A Review on Secure Routing in Wireless Sensor Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 7
Abstract
Sensor nodes are tiny, low-cost devices equipped with environment sensors and radio for wireless communication. These sensor nodes may constitute the network for monitoring physical phenomena. Such network is called Wireless Sensor Network (WSN). Wireless sensor network consists of high number (102-106) of sensor nodes. Wireless sensor networks can be utilized in a broad variety of applications ranging from battlefield surveillance in military, through remote patient monitoring in medicine to forest fire detection in environmental applications. Majority of WSN applications require at least some level of security. In order to achieve the needed level, secure and robust routing is necessary. Secure data transmission is a critical issue for wireless sensor networks (WSNs). In a cluster-based WSN (CWSN), every cluster has a leader sensor node, regarded as cluster head (CH). A CH aggregates the data collected by the leaf nodes (non-CH sensor nodes) in its cluster, and sends the aggregation to the base station (BS). In this paper, we have surveyed various security issues and their countermeasure to reduce these issues.
