Competent Wireless Multimedia Multicast in Multi-Rate Multi-Channel Mesh Networks
S. Kokila · International Journal for Research in Applied Science and Engineering Technology · 2019
Devices in wireless mesh networks can operate onmultiple channels and automatically adjust their transmissionrates for the occupied channels. This paper shows how to improveperformance-guaranteed multicasting transmission coverage for wireless multi-hop mesh networks by exploring the transmission opportunity offered by multiple rates (MR) and multiple channels (MC). Based on the characteristics of transmissions with different rates, we propose and analyze parallel low-rate transmissions (PLT) and alternative rate transmissions (ART) to explore the advantages of MRMC in improving the performance and coverage tradeoff under the constraint of limited channel resources. We then apply these new transmission schemes to improving the WMN multicast experience.The above interference becomes more intensive when multicasting multimedia data because of the high transmission rates and the long communication durations.I.
