Estimating the number of people in a crowded environment is a central task in civilian surveillance. Most vision-based counting techniques depend on detecting individuals in order...
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...
Scalability and extended lifetime are two critical design goals of any large scale wireless sensor network. A two-tiered network model has been proposed recently for this purpose....
In recent years, the data management community has begun to consider situations in which data access is closely tied to network routing and distributed acquisition: examples includ...
