An ad-hoc network is a typically a dynamic collection of nodes capable of communicating therebetween without the aid of pre-established infrastructure. Ad-hoc networks differ from traditional networks in that the topology of interconnections between nodes is inherently dynamic and not fixed. Generally, the routing protocols belong to two groups: proactive and reactive. Proactive protocols attempt to maintain correct and up-to-date routing information at every node. Reactive protocols, in turn, collect necessary routing information only if a pair of nodes are to establish a communication. In accordance with embodiments of the invention a reactive ad-hoc network protocol is disclosed that uses controlled flooding to broadcast packets of information within the ad-hoc network. Furthermore, the ad-hoc network protocol does not maintain up-to-date routing information at every node in an ad-hoc network and does not utilize specific control messages to assure that packets within the ad-hoc network follow optimal paths.
