Interference-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 Broadcast Channel Assignment Mechanism based on The Broadcast Tree for Multi-radio Multi-channel Wireless Mesh Networks
In recent years, Cognitive Radio (CR) technology has largely attracted significant studies and research. Cognitive Radio Ad Hoc Network (CRAHN) is an emerging selforganized, multi-hop, wireless network which allows unlicensed users to opportunistically access available licensed spectrum bands for data communication under an intelligent and cautious manner. However, in CRAHNs, a lot of failures ...
متن کاملMulti-channel MAC Protocol in Cognitive Radio Networks
Cognitive radio represents an efficient way to utilize the available spectrum in Wireless networks by offering the unlicensed users (Secondary users) the opportunity to use an available spectrum for the licensed users (Primary users) when they are not active. In this paper, some cognitive MAC protocols are discussed with a brief introduction to Multi Channel MAC protocols.
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 کاملImplementation of Channel Hopping Algorithm in Cognitive Radio Network & MANET
Dynamic spectrum access by the unlicensed secondary users (nodes) in the Cognitive Radio Network without harmful (potential) interference to the licensed users is an intelligent and efficient use of the Licensed Spectrum Bands. The nodes in a cognitive radio network(CRN) performs periodic local spectrum sensing & dynamically detects the vacant or unused spectrum around them in the form of free ...
