The coverage optimization problem has been examined thoroughly for omni-directional
sensor networks in the past decades. However, the coverage problem in directional sensor …

Node deployment is one of the most crucial issues in wireless sensor networks because it
determines the deployment cost, the detection capability of the networks, and even the …

Differing from general omnidirectional wireless sensor networks, in the directional sensor
networks, the effective sensing range of sensors is characterized by directionality and …

Visual sensor networks (VSNs) are becoming increasingly popular in a number of
application domains. A distinguishing characteristic of VSNs is to self-configure to minimize …

Camera sensor networks (CSNs) are gradually being used in a tele-intensive care unit (tele-
ICU), providing useful patient information to remote intensivists. Intensivists wish to focus on …

This paper introduces a new wireless sensor network planning problem referred to as the
Optimal Sensor Configuration (OSC) problem. In this problem, the goal is to find an optimal …

Unlike conventional scalar sensors, camera sensors at different positions can capture a
variety of views of an object. Based on this intrinsic property, a novel model called full-view …

Good deployment of sensors empowers the network with effective monitoring ability.
Different from omnidirectional sensors, the coverage region of a directional sensor is …

We present a multi-stage optimization method for efficient sensor deployment in traffic
surveillance scenarios. Based on a genetic optimization scheme, our algorithm places an …

A directional sensor network is different from conventional wireless sensor networks. It uses
directional sensors instead of omnidirectional ones in the network for different applications …
