无线传感器网络中的安全GEAR路由协议

GEAR路由是无线传感器网络中一种高效的位置和能量感知的地理路由协议，在抵御路由攻击方面有较好的特性，但是GEAR路由不能抵御虚假路由、女巫、选择性转发等攻击。针对该问题，提出了一种适合无线传感器网络特征的、基于位置密钥对引导模型的安全GEAR路由协议SGEAR，并对该协议进行了性能分析，分析显示在较小的系统开销下，SGEAR能有效抑制上述攻击及DoS攻击。

Secure geographical and energy aware routing protocol in wireless sensor networks

Geographical and energy aware routing(GEAR) is an efficient routing protocol in wireless sensor networks(WSNs).It behaves well in the face of routing attacks,but it is incapable of defending against bogus routing information,sybil attack and selective forwarding.Aimed at this problem,this paper presents a location pairwise keys bootstrap scheme based on secure geographical and energy aware routing protocol(SGEAR).Then it gives the performance analyses of SGEAR,which shows that the scheme is efficient to(defend) against the attacks mentioned above and DoS attack.
