Fault Tolerant Three Dimensional Environment Monitoring using Wireless Sensor Networks

One important application for wireless sensor networks is environment monitoring, which may include military facility security monitoring, industrial working field monitoring or wildfire monitoring. Fault tolerance is one of the primary objectives of current research for the environment monitoring oriented sensor network. To ensure the fault tolerance of the monitoring task in the three-dimensional settings, one way is to provide safe modes using redundancy. Beside redundancy, the sensor network deployment method is also an important factor to fault tolerance. In this paper, we investigate the relationship between fault tolerance and the randomness of deployment methods and examine the tradeoff between the sensor network lifetime and the equipment cost
