Location-Aware In-Network Monitoring in Wireless Sensor Networks

Overview Wireless Sensor Networks offer new prospects for pervasive monitoring of natural and industrial environments. The stringent resource constraints of sensor nodes rule out many solutions known from classical distributed systems. This paper presents a data-centric and location-aware procedure to perform in-network evaluation of queries in sensor networks. The algorithm is a hybrid of geographic hash tables and in-network aggregation. It increases data availability and accounts for topology changes and generates mostly local network traffic.
