Abstract
Recent advances in wireless works have led to many new protocols specifically
designed for works where energy awareness is an essential consideration. Most of the
attention, however, has been given to the routing protocols since they might differ depending on
the application work architecture. This paper surveys recent routing protocols for
works and presents a classification for the various approaches pursued. The three
main categories explored in this paper are data-centric, hierarchical and location-based. Each
routing protocol is described and discussed under the appropriate category. Moreover,
protocols using contemporary methodologies such work flow and QoS modeling are also
discussed. The paper concludes with open research issues.
1. Introduction
Recent advances in micro-electro-mechanical systems (MEMS) and low power and highly
integrated digital electronics have led to the development of micro sensors [1][2][3][4][5]. Such
sensors are generally equipped with data processing munication capabilities. The
sensing circuitry measures ambient conditions related to the environment surrounding the sensor
and transforms them into an electric signal. Processing such a signal reveals some properties
about objects located and/or events happening in the vicinity of the sensor. The sensor sends
such collected data, usually via radio transmitter, to mand center (sink) either directly or
through a data concentration center (a gateway). The decrease in the size and cost of sensors,
resulting from such technological advances, has fueled interest in the possible use of large set of
disposable unattended sensors. Such interest has motivated intensive research in the past few
years addres
