Latency avoidance by route assumption for reactive routing protocols

Mobile Ad-hoc Networks (MANETs) can be used to enable data transmissions if no communication infrastructure is available. One of the important tasks in such MANETs is the discovery of routes between the nodes. However, as MANET scenarios can be highly dynamic in terms of the number of participating nodes, the speed of the nodes, or the available energy, a lot of work has been spent into adaption of MANETs to such requirements. Therefore, special routing protocols have been developed. One type of such protocols are reactive routing protocols, where routes are only searched on-demand with the drawback of a latency during the route finding process. In this paper, we present our new approach Latency Avoidance by Route Assumption (LARA) based on the Ad-hoc On-Demand Multipath Distance Vector routing protocol to avoid such latency by monitoring routing packets and assuming probable routes based on the gained knowledge.
