- Abstract
The development and widespread use of real-time constrained multi-media application in MANET has resulted in the need to optimize or update current routing mechanisms. This paper proposed a QoS routing mechanism for multi-media transmission under real-time constraint in MANET, named ad-hoc on-demand distance vector routing based on location information and link-stability evaluation (LL-AODV). The mechanism abstracts the routing problems into the shortest path problem of an undirected weighted graph in which the weights of the paths are determined by the duration time of links, the residual battery and energy consumption of nodes, and utilizes the shortest path algorithm to determine a feasible transport path. We use a prediction model of the duration time of links to predict the probable time the link may maintain, and that improves the deficiency of the AODV routing mechanism, which only uses hop counts as the transport path metric. Furthermore, it adopts periodical maintenance and rescue maintenance to ensure an alternative path can be found in time to transmit data, and thus improves the reliability of multi-media data transmission under real-time constraint. Simulation and the experimental results showed that the mechanism could provide a better QoS route for the multi-media transmission under real-time constraint in MANET.
