Video is principal information that facilitates commander's immediate command decision.Due to fading characteristics of radio link, however, it is difficult to stably transmit video in a multi-hop wireless environment.In this paper, we propose a MANET structure composed of a link adaptive routing protocol and a TDMA MAC protocol to stably transmit video traffic in a ultra-narrowband video streaming network.The routing protocol can adapt to link state change and select a stable route.The TDMA protocol enables collision-free video transmission to a destination using multi-hop dynamic resource allocation.As a result of simulation, the proposed MANET structure shows better video transmission performance than proposed MANET structure without link quality adaption, AODV with CSMA/CA, and OLSR with CSMA/CA structures.
