A Distributed Method for Compressive Data Gathering in Wireless Sensor Networks

摘要

Compressive data gathering (CDG) has recently emerged to provide energy efficient data aggregation in wireless sensor networks. CDG requires efficient routing (forwarding) trees to gather encoded data from sensor nodes to the sink. This paper presents a decentralized method for the compressive data gathering problem (DCDG). Our method allows each sensor node to locally make a decision in constructing and maintaining the forwarding trees and has minimal complexity and overhead with outstanding performance.
