abstract
We consider broadcasting protocols in mobile ad hoc networks that propagate a message from a node to all of the nodes of a network. In order to reduce the impact of mobility on protocols, instead of relying on the frequently changing communication topology, our approaches depend on a less frequently changing and more stable characteristic - the distribution of mobile nodes. We propose two broadcasting approaches. For each approach, we provide specific constraints on distribution and mobility of mobile nodes to guarantee that all the nodes receive the broadcast data. Under these constraints, given a network with area A, our approaches achieve broadcasting in O (A/R2) steps, where R is the transmission range. Copyright 2005 ACM.
