چکیده
Résumé Les techniques de communication coopérative ont connu récemment un large intérêt dans la communauté de recherche vu les grands avantages qu’elles pourraient apporter en termes de performance et de débit. Le principe de base des communications est fondé sur l’utilisation d’un relai entre la source (émetteur) et la destination (récepteur). Dans ce papier, on propose une adaptation de l’allocation des ressources dans les relais afin de profiter au maximum de ces techniques. Plus particulièrement, on est intéressé à la situation des mobiles en bordure de cellule dans un contexte multicellulaire. Dans ce contexte, les mobiles pourraient demander plusieurs types de services avec plusieurs priorités mais avec des conditions difficiles du canal de transmission. En utilisant une allocation adaptative de ressources et une optimisation intercouche, on démontre qu’on peut assurer les contraintes de priorité et de performance (application temps réel) requises par les mobiles en bordure de cellule.

Performance Study of Untrusted Relay Network Utilizing Cooperative Jammer
Abstract—In this paper, the problem of secure transmission in two-hop amplify-and-forward (AF) systems with an untrusted relay is investigated. To prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the destination-based cooperative jamming (DBCJ) technique is used. In this method the destination sends an intended jamming signal to the relay. T...
متن کاملAdaptive call admission control and resource allocation in multi server wireless/cellular network
The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adj...
متن کاملResource Allocation for a Cooperative Broadband MIMO-OFDM System
In this chapter, a cooperative broadband relay-based resource allocation technique is proposed for adaptive bit and power loading multiple-input-multiple-output/orthogonal frequency division multiplexing (MIMO-OFDM) system. In this technique, sub-channels allocation, M-QAM modulation order, and power distribution among different sub-channels in the relay-based MIMO-OFDM system are jointly optim...
متن کاملDetermination of optimal and and water allocation under limited water resources using soil water balance in Ordibehesht canal of Doroodzan water district
ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...
