In this paper, we develop a new distributed adaptive power control framework for multi-cell OFDM systems based on the game theory. A specific utility function is defined considering the users’ achieved average utility per power, i.e., power unit based utility. We solve the subcarrier allocation issue naturally as well as the power control. Each user tries to maximize its utility by adjusting th...

We present a cooperative, multistep negotiation mechanism for multiagent systems. This mechanism uses marginal utility gain and marginal utility cost to structure the negotiation process. This enables an agent to understand another agent’s situation in order to find a solution that increases their combined utility. These two values summarize the agent’s local information and reduce the communic...

In the present research, a multi-objective model is proposed, which considers equity among the citizens in addition to the cost criterion. Then, the model will be solved using Reservation Level Tchebycheff Procedure (RLTP), which is one of the interactive multi-objective decision-making techniques. Subsequently, the obtained results will be compared with those of the single-objective models to ...

Random utility models have been widely used in many diverse fields. Considering utility as a random variable opened many new analytical doors to researchers in explaining behavioral phenomena. Introducing and incorporating the random error term into the utility function had several reasons, including accounting for unobserved variables. This paper incorporates fuzziness into random utility mode...

While current research focuses on Enhanced 3 Generation and IMT-Advanced mobile systems, many advanced techniques are investigated by world-wide research institutes and standard organization, such as Multi-Input Multi-Output, Coordinated Multi-Point and coordinated multi-antenna cellular network architecture. Based on these novel techniques, the access control strategies also need to be develop...

Grid computing aggregates the power of widely distributed resources and provides non-trivial services to the users. Resource management and scheduling play a crucial role in Grid computing environment. It becomes more challenging in Utility Grids, where consumer wants to pay minimum amount and providers want to earn maximum amount. Many existing scheduling approaches are dedicated to either sin...

A new multiuser detector for direct-sequence codedivision multiple-access communication systems is described. The proposed detector divides the received signal stream into a number of overlapping windows and decorrelates them window by window. This scheme is justified by an analysis on the convergence and decay rate of the impulse response. Based on the results, a signaladapted criterion is dev...

There are two service selection strategies in dynamic service composition, i.e., global strategy and local strategy. The existed global service selection algorithms, due to insufficiently show users’ partiality and feature of the service, is unfavorable to encourage the service provider to optimize the service quality to some extent. In this paper, an ordinary utility function is used as a nume...
