Application of chain-type multi-hop networks for unmanned aerial vehicle in the mine

Ad hoc network is a multi hop, non center, self-organizing wireless network, also known as multi hop network, no infrastructure network or self-organizing network. The entire network has no fixed infrastructure, and each node is mobile, and can be maintained in any way dynamically with other nodes. In this paper, Ad Hoc network is used for multi robot communication for mine disaster searching. the paper summarizes the lack of fairness in MIMC-AODV protocol, the problem of wasting time in SA-TDMA protocol, the technology of joint channel assignment and time slot allocation, and introduces the multi channel time slot allocation cross - layer protocol (MSAT) combined with AODV and TDMA.MSAT protocol in video transmission performance is more suitable for the application of the online video transmission based on multi hop Ad Hoc network of UAV in the mine.
