Abstract

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.
