In recent years, Wireless Sensor Networks (WSNs) have emerged as a new powerful
technology used in many applications such as military operations, surveillance system …

A wireless sensor network (WSN) is composed of a large number of sensor nodes, relay
nodes, and a base station, that are deployed in an environment to collect information. WSNs …

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 …

The demand for maximum network lifetime in many mission-critical applications of wireless
sensor networks motivates the great significance to deploy as few sensors as possible to …

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

In a wireless sensor network (WSNs), probability of node failure rises with increase in
number of sensor nodes within the network. The, quality of service (QoS) of WSNs is highly …

In a mobile underwater acoustic wireless sensor networks (MUAWSN), one of the most
important challenging issues is coverage and connectivity during data transmission. It is very …

This paper presents a cross-layer communication protocol for Wireless Sensor Network
(WSN) enabled surveillance system for sensitive fenced areas, eg, nuclear/oil site. Initially …

Underwater wireless sensor networks (UWSNs) have been developed for underwater
applications, such as resource exploration, pollution monitoring, and tactical surveillance …

In a wireless sensor network where sensors are arranged into a flat topology, sensors near
the sink consume much more energy than sensors at the boundary of the network. Sensors …
