Design and Development of Trust Based Approach to Mitigate Various Attacks in Mobile Ad-hoc Network

Mobile ad-hoc network (MANET) is used widely today. The work of MANET is totally depends on the cooperation of various nodes in the network. As we compared with the wired network, wireless network has various advantages, such as MANET doesn’t require any infrastructure; it is decentralized system and dynamic in nature. Hence MANET is popular in various areas such as Military application, wireless sensor network, Public network and more. But these advantages of MANET may become disadvantages: As its openness, decentralized and dynamic nature, it is highly prone to various attacks. That’s why security is the challenging job in MANET. Various existing system for detection of attacks is in-efficient and may require more computation and space as in cryptography technique. In this paper, the focus is given on the Trust based approach to mitigate the attack. In Trust based approach, the most trusted path is selected rather than the shortest path
