Abstract

In a near future, our use of computer technology will increasingly depend on Wireless Sensor Network (WSN) system consists of plethora of nodes. This WSN's survivability will depend most critically on base station that attaches WSN to outside network including Internet. The need for survivability is most pressing for mission critical systems. To increase the survivability, we show up the detection model with proactive rejuvenation and reactive recovery through a Continuous Time Markov Chain (CTMC) process, where it is designed to provide continued useful service in face of attacks, failures, or accidents and to prevent the intruders' attempts in their tracks. Afterwards, we focus on downtime analysis. This is a general model which can be applicable to any nodes in a WSN environment. But this model can be more critically used for base station since base station is almost a single point of failure in a WSN.
