Location Service for a Hybrid Network of Stationary Sensors and Mobile Actors

Project Description

Location service is crucial to heterogeneous sensor networks consisting of stationary sensor nodes and mobile devices. We explore design choices and parameter configurations for location services to achieve high energy-efficiency and packet-delivery ratio. Our main contributions are (1) an in-depth analysis of conditions for a generic location service to achieve a high packet-delivery ratio; (2) design optimization that achieves a significant reduction of the location-service overhead; (3) a technique of adapting the location service to the rate and distribution of data sources to achieve overall energy efficiency, and derivation of the break-even point of data rate for such adaptation.
