This article presents an approach for deriving upper bound for endto-end delay in a double star switched Ethernet network. Four traffic classes, following a strict priority queuing policy, were considered. The theoretical analysis was based on network calculus. An experimental setup, which accurately reflects an automotive communication network, was implemented in order to evaluate the theoreti...

3G Radio Access Networks (RANs) generally have to transport traffic with a variety of heterogeneous Quality of Service (QoS) requirements. In today’s 3G RANs, Asynchronous Transfer Mode (ATM) technology is used to provide the desired QoS. However, packet based RANs have been subject to recent standardization. In this case, Differentiated Services can be deployed to offer the required QoS using ...

Most of the sensor network applications need real time communication and the need for deadline aware real time communication is becoming eminent in these applications. These applications have different dead line requirements also. The real time applications of wireless sensor networks are bandwidth sensitive and need higher share of bandwidth for higher priority data to meet the dead line requi...

Based on queuing theory we develop an analytical approximation for low and high priority packet delays in a Spatial Reuse Protocol (SRP) ring.

The paper presents an analytical model for the performance evaluation of IEEE 802.11e EDCA scheme under finite load conditions on the basis of various instances of delay metric (i.e., media access delay, queuing delay and total delay). The simulation results show that the analytical estimated instances of the delay metric are almost accurate. The paper exhibits that concerning the delay of serv...

This article investigates the problem of the quality of service decrease in CARNet network during high videoconferencing traffic. The main objective of this research is to apply different queuing methods, i.e. FIFO, Priority Queuing and Weighted Fair Queuing on the proposed network. The ultimate objective is to create a model for the quality of service performance measurement based on the CARNe...

While the modern graphics processing unit (GPU) offers massive parallel compute power, the ability to influence the scheduling of these immense resources is severely limited. Therefore, the GPU is widely considered to be only suitable as an externally controlled co-processor for homogeneous workloads which greatly restricts the potential applications of GPU computing. To address this issue, we ...

Despite the greater bandwidth available for home Internet users, network problems continue to surface with regard to the mix of network applications being run. The ease in which Internet sharing can be configured, coupled with the increase in the number of computers present in consumer residences, increase the likelihood that concurrent network applications will have to compete for access to a ...
