| dc.description.abstract | Wireless mesh networks (WMN) are the communication networks made up of radio nodes organized in a mesh topology. In recent years there are many applications like video survelliance, video conferencing that have been implemented over these kind of networks. As wireless mesh networks become more popular and their size and complexity continues to grow, mesh networks that contain multiple hops become increasingly vulnerable to problems such as bandwidth degredation, radio interference and network latency. In extreme cases, where voice and video applications are heavily at work, a complete connection loss can occur when latency and RF interference reach unacceptable levels. This thesis work studies video multicasting in large scale areas using wireless mesh networks. The focus is on the use of internet access gateways that allow a choice of alternative routes to avoid potentially lengthy multi-hop wireless paths with low capacity. We mainly get inspired from the set of heuristic-based algorithms that were described at the paper named \Resource aware video multicasting via Access Gateways in Wireless Mesh Networks": the two-tier integrated architecture algorithm (TIA), the weighted gateway uploading algorithm (WGU) and the linkcontrolled routing tree algorithm (LCRT). Two enhancements were developed for both TIA and LCRT, and afterwards performance analysis have been made to obtain the contribution of the new scheme. | |
