Multi-Path Security-Aware Routing Protocol Mechanism for Ad Hoc Network

The existing SAR (security aware routing) protocol is an ad hoc network protocol that finds a secure path using the security level of mobile nodes. However, the SAR protocol sometimes transfers data through inefficient transmission paths because It always tries to find secure nodes for a safe transmission. Since it is a protocol based on AODV, the new routing path is searched from the very beginning when a transmission fails. Obviously it cause transmission delay Also during the new routing path search, the connection could not established when the security level of intermediate node is lower than the level requested by a source node. In this paper, MP-SAR (multi-path SAR) is suggested to improve the SAR protocol. MP-SAR maintains data confidentially offered by SAR, and it is a multiple security path discovery algorithm that can transfer data quickly and reliably by using the shortest efficient path among multi-paths
