Efficient Energy Maximizing and Clone Detection using Wireless Sensor Network

Compromised node and denial of service are two key attacks in wireless sensor networks (WSNs). Wireless sensors have been widely deployed for a variety of applications, ranging from environment monitoring to telemedicine and objects tracking, etc. For cost effective sensor placement, sensors are usually not tamperproof devices and are deployed in places without monitoring and protection, which make them prone to different attack-s. Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. The energy consumption of Gossip Crypt is lower than a public-key based solution by several orders of magnitude. In this paper, we propose a location-aware clone detection protocol, which guarantees successful clone attack detection and has little negative impact on the network lifetime. . Like in all shared-medium networks, medium access control (MAC) is an important technique that enables the successful operation of the network. One fundamental task of the MAC protocol is to avoid collisions from interfering nodes. There are many MAC protocols that have been developed for wireless voice and data communication networks. The ring structure facilitates energy efficient data forwarding along the path towards the witnesses and the sink.
