Dependable Wireless Sensor Networks by Dynamic Redundant Deployment
Nancy Alrajei · Journal of Communications Technology Electronics and Computer Science · 2019
It is essential for Wireless Sensor Networks (WSN) to be deployed in a dependable manner to extend the network life time and to stay functional as long as possible. Redundancy has always been the key ingredient used to provide Dependability. The concepts of k-connectivity have been used in the recent years to quantify this redundancy and fault tolerance and dependability. In this paper we analyze in depth the concept of dependability and its threats in WSN. Furthermore propose deployment algorithm based on redundancy. The redundancy is not uniform but concentrated around areas of the network that are either more vulnerable or whose failure is more consequential.
