摘要：MANET (Mobile Ad hoc Network) is the self configuring t ype of network in which mobile nodes can join or leave the network when they want as it is a decentralized type of network. Du e to these unique properties of the MANET, it is much vulnerable to security attacks. ALARM protocol (Anonymous Location Aided Routing in MANET) is used in MANET to achieve the key securit y objectives, i.e. confidentiality, authentication, authorization, i ntegrity. ALARM protocol is based on certain assumptions, such as, location of the mobile nodes, time at each no de, range of mobile nodes etc. A ccording to time assumption, clocks of the mobile nodes are weakly synchronized. Due to this weak synchronizatio n of the mobile nodes replay attack is possible which degrades the reliability of the ALARM protocol. In this paper, we review the ALARM protocol, identify the problem related to time assumption of the ALARM protocol and propose a robust mechanism to isola te replay attacks in MANET
