Secure data transmission on MANET by hybrid cryptography technique

Mobile Ad-hoc Network (MANET) is special types of mobile wireless network where the groups of mobile devices form a temporary network without any kind of an infrastructure. It is very usefully due to its self maintenance, self organizing and by reason of mobility of wireless communication. Two major issues are found in such kind of network performance and security. In mobile ad-hoc network there are so many attacks which reduced the performance of network. In this paper we have focus only active attacks in network layer. Ad Hoc On-Demand Vector Routing protocol is a reactive routing protocol for ad hoc networks that maintain routes only between nodes which want to communicate by using routing messages. AODV provide loop free routes during link breakages. SAODV is a secure routing protocol based on trust model for mobile ad-hoc network. For provide security and increase performance in MANET, we have applied SAODV protocol and our solution uses Hybrid Cryptography Technique (DES, RSA Algorithms) on SAODV. This paper presents comparison based on simulation of AODV, SAODV routing protocol of MANET with Different parameters like energy, packet delivery ratio and throughput. The proposed cryptographic routing algorithm is implemented through the NS2 network simulation environment. The outcome of our proposed method the energy is low; packet delivery ratio and throughput are high as compare to traditional method.
