Security attacks and their countermeasures along with node replication attack for time synchronization in wireless sensor network

Abstract

Wireless sensor network (WSN) is a group of interconnected sensor nodes, usually broaden out in areas which are not easily accessible and communicate wirelessly. A sensor node is capable to sense environment, communicate the gather information to another nodes and also have computing power. The use of ubiquitous wireless sensor networks has increased the complexity day by day to identify wireless sensor network attacks and there countermeasures. In this paper, different types of vulnerabilities associated with WSN and their effects, countermeasures are discussed.
