A new and better geography based security routing protocol for wireless sensor networks

We propose a secure routing protocol for wireless sensor networks based on geographical position, which we believe its new and better; it borrows the idea of Geographic and Energy Aware Routing protocol and introduces security factor into the routing mechanism and it is explained in sections 1 and 2 of the full paper. Their core consists of: The criteria of routing choice are related to distance, energy and security, and the keys shared between any two nodes are distributed by key pre-distribution scheme using hexagon deployment knowledge, by which the mechanism of data transfers can be established. It can ensure the security, integrity and freshness for communication data. Some network attacks can be resolved with assistance mechanism. The protocol we presented can resist network attacks efficiently. The simulation results, presented in Figs. 3, 4, and 5, indicate preliminarily that the new protocol can achieve better energy utilization and longer network lifetime as compared with the existing geographical protocols.
