This paper presents a new route update strategy for performing proactive route discovery in Mobile Ad hoc Networks (MANETs). In this strategy, the rate at which route updates are sent into the network is controlled by how often a node changes its location by a required distance. We refer to this updating strategy as Minimum Displacement Update Routing (MDUR). We implemented MDUR on top of the Fisheye State Routing (FSR) protocol and investigated its performance by simulation. The simulations where performed in a number of different scenarios, with varied network mobility, density, traffic and boundary. Our results indicate that MDUR has lower levels of control overhead than FSR and achieves higher levels of throughput as the density and the level of traffic in the network is increased.
