Abstract

We propose a generic framework for distributed broadcastingin ad hoc wireless networks. The approach is basedon selecting a small subset of hosts (also called nodes) toform a forward node set to carry out a broadcast process.The status of each node, forwarding or non-forwarding, isdetermined either by itself (self-pruning) or by other nodes(neighbor-designating). Node status can be determinedat different snapshots of network state along time (calledviews) without causing problems in broadcast coverage. Asufficient condition, called coverage condition, is given fora node to take the non-forward status. Such a condition canbe easily checked locally around the node. Several existingbroadcast algorithms can be viewed as special cases of thegeneric framework with k-hop neighborhood information.A comprehensive comparison among existing algorithms isconducted. Simulation results show that new algorithms,which are more efficient than existing ones, can be derivedfrom the generic framework. This work is an extension toan early work in which only self-pruning methods are discussed[16].
