Congestion management is likely to become a critical issue in interconnection networks, as increasing power consumption and cost concerns lead to improvements in the efficiency of network resources. In previous configurations, networks were usually oversized and underutilized. In a smaller network, however, contention is more likely to occur and blocked packets cause head-of-line (HoL) blocking among...
Design constraints imposed by global interconnect delays as well as limitations in integration of disparate technologies make 3D chip stacks an enticing technology solution for massively integrated electronic systems. The scarcity of vertical interconnects however imposes special constraints on the design of the communication architecture. This article examines the performance and scalability of different...
This paper examines the performance of segregate networks with single and multiple channels. It compares the simulation results to the location-aware channel assignment protocol named GRID. The term segregated means that the network is divided into smaller domains and each one operates on different radios. Each node is assigned a predefined pool of radios, per segregate. The results show that the...
Due to their popularity, dense deployments of wireless local area networks (WLANs) are becoming a common feature of many cities around the world. However, with only a limited number of channels available, the problem of increased interference can severely degrade the performance of WLANs if an effective channel assignment scheme is not employed. Previous studies on channel assignment in WLANs almost...
We consider a queueing network in which there are constraints on which queues may be served simultaneously. Such networks, called ldquoswitched networksrdquo [3] can be used to model input-queued switches, wireless networks, or bandwidth sharing in the Internet. The scheduling algorithm for such a network specifies which queues to serve at any point in time. The performance of scheduling algorithm...
