Processor-Sharing Queues and Resource Sharing in Wireless LANs
ثبت نشده
چکیده
In the past few decades, the processor-sharing (PS) model has received considerable attention in the queueing theory community and in the field of performance evaluation of computer and communication systems. The scarce resource is simultaneously shared among all users in these systems. PS models are used for modeling resource sharing mechanisms and have many applications in communication networks, as well as in logistics and manufacturing.

Law of Large Number Limits of Limited Processor-Sharing Queues
Motivated by applications in computer and communication systems, we consider a processor sharing queue where the number of jobs served is not larger than K. We propose a measure-valued fluid model for this limited processor sharing queue and show that there exists a unique associated fluid model solution. In addition, we show that this fluid model arises as the limit of a sequence of appropriat...
متن کاملDistributed Resources Management in Wireless LANs that Support Fault Tolerance
This chapter introduces a new radio resource management technique based on distributed dynamic channel assignment, and sharing load among Access Points (AP). Deploying wireless LANs (WLAN) at large scale is mainly affected by reliability, availability, fairness, scalability, and performance. These parameters will be a concern for most of managers who wanted to deploy WLANs. In order to address ...
متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...

متن کاملAsymptotic behavior of generalized processor sharing queues under subexponential assumptions
We analyze the behavior of Generalized Processor Sharing (GPS) queues with heavy-tailed service times. We compute the exact tail asymptotics of the stationary workload of an individual class and give new conditions for reduced-load equivalence and induced burstiness to hold. We also show that both phenomena can occur simultaneously. Our proofs rely on the single big event theorem and new fluid ...
