Wireless Mesh Networks (WMNs) are consist of mesh routers. Mesh routers are built with multiple radios for improving capacity of network with the assignment of different frequency bands (channels). Establishment of routing is very important for getting good output or achieving good performance in multi radio wireless networks. In this paper we have proposed Weighted Cumulative Consecutive Confl...

Existing literature on multicast routing protocols in wireless mesh networks (WMNs) from the view point of the links involved in routing are divided into two categories: schemes aiming at the NP-hard problem of minimal interference multicast tree construction. In contrast, other methods develop network coding-based solutions with the main objective of throughput maximization which can effective...

Time-Spread Multiple-Access (TSMA) protocols are scheduled access protocols for mobile multi-hop radio networks that guarantee deterministic access to the shared channel regardless of the possibility of radio interference. In scheduled access methods, time is considered to be slotted and time slots are cyclically organized into frames. In general, the shorter the frame, the more efficient the p...

The fundamental limit that is imposed on any wireless system is due to the radio channel. Propagation and channel models are essential for the analysis and simulation of wireless systems. Knowledge of the radio channel is essential to the development and deployment of a wireless system. Radio channel models are used to support research into methods for mitigating channel impairments, such as th...

Decreasing hardware prices enables increased performance in wireless networks to a low cost. By adding an extra WLAN radio card to existing single radio network platforms, the possibility to utilize additional frequencies arise and opens the world of multi-channel, multi-radio (MCMR). In this report, we investigate di erent approaches to make as good use of MCMR as possible. A hybrid technique ...

In this paper, we address the channel assignment problem in a multi-radio mesh network that involves assigning channels to radio interfaces for eliminating the effect of wireless interference. Due to the insufficient number of frequency channels and available radios per node, interference is still present which limits the available bandwidth on wireless links and eventually decreases the achiev...

Multichannel multi radio wireless mesh networking is an emerging technology that can support numerous multimedia applications. Efficient channel assignment is essential in Multichannel multi radio wireless mesh network deployments to support QoS requirements, i.e., delay bandwidth, throughput and packet loss ratio to enable such QoS-demanding multimedia applications. This paper proposes QoS awa...

Within the wireless mesh network, a bottleneck problem arises as the number of concurrent traffic flows (NCTF) increases over a single common control channel, as it is for most conventional networks. To alleviate this problem, this paper proposes a two-stage coordination multi-radio multi-channel MAC (TSC-M2MAC) protocol that designates all available channels as both control channels and data c...
