Abstract

MANET (Mobile Ad hoc Network) is the self configuring type of network in which mobile nodes can join or leave the network when they want as it is a decentralized type of network. Due 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 security objectives, i.e. confidentiality, authentication, authorization, integrity. ALARM protocol is based on certain assumptions, such as, location of the mobile nodes, time at each node, range of mobile nodes etc. According to time assumption, clocks of the mobile nodes are weakly synchronized. Due to this weak synchronization 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 isolate replay attacks in MANET.
