Security has received considerably less attention and the issue needs to be addressed before any successful applications will appear. Due to the insecure nature of the wireless link and their dynamically changing topology, wireless ad-hoc networks require a careful and security-oriented approach for designing routing protocols. In this paper, an AODV-based secure routing protocol- ENAODV is presented. A speed-optimized digital signature algorithm is integrated into the routing protocol. The protocol algorithm is implemented with NS-2. The security of the protocol is analyzed. The simulating results show that the performances of ENAODV protocol, such as average node energy consumption, packet delay and packet delivery is nearly the same as standard AODV protocol.展开更多

Local neighboring nodes collaboratively monitor each other and sustain each other.

We also analyze the storage, computation, and communication overhead of PNCSR, and provide a simple yet meaningful overhead comparison.
