Data Transmission and Base-Station Placement for Optimizing the Lifetime of Wireless Sensor Networks

Free registration required

Executive Summary

In this paper, the authors study the fundamental optimization problem in Wireless Sensor Networks of base-station positioning such that data from the sensors may be transmitted to it in an energy-efficient manner. They primarily consider the setting where a sensor transmits all of its data directly to the base-station or relays it via one other node. This setting provides two benefits: low duty-cycling due to limited synchronization requirements between nodes and low end-to-end delay due to the limited number of hops in the routes. Given the battery limitations of the sensor nodes, their objective is to maximize the network lifetime.
