A Secure Routing Protocol under Eavesdropping using SPENA Scheme?

In a wireless sensor network, an important problem is to provide privacy to the detecting sensor node and integrity to the data gathered by a node. In addition to the reliability, communication security is another important concern in wireless networks, since the wireless transmission is highly vulnerable to eavesdropping attacks due to the open nature of wireless medium. In eavesdropping we introduce transmission scheme; all relay and best relay and analysed the intercept behavior in wireless networks. Here we introduce a secure protocol TinyPK and TinySec which prevent from eavesdropping attack. Here we present a scheme to hide source information. The packet is modified en route by dynamically selected nodes to make it difficult for a malicious entity to trace back the packet to a source node and also prevent packet spoofing. Evaluating the proposed work through both simulation and analysis, we show proposed protocol can significantly outperform the closest routing protocol and security mechanism.
