A Geographic-location-information-based Secure Multicast Routing Protocol in Wireless Sensor Networks
Wei Wang · 2011
The paper proposes a geographic-location-information-based secure multicast routing protocol in wireless sensor networks for the traditional secure multicast routing protocol not applying to multicast communications.Basic random key scheme model has been proposed to distribute key among nodes of wireless sensor networks,and the geographic location information is used to build the virtual Steiner tree by which the secure multicast routing protocol is built.The security of this protocol has been analyzed by the multicast tree generation algorithm.The results show that the protocol enables each node share a symmetric key with its neighbor nodes,to stop the false nodes involved in the routing process for the purpose of establishing a secure multicast tree.
