Support Qos Routing, Accurate State Information in MANET
To support QoS routing, accurate state information (such as energy level and queue length) should be available and manageable. But due to bandwidth constraints, communication costs, high loss rate and the dynamic topology of MANETs, getting and keeping up-to-date state information is a very complex task, if at all feasible. In this paper, the authors use Optimized Link State Routing (OLSR) as the underlying routing protocol. This research reports the quantification of state information accuracy under different traffic rates. State information accuracy is defined as how far off is the believed QoS-related state information from its actual value.
