Method Based on Triangulation for Sensor Deployment on 3D Surfaces
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 ...
Average Error Probability in Wireless Sensor Networks With Imperfect Sensing and Communication for Different Decision Rules
(Ieee-inst Electrical Electronics Engineers Inc, 2016-05-15)
This paper presents a framework to evaluate the probability that a decision error event occurs in wireless sensor networks, including sensing and communication errors. We consider a scenario where sensors need to identify ...
ZigBee Wireless Dynamic Sensor Networks: Feasibility Analysis and Implementation Guide
(Ieee-inst Electrical Electronics Engineers Inc, 2016-06-01)
The wireless sensor network (WSN) technology has attracted increasing attention considering its potential in many application fields. In most studies on WSNs, the network is assumed to cover several static devices over a ...
Human-centric wireless sensor networks to improve information availability during urban search and rescue activities
When a natural disaster hits an urban area, the first 72 h after are the most critical. After that period the probability of finding survivors falls dramatically, therefore the search and rescue activities in that area must ...
