TLDR
A new, realistic model of node motion based on the movement of vehicles on real street maps is presented, which is compared with the Random Waypoint mobility model, the most widely used mobility model.Abstract:
Without realistic modeling of node mobility, simulation evaluation of performance of mobile ad hoc networks may not correlate well with performance in a real deployment. In this work, we present a new, realistic model of node motion based on the movement of vehicles on real street maps. Our model can be used with the ns-2 network simulator. We compare our model with the Random Waypoint mobility model, the most widely used mobility model. Results show that, in many ways, the Random Waypoint mobility model is a good approximation for simulating the motion of vehicles on a road, but there are situations in which our new model is better suited.read more

Dynamic Source Routing in Ad Hoc Wireless Networks.
David B. Johnson,David A. Maltz +1 more
TL;DR: In this article, the authors present a protocol for routing in ad hoc networks that uses dynamic source routing, which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently.
