We study a lattice model of “commons”, where a resource is shared locally among the agents of various cooperative tendency. The payoff function of an agent is proportional to the fraction of his operation rate and the net output of the resource. After each time step a site is occupied by the neighbor of maximum profit or by its owner himself. In steady state the model is dominated by “altruist”...

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...

In cooperative communication in wireless networks, selection of best relay node is an important task. And provide secure transmission is also a challenging work. Our proposed protocol provides a new approach for relay selection and secure transmission in cooperative network for wireless network. Secure and efficient relays are selected on the basis of RPI table that maintain RPI points which is...

Previous research on the Concealed Information Test indicates that knowledge of the critical information of a given event is sufficient for the elicitation of strong physiological reactions, thus facilitating detection by the test. Other factors that affect the test's efficacy are deceptive verbal responses to the test's questions and motivation of guilty examinees to avoid detection. In the pr...

This paper describes how to establish trust for P2P storage using a payment-based scheme. This scheme relies on the monitoring of storage peers on a regular basis. The verification operations allow assessing peer behavior and eventually estimating their subsequent remuneration or punishment. The periodic verification operations are used to enforce the fair exchange of a payment against effectiv...

The correct functioning of a peer-to-peer network relies on cooperative behavior of peers as service providers. Current approaches to detection and deterrence of non-cooperative behavior, such as reputation systems, rely on (1) global sharing of observations about service provisioning and (2) global authentication. These two factors severely impair the practical applicability. We propose a nove...

An important aim of the current research effort in artificial intelligence and robotics is to achieve cooperative agent behavior for teams of robots in real-world scenarios. Especially in the RoboCup scenario, but also in other projects like Nexus, agents have to cooperate efficiently to reach certain goals. In the RoboCup project, cooperative team-play and team strategies similar to real world...
