A New Method based on Intelligent Water Drops for Multicast Routing in Wireless Mesh Networks
In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...
متن کاملInterference-Aware and Cluster Based Multicast Routing in Multi-Radio Multi-Channel Wireless Mesh Networks
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...
متن کاملA Utility-based Framework for Joint Channel, Topology, and Routing Control in Wireless Mesh Networks⋆
We define a utility-based framework for joint channel assignment, topology control and routing in multi-rate multi-radio wireless mesh networks, and present a greedy algorithm for solving the corresponding optimization problem. A key and novel feature of the proposed approach is the support for different target objectives, which are defined as utility functions of the MAC layer throughput, that...
متن کاملA Novel Multicast Tree Construction Algorithm for Multi-Radio Multi-Channel Wireless Mesh Networks
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...
متن کاملImproving throughput and fairness by improved channel assignment using topology control based on power control for multi-radio multi-channel wireless mesh networks
Multi-radio multi-channel (MRMC) wireless mesh networks (WMNs) achieve higher throughput using multiple simultaneous transmissions and receptions. However, due to limited number of non-overlapping channels, such networks suffer from co-channel interference, which degrades their performance. To mitigate co-channel interference, effective channel assignment algorithms (CAAs) are desired. In this ...
