Abstract

There are several usages for wireless sensor networks in military, supervisory, region considering, physiology, etc. Sensor nodes are usually equipped with some non chargeable batteries having limitations in lifetime while they cannot be replaced with other sensors when they fail. Each sensor has a failure probability which is affected from some factors like electrical energy, hardware failures, communication error, undesired environment situations, etc. Thus, fault tolerant is a very important and critical factor in such networks. Hardware redundancies like having redundant nodes and paths are suitable echniques used for increasing fault tolerant factor. On the other hand, using hardware redundancies leads increasing in overall network consumption because of using more number of sensors. In this paper we estimate the affect of redundancy on the number of correct responses that wireless sensor networks have on the received queries and also show the level of redundancy needed in different network conditions like having different fault probabilities and needed clusters to response the received queries. Keywords: wireless sensor network, fault tolerance, redundancy, reliability
