Abstract

In a multi-hop wireless network, each node is able tosend a message to all of its neighbors that are locatedwithin its transmission radius. In a flooding task, a sourcesends the same message to all the network. Routingproblem deals with finding a route between a source anda destination. In the activity-scheduling problem, eachnode decides between active or passive state. We presenta scheme whose goal is to prolong network life whilepreserving connectivity. Each node is either active or hasan active neighbor node. Routing and broadcasting arerestricted to active nodes that create such dominating set.Activity status is periodically updated during a shorttransition period. The main contribution of this article isto propose new metrics for previously studied source - independent localized dominating sets, based on combinations of node degrees and remaining energylevels, for deciding activity status.
