Innovations in wireless sensor networks (WSNs) have dramatically expanded the applicability of control technology in day-to-day life, by enabling the cost-effective deployment of large scale sensor-actuator systems. In this paper, we discuss the issues and challenges involved in deploying control-oriented applications over unreliable, resource-constrained WSNs, and describe the design of our pl...

Time to deployment for wireless sensor networks could be reduced by using commercial sensor nodes. However, this may lead to suboptimal flexibility, power consumption and cost of the system. Our pilot deployment for precision agriculture and fruit growing research showed similar conclusions and outlined the design decisions leading to SADmote: a new sensor node for environmental monitoring. It ...

This letter proposes a novel mobile sensor deployment scheme for maximizing coverage. The basic idea is to force mobile sensors to move to predetermined target points that are the optimal layout in a distributed manner using Voronoi diagram data structure. A simulation shows that the result of the proposed scheme is quite close to the optimal result and outperforms previous works. key words: mo...

Wireless sensor networks are subject to failures. Deployment planning should ensure that when a sink or sensor node fails, the remaining network can still be connected, and so may require placing multiple sinks and relay nodes in addition to sensors. For network performance requirements, there may also be path-length constraints for each sensor node. We propose two local search algorithms, GRAS...

This paper reviews some of the recent advances in the development of algorithms for wireless sensor networks. We focus on sensor deployment and coverage, routing and sensor fusion.

Because of application requirements or hardware designs, sensor nodes may possess sector-like coverage. On the other hand, with some machinery such as stepper motors, these sensor nodes can spin to cover the objects around them. We call such sensor nodes the spinning, directional (SD) sensors. In the paper, we consider the SD sensor deployment problem, which decides how to deploy the minimum nu...

Rapid progress made in the field of sensor technology, wireless communication, and computer networks in recent past, led to the development of wireless Ad-hoc sensor networks, consisting of small, low-cost sensors, which can monitor wide and remote areas with precision and liveliness unseen to the date without the intervention of a human operator. This work comes up with a stochastic model for ...

In order to monitor for traffic traversal, sensors can be deployed to perform collaborative target detection. Such a sensor network achieves a certain level of detection performance with the associated costs of deployment and routing protocol. This paper addresses these two points of sensor deployment and routing algorithm in the situation where the absolute quantity of sensors or total energy ...

In this paper the importance of tool-suite for large scale Wireless Sensor Network (WSN) deployment scenario has been investigated. This tool-suite is classified depending on the required feature for WSN deployment. Here both pre-deployment and post deployment has been considered for classification. Planning tool is used in pre-deployment phase and diagnostic tool is used in post-deployment pha...

Traditional sensor nodes are usually battery powered, and the limited battery power constrains the overall lifespan of the sensors. Recently, wireless power transmission technology has been applied in wireless sensor networks (WSNs) to transmit wireless power from the chargers to the sensor nodes and solve the limited battery power problem. The combination of wireless sensors and wireless charg...
