Impact of Heterogeneity on Coverage and Broadcast Reachability in Wireless Sensor Networks
Computer Communications and Networks
While most existing research efforts in the area of wireless sensor networks have focused on networks with identical nodes, deploying sensors with different capabilities has become a feasible choice. In this paper, we focus on sensor networks with two types of nodes that differ in their capabilities, and discuss the effects of heterogeneity of sensing and transmission ranges on the network coverage and broadcast reachability. Our work characterizes how the introduction of a few sensor nodesdoi:10.1109/icccn.2006.286246 dblp:conf/icccn/WangWAM06 fatcat:d7rrbpisd5dwzcdgphvryyerxm
