中文摘要：
在无线传感器网络中，基于地理位置的路由协议面临着选择性转发攻击的威胁，针对GPSR（GreedyPerimeterState—lessRouting）和GEAR（GeographiealandEnergyAwareRouting）协议存在的问题，设计了一种用于验证节点的方案，将节点的实际地理位置信息与接收信号强度指示信息相比较，用以验证节点的可靠性，仿真实验表明，有效避免了sinkhole攻击（槽洞攻击）和wormhole攻击（虫洞攻击），进一步提高了网络的安全性。
英文摘要：
In Wireless Sensor Networks, location-based routing protocols are faced with the threat of selec- tive attacks. In view of the problems of GPSR（Greedy Perimeter Stateless Routing）and GEAR（Geographicaland Energy Aware Routing）protrcols,it designed a project used to validate the node. It will have the actual geographical location information of nodes,compared with the RSSI information of nodes to verify the reliability. Simulation results show that an effective attack avoids the sinkhole （slot-hole attack） and the wormhole attack（wormhole attack）to further enhance the security of the network.
