Flooding protocols for wireless networks in general have been shown to be very inefficient and therefore are mainly used in network initialization or route discovery and maintenan...
—The hot spot problem is a typical byproduct of the many-to-one traffic pattern that characterizes most wireless sensor networks: the nodes with the best channel to the sink are ...
Until practical ad-hoc localization systems are developed, early deployments of wireless sensor networks will manually configure location information in network nodes in order to...
In order to process continuous queries over Wireless Sensor Networks (WSNs), sensors are typically organized in a Query Routing Tree (denoted as T) that provides each sensor with ...
In this paper we investigate a practical routing solution for a new class of wireless sensor networks where any node can be mobile anytime. Assuming GPS-enabled sensor nodes we pro...
