While cooperative communication has many benefits and is expected to play an important role in future wireless networks, many challenges are still unsolved. Previous research has developed different relaying strategies for cooperative multiple access channels (CMA), cooperative multiple relay channels (CMR) and cooperative broadcast channels (CBC). However, there lacks a unifying strategy that ...

To successfully apply evolutionary algorithms to the solution of increasingly complex problems we must develop effective techniques for evolving solutions in the form of interacting coadapted subcomponents. In this paper we present an architecture which involves cooperative coevolution of two subcomponents: a genetic program and an evolution strategy. As main difference with work previously don...

We study a simple pursuit scenario in which the pursuer has potential access to an additional off-board global sensor. However, the global sensor can be used for either of two purposes: to improve the state estimate of the pursuer, or to obtain more data about the trajectory being tracked. The problem is to determine the variation in the performance of the system as the global sensor changes it...

warranty as a kind of service contract today plays a role key in business and legal transactions. in this paper, we present a manufacturer, an agent and a customer's model under different service contracts suggestions. the manufacturer's profit is maximized by determining sale price, warranty period and warranty price. in addition we obtain optimal maintenance cost or repair cost for ...

To sense the spectrum efficiently in heterogeneous multi-channel and multi-user cognitive network, a parallel cooperative spectrum sensing strategy based on genetic algorithm is proposed. It defines the expression of system utility considering the transmission gain and sensing overhead, and protects the primary user network by introducing the penalty function. To obtain the largest system utili...

To address the negative impact of large-scale disorderly grid connection EVs on stable operation power grid, a cooperative game control strategy for based tariff leverage is proposed, taking grid-side and user-side economy as objective function, into account EV load state constraint, distribution bi-directional charging discharging pile dynamic members’ revenue constraint. A model piles establi...
