Performance study of a secure routing protocol in wireless mobile ad hoc networks

Mobile Ad Hoc Network (MANET) is a special type of mobile wireless network where a collection of mobile devices form a temporary network without any aid of an established infrastructure. Security issues put special challenges in MANET routing protocol design. This paper focuses on the performance study for security of a MANET routing protocol, and particularly on the improvement of the security for Dynamic Source Routing Protocol (DSR). We improve the security of routing for the existing DSR protocol by enhancing the concept of trust value, the selection of a secure route will be based on these trust values. ns-2 simulations are performed to evaluate the impact of applying trust value based route selection to the DSR protocol.
