MORA: a movement-based routing algorithm for ad hoc networks

In an ad hoc environment with no wired communication infrastructure, mobile hosts necessarily operate as routers, in order to provide network connectivity. Since mobile ad hoc networks change their topology frequently and without prior notice, routing in such networks becomes a challenging task. In this paper we present MORA, a movement-based routing algorithm for mobile ad hoc networks. The algorithm is completely distributed, since nodes need to communicate only with direct neighbors in their transmission range, and utilizes a specific metric, which exploits not only the position, but also the direction of movement of mobile hosts.
