Enhancement in Ad hoc on Demand Distance Vector （AODV） Routing Protocol Security

IntroductionAs mobile ad hoc networks edge closer toward wide-spread deployment ,security issues have become a centralconcern and are increasingly i mportant . Due to thedecentralized nature of ad-hoc networks , securityrequirements are different from those of traditionalnetworks . Problems are caused for example by the weakphysical protection of the network nodes , the inherentinsecurity of the wireless communication channel , themobility of the nodes and their li mited processor andbattery r…

Enhancement in Ad hoc on Demand Distance Vector (AODV) Routing Protocol Security

Ad-hoc networking has mainly been associated with military battlefield networks. 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.
