Performance Analysis of Observation Based Cooperation Enforcement in Ad Hoc Networks

Analysis of coalition formation and cooperation strategies in mobile ad hoc networks

This paper focuses on the formal assessment of the properties of cooperation enforcement mechanisms used to detect and prevent selfish behavior of nodes forming a mobile ad hoc network. In the first part, we demonstrate the requirement for a cooperation enforcement mechanism using cooperative game theory that allows us to determine a lower bound on the size of coalitions of cooperating nodes. I...

Observation-based Cooperation Enforcement in Ad Hoc Networks

Ad hoc networks rely on the cooperation of the nodes participating in the network to forward packets for each other. A node may decide not to cooperate to save its resources while still using the network to relay its traffic. If too many nodes exhibit this behavior, network performance degrades and cooperating nodes may find themselves unfairly loaded. Most previous efforts to counter this beha...

RTC: A Reputation-based Technique for Cooperation Enforcement in Ad Hoc Networks based on TCP Congestion Control Mechanism

Multihop ad hoc networks were designed assuming trustworthiness and cooperation between all participating nodes; nodes in an ad-hoc network rely on one another in packet forwarding, detecting routes, etc. Thus, the performance of an ad hoc network degrades considerably with the presence of misbehaving nodes. Nodes’ misbehaviour includes, but is not limited to, refusing to relay data packets, co...

Cooperation enforcement schemes for MANETs: a survey

The employment of adequate trust methods in mobile ad hoc networks (MANET) has been receiving increasing attention during the last few years, and several trust and security establishment solutions that rely on cryptographic and hashing schemes have been proposed. These schemes, although effective, produce significant processing and communication overheads and consume energy, and, hence, they do...
