In this paper, we present Hierarchy-Based Anycast Routing (HAR), a routing protocol for collecting data over multi-hop, wireless sensor networks. The design of the protocol aims t...
An important problem in mobile ad-hoc wireless sensor networks is the localization of individual nodes, i.e., each node’s awareness of its position relative to the network. In t...
Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an...

Abstract— Wireless access networks scale by replicating base stations geographically and then allowing mobile clients to seamlessly “hand off” from one station to the next as...
Mobile elements, which can traverse the deployment area and convey the observed data from static sensor nodes to a base station, have been introduced for energy efficient data co...
