Robust Location Aware Wormhole Detection Technique for Wireless Sensor Network

The Wireless Sensor Networks are typically deployed in ubiquitous and pervasive applications that make them susceptible to various forms of security attacks. In addition, due to the limited battery capacity, processing and memory powered sensor nodes make it difficult to devise the security protocols that are inherently resource intensive. Due to lack of security, nodes tend to get compromised by the adversaries. These nodes attract the data towards itself and either modifies the data and denies forwarding it. This paper ensures that the sensor network is secure to large extend by eliminating the compromised nodes. One of the potent forms of attacks is the Wormhole attacks - a Denial of Service attack on the network layer. Wormhole attacks enable an attacker with limited resources and no cryptographic material to disrupt wireless networks. In wormhole attack, an attacker records packet at one location in the network, tunnels them (possibly selectively) to another location and retransmits them there into the network. In this paper, present an algorithm for detecting wormhole attacks in wireless sensor network.
