Abstract
To solve the safety problem existed in geographic and energy aware routing protocol (GEAR), a security geographic and energy aware routing protocol (S-GEAR) was proposed. S-GEAR obtains the preferable safety feature by adding region division, key distribute scheme based on location, reputation evaluation mechanism based on multi-point confirm to GEAR, and can withstand a variety of attacks of network layer. The simulation result shows that S-GEAR has capacity to identify malicious nodes, and has better security level than GEAR in terms of packet delivery ratio and drop ratio while there exists attacking nodes.
