Location Service in Sensor and Mobile Actuator Networks
Li Jun Xu, Amiya R. Nayak, Ivan Stojmenović · 2010
In location service problem, mobile actuators send location update messages, whereas stationary sensors send search messages to learn latest position of actuators. The task is to minimize combined update and search message cost, while maximizing success rate of finding target actuator and subsequently routing to it. In the literature, many location service algorithms have been proposed for mobile ad hoc networks, and they can be directly applied to sensor and mobile actuator networks. This chapter reviews research efforts on this topic. It presents a classification of existing location service algorithms. The location update policies are discussed. The chapter also reviews some typical location services that cover a range of design choices. There are three classes of location service: flooding-based, quorum-based, and home-based, each with two subclasses at the second level.
