Challenges and Experiences of Building Multimedia Transmission Testbeds in Wireless Mesh Network

Wireless mesh networks (WMN), with static wireless back-bone and multi-hop communication, as protocols typically employed in WMN are, for the most part, not designed for real-time communications. WMNs experimentation is subjected to stochastic factors such as channel contention, interference, node mobility and access latency add delay and degrade the quality of the stream, pose new design challenges. In this paper, we report on our effort and experience to design our WMN testbed. As a case study, second, we introduce the TJU MeshNet architecture. We share our lessons learned from this effort and believe that they will be valuable to other researchers who develop experimental wireless mesh networks and business applications.
