摘要
在大规模部署的无人值守的无线传感器网络中,节点很容易被俘虏,被俘虏的节点很可能伪造数据。如果不对其进行检测、过滤,伪造的数据最后就会被转发到基站。提出了一种基于地理位置的过滤伪造数据包的方案,每个节点只负责对一定区域内的节点收集的数据进行认证。最后在基于地理位置的路由协议GPSR中进行了实验,实验表明,目标和基站之间的距离在一定范围内,该方案经过2.5跳可以过滤80%的伪造数据包。
In a large-scale and self-service wireless sensor networks, sensor nodes are subjected to be compromised, and the comprised nodes can be used to fabricate data. If the bogus data are not checked and filtered, the bogus data will forward to the base station. This paper proposed a scheme filtering the fabricated data based on geographic location. Every node is responsible to authenticate the data which is collected by nodes in a certain region. Finally, the simulations are done based on the geographic routing protocol-GPSR, and the results show that if the distance between object and base station in a certain range, it can drop up to 80% of bogus data within 2.5 hops.
