Middleware is the software layer that lies between applications and the devices, which make diverse vehicles exchange information transparently in Vehicular Ad Hoc Network (VANET). And the useful information can be seen as services which include web surfing, coordinated braking, runway incursion prevention, adaptive traffic control and many others. In this paper, we focus on discovering the optimal...
This paper presents an active QoS infrastructure of wireless sensor networks (WSN), named QISM, which is based on middleware and service-oriented. The design, structure, important modules and working processes are discussed. The important characteristics of QISM include the active regulation mechanism based on feedback and negotiation between applications and network, the architecture based on middleware...
In this paper different methods of QoS computing are described. The known QoS parameters and present classification of QoS parameters are described. The computation particularity of different types of GRID services is explained. The differences of GRID network parameters influence using different Middleware are presented.
Providing guaranteed QoS for grid services using resource reservation and allocation is an important feature for today's service grid. Reservation requests with existing mechanisms are often rejected during the resource utilization peak and lead to resource capacity fragment problem. In this paper, we propose a flexible capacity reservation mechanism, called FIRST, which employs the slack time-enabled...
