Efficient channel assignment method for multimedia traffic in wireless mesh networks

Abstract

SUMMARYIn wireless mesh networks, the availability of spectrum should be utilized efficiently because the exchanging of traffic rate of multimedia applications is increasing day to day. The traffic of multimedia content may degrade the network performance in terms of high packet loss and throughput degradation because of asynchronous behavior between the sender and the receiver. The proposed Efficient Channel Reservation and Assignment (EchRA) results in successful originating and handing off of multimedia call transmissions using the four dimensional Markov chain process. The EChRA algorithm, proposed in this paper, achieves the maximum throughput performance considering the parameters of blocking probability, dropping probability, and synchronized dwell time between the source and destination. The quality of service is guaranteed by sharing the available slots and by using efficient queuing model to service the incoming and handoff calls, and henceforth, the successful completion of handoff calls rate is increased.

Review of channel assignment approaches in multi-radio multi-channel wireless mesh network

“…In [39,40], the packet drop and blocking probability has been used to compute the performance of the channel and a channel with minimum probability is selected as recommended channel. The metric is used to reduce the delay in the channel and ensure the ongoing transmission is completed without interruption delay.…”

Cluster‐based mobility management algorithms for wireless mesh networks

“…In Misra et al, the authors present a work on medium access control mechanism for heterogeneous networks. In Pounambal and Venkata Krishna, the authors present a work on channel assignment techniques for multimedia traffic in WMNs. But WMNs are different from other networks.…”
