A mobile wireless sensor network (M-WSN) consists of sensors equipped with locomotive
platforms to allow movement after initial deployment. M-WSNs are useful for environments …

Rarely occurring events present unique challenges to energy constrained systems designed
for long term sensing of their occurrence or effect. Unlike periodic sampling or query based …

It is well-known that placing disks in the triangular lattice pattern is optimal for achieving full
coverage on a plane. With the emergence of wireless sensor networks, however, it is now no …

Early detection of forest fires is the primary way of minimizing their damages. We present the
design of a wireless sensor network for early detection of forest fires. We first present the key …

Target tracking systems, consisting of thousands of low-cost sensor nodes, have been used
in many application domains such as battlefield surveillance, wildlife monitoring and border …

In this paper, we study deployment patterns to achieve full coverage and k-connectivity (k≤
6) under different ratios of the sensor communication range (denoted by R c) to the sensing …

In a wireless sensor network (WSN), connectivity enables the sensors to communicate with
each other, while sensing coverage reflects the quality of surveillance. Although the majority …

A magnanimous number of collaborative sensor nodes make up a Wireless Sensor Network
(WSN). These sensor nodes are outfitted with low-cost and low-power sensors. The routing …

In this paper, we propose deployment patterns to achieve full coverage and three-
connectivity, and full coverage and five-connectivity under different ratios of sensor …

Deriving the critical density (which is equivalent to deriving the critical radius or power) to
achieve coverage and/or connectivity for random deployments is a fundamental problem in …
