Node reliance : an approach to extending the lifetime of wireless sensor networks

open access: yes, 2010
A Wireless Sensor Network (WSN) consists of a number of nodes, each typically having a small amount of non-replenishable energy. Some of the nodes have sensors, which may be used to gather environmental data.

Extending the Lifetime of Sensor Networks through Adaptive Reclustering

open access: yesEURASIP Journal on Wireless Communications and Networking, 2007
We analyze the lifetime of clustered sensor networks with decentralized binary detection under a physical layer quality-of-service (QoS) constraint, given by the maximum tolerable probability of decision error at the access point (AP).
