Abstract
Mobile Ad hoc NETworks (MANETs) are networks in which mobile routers are connected via wireless links forming dynamic topologies.They are self organizing and autonomous networks, consisting of mobile nodes that act as routers and collaborate with one another to form a network. A Monitor for Mobile ad Hoc networks (MMAN)can be a solution for dynamic assessment of individual node cooperation in forwarding packets for their neighbors, which helps identify selfish and malicious nodes in a MANET. Selfishness Selfishnessis a behaviour where a node or a group of nodes in a MANET refuses to forward their peersâ„¢ packets, could significantly affect the performance of a MANET. Solution Behavior-based solutions have been proposed to detect selfish or malicious behavior in the network which is an approach that tend to be suited to the self-organized nature of a MANET as nodes evaluate the behavior of their peers, share their evaluations, and dynamically adjust their own behavior. When a particular node is a non-cooperative one, all other members of the network avoid requesting or providing services from and to the misbehaving or selfish node. Requirements: This system require either secure hardware or a tamper-proof software suite to be installed on all network nodes.Besides, to monitor and report misbehavior, nodes have to consume their CPU power,battery, and bandwidth. MMAN relies on multiple monitoring stations that collaborate and combine information to maintain an accurate and up-to-date view.Many Monitoring Units (MUs) are deployed throughout the MANET which are responsible for collecting information regarding network behavior.The information collected by the MUs is delivered to management nodes, where they are analyzed and presented on a GUI. With MMAN, detecting selfishness is very robust under high-volume traffic. Detailed seminar report download: MANET- selfishness detedction.pdf (Size: 420 KB / Downloads: 425)

Watchdog’s principles Based on the promiscuous mode monitoring and implemented with a source routing protocol. When a node Na sends a packet to Nb to forward to Nc, it monitors it by simply overhearing the channel, it validates the forwarding iff it overhears the packet retransmitted by Nb. This process is generated for each couple of hops in the route |
