Wireless sensor networks: a survey

Published: 15 March 2002 Publication History

Abstract

This paper describes the concept of sensor networks which has been made viable by the convergence of micro-electro-mechanical systems technology, wireless communications and digital electronics. First, the sensing tasks and the potential sensor networks applications are explored, and a review of factors influencing the design of sensor networks is provided. Then, the communication architecture for sensor networks is outlined, and the algorithms and protocols developed for each layer in the literature are explored. Open research issues for the realization of sensor networks are also discussed.

A comprehensive survey of sensor networks is presented in this paper, starting with their potential applications for military, environmental, health, and home or office use. The authors then discuss factors influencing sensor-network design, for example fault tolerance when sensor nodes fail due to lack of power or physical damage; the scalability and production costs of a million-node network; and operational constraints, including low power consumption, and autonomous adaptation to the environment. Power consumption is analyzed with respect to sensing, communication, and data processing. The communication architecture of sensor networks is the focus of the second part, starting with a discussion of several management planes, and three possible application-layer protocols. The authors then argue briefly that new types of transport protocols may also be needed, because of data-centric routing, as well as because of power-consumption and scalability issues. The network layer is described in more detail, and the authors argue that design power-efficiency considerations, data-centric operation, and attribute-based addressing and location awareness will be mostly influenced here. The authors provide convincing reasons why existing MAC protocols cannot be used, and outline both fixed-allocation and random-access versions of experimental MAC protocols for sensor networks. The paper is clear and easy to follow, and can be used as an introduction to the field of sensor networks. The authors provide a qualitative overview of the numerous experimental schemes and protocols for each layer of the protocol stack. The overview is illustrated with useful tables that help readers compare the schemes with each other. The authors also provide extensive references and URLs for a number of ongoing research projects in sensor networks. It needs to be noted, however, that the field is growing rapidly; a reader who wants to learn the field should supplement this survey with recent research papers from MobiCom and MobiHoc, and with a new WSNA workshop dedicated to sensor networks.
