In this work a new method is proposed to obtain the deployment of sensor nodes with a maximum coverage area using a minimum number of sensor nodes in three-dimensional surfaces. The deployment is performed using the dual Delaunay triangulation/Voronoi Diagram. The position selection process considered the vertices as candidate positions and the sensing radius. The positions were selected based on...
Wireless sensor network is built by deploying sensor nodes in the environment. Sensors perform the monitoring task substituting human presence at the site. Sensor nodes are freely deployed in the real time environment. Sensor nodes work on in-built batteries because it's not possible to provide power in the real time scenarios. Sensor nodes are freely deployed in the network without any supervision...
Wireless sensor networks (WSN) needs a communication protocol that is very efficient in Energy to reduce the consumption of energy to the maximum. The energy, memory, processor, low range bandwidth and communication of the sensor nodes are taken as resource constrained. The fading and irregularity of radio in multi-hop cause are the unfavorable collision caused by WSN that reduces the sensor networks...
In Wireless Sensor Network (WSN) energy is the main concern while designing a WSN protocol. Clustering is one of the process to minimize the energy consumption in WSN. Local election of clustering head (CH) requires many communications such as hello message, advertising their chances and fuzzy logic process requires many CPU cycles, high power microcontrollers, high capacity of memories which increase...
The energy efficiency is one of the important factors to prolong wireless sensor networks (WSNs) lifetime. One way to achieve the energy efficiency is by minimizing the energy dissipation during event capturing i.e. sensing an event and during event transmitting.

Wireless Sensor Network (WSN) is an ad-hoc network consisting of sensor nodes having limited computational power fitted with a radio transceiver. Main constraint of a sensor node is the limitation of its energy resource in the form of a short battery life. Battery power conservation is very important in a sensor device since battery life is usually one of the critical componets in extending the life...
In recent development, the use of Wireless Sensor Network (WSN) to handle more complex functions is increasing drastically which in turns requires their powered battery sensors to efficiently utilise their energy in order to prolong the network lifetime for the heterogeneous nodes.

The main problem in Wireless Communication Networks in the field nodes is that the battery resources are constrained. In multi-hop network, if one of the nodes is switched off due to low battery power, the network is disconnected and the field information could be lost. While energy efficiency of communication protocols tries to ensure extended network lifetime, but battery drainage problem still...
Most current sensor nodes are composed of a microcontroller and a radio. Their real-time and peak performance would be a bottleneck when executing compute-intensive tasks. Several works demonstrate that adding a hardware co-processor could accelerate the execution speed of the sensor nodes. So far, no simulators can simulate these new sensor nodes in wireless networks. An extension to SUNSHINE [1],...
Automatic and real-time monitoring of the deformation and instability of slopes and crags is an effective means to predict landslide and other geological disasters.

The ZigBee-based WSN (Wireless Sensor Network) technology was used to real-time sample and...
Multiple Channel Design (MCD) has been adopted widely in wireless networks to increase throughput and reliability with relatively less energy consumption. Due to physical restrictions of sensor nodes, applying multiple radio channels in sensor networks poses significant challenges, particularly on energy consumption.
