment has been extensively studied in wireless network such as cellular network, with the appearance of the new multi-radio multi-channel network such as wireless mesh network and cognitive radio network, channel assignment in such network has been a hot research topic again. In this paper, we use game theory to study the channel assignment problem, we model channel assignment in m...

Channel assignment is one of the most important issues in the multi-radio multi-channel wireless mesh networks. An improper channel assignment may lead to network partition or link failure. In this paper we focus on the channel assignment problem with the original topology preservation for the multi-radio mesh networks, and aim at minimizing the overall network interference. We have formulated ...

To improve the capacity of wireless ad hoc networks by exploiting multiple available channels, we propose a distributed channel assignment protocol that is based on a cross-layer approach. By combining channel assignment with routing protocols, the proposed channel assignment protocol is shown to require fewer channels and exhibit lower communication, computation, and storage complexity than ex...

In this paper, we consider the call admission problem in cellular network with two classes of voice users. In the first part of paper, we introduce a two-threshold guard channel policy and study its limiting behavior under the stationary traffic. Then we give an algorithm for finding the optimal number of guard channels. In the second part of this paper, we give an algorithm, which minimizes th...
