We consider the transmission power control problem with SINR as objective function in the two scenarii: selfish and cooperative. We show that in the selfish (non-cooperative) scenario several Nash equilibria can arise. In particular, the game can take the form of the HawkDove game, where the users can choose either conciliation or conflict fighting for shared sub-carriers. We fully characterize...

The GM-MDS conjecture of Dau et al. (ISIT 2014) speculates that the MDS condition, which guarantees the existence of MDS matrices with a prescribed set of zeros over large fields, is in fact sufficient for existence of such matrices over small fields. We prove this conjecture.

Cooperative (spectrum) sensing is a key function for dynamic spectrum access and is essential for avoiding interference with licensed primary users and identifying spectrum holes. A promising approach for effective cooperative sensing over a large geographic region is to rely on special spectrum-sensing providers (SSPs), which outsource spectrum-sensing tasks to distributed mobile users. Its fe...

Cooperative applications need proper transactional support for coordinating joint activities, sharing of data, and semantically correct exchange of information of collaborating users. Conventional transaction models based on the ACID properties do not meet the typical requirements of cooperative applications. The CoAct model [27] is designed for supporting cooperative work in multi-user environ...

A full-duplex non-orthogonal multiple access (FD-NOMA) systems are expected to play a significant role in fifth generation (5G) networks, addressing spectrum efficiency and massive connections. In this regard, the feasibility of FD communications improve utilization is main consideration term outage performance. Specifically, we derive exact formulas probability for FD-NOMA, over Nakagami-m fad...

The paper studies the routing in the network shared by several users. Each user seeks to optimize either its own performance or some combination between its own performance and that of other users, by controlling the routing of its given flow demand. We parameterize the degree of cooperation which allows to cover the fully non-cooperative behavior, the fully cooperative behavior, and even more,...

Conventional transaction models based on the ACID properties do not meet the typical requirements of cooperative applications.

Cooperative work enables a users group to collaborate in the same project. The use of a cooperative database system enables distributed users to cooperate on large data volumes. We modelize the cooperative work by alternative versions which belong to each participant, and a merge mechanism which is controled by a group supervisor. This model is a variant of the distributed architecture model, c...

Beneficiaries of common pool resources (CPRs) may select available noncooperative and regulatory exogenous institutions for managing the resource, as well as cooperative management institutions. All these institutions may increase the longterm gains, prolong the life of the resource, and help to escape the tragedy of the commons’ trap. Cooperative game theory approaches can serve as the backbon...
