Abstract
Problem statement: A Mobile Ad Hoc Network (MANET) is a self-created self-organized and self-administering set of nodes connected via wireless links without the aid of any fixed infrastructure or centralized administrator. Protecting the network layer from malicious attacks is an important and challenging issue in both wired and wireless networks and the issue becomes even more challenging in the case of MANET. Approach: In this study we propose an Umpiring System (US) that provides security for routing and data forwarding operations. We present three US models- Single (one) Umpiring System (SUS), Double Umpiring System (DUS) and Triple Umpiring System (TUS). In the umpiring system, each paricipating node of the system will have different roles to play; some of the nodes will be doing traditional operations of routing and packet forwarding, while some others will be monitoring the behaviour of designated nodes. If any misbehavior is noticed umpires immediately flag off the guildy node. Results: We find that. Throughput with single umpire system is greater than DUS and TUS. From throughput and energy point of view SUS is the best. But both false positives and false negatives are lower with TUS, indicating it is a better detection system. Conclusion: We envisage that our system can profitably be used in civilian situations where invariably nodes are lean and energy starved.

Summary
A Mobile Ad Hoc Network (MANET) is a selfcreated self-organized and self-administering set of nodes connected via wireless links without the aid of any fixed infrastructure or centralized administrator. MANET is ideally suited for potential applications in civil and military environments, such as responses to hurricane, Marti et al (2000) introduced two extensions to the Dynamic Source Routing Protocol DSR to mitigate the effect of routing misbehaviors-watchdog and pathrater. The watchdog identifies misbehaving nodes while the path rater avoids routing packets through these nodes. When a node forwards packets the node’s watchdog verifies that the node in the path forwards the packet. The watchdog does this by listening promiscuously to the hop transmissions. If the node doesn’t forward the packet it is misbehaving. The watchdog detects earthquake, tsunami, terrorism and battlefield the misbehavior and sends a message to the source, conditions. Security is an important aspect in such mission critical applications
