Compressive Data Gathering

13.1 Introduction

This chapter considers the data gathering problem in a large-scale wireless sensor

network. Such a large-scale data gathering sensor network finds a variety of applica-

tions in habitat monitoring, traffic control, and surveillance. In general, large-scale

sensor data gathering is accomplished through multi-hop routing from individual

sensor nodes to the data sink. Successful deployment of such large-scale sensor net-

works faces two major challenges in effective global communication cost reduction

and in energy consumption load balancing.

The need for global communication cost reduction is obvious because such sensor

networks typically are composed of hundreds to thousands of sensors, generating ...
