We studied the problem of sequentially testing M ≥ 2 hypotheses with a decentralized sensor network system. In such a system, the local sensors observe raw data and then send quantized observations to a fusion center, which makes a final decision regarding hypothesis is true. Motivated by the two-stage tests in Wang and Mei (2011), we propose a multistage decentralized sequential test that prov...

Shale gas represents a major fraction of the proven reserves of natural gas in the United States and a collection of other countries. Higher gas prices and the need for cleaner fuels provides motivation for commercializing shale gas deposits even though the cost is substantially higher than traditional gas deposits. Recent advances in horizontal drilling and multistage hydraulic fracturing, whi...

In this paper, we present experimental data indicating that multistage interconnection networks with randomly positioned wires are likely to be substantially better for message routing applications than traditional multistage networks such as the butterfly. Data is presented for a variety of routing models, including storeand-forward routing, cut-through routing, and circuit switching, as well ...

An interconnection network system consists of layers of switching elements connected together in a predefined topology providing the connectivity between the set of processors and the set of memory modules. Performance analysis of a network system is important as it determines the usability and the efficiency of the network to provide services. A shuffle-exchange network (SEN), a specific type ...

The sliding-banyan (SB) network employs an interleaved multistage shuffle-exchange topology, implemented with a three-dimensional free-space interconnection architecture that connects a multichip backplane to itself. Surface-normal emitters and detectors, which compose the stages' input-output, are spatially multiplexed within the same chip location, along with electronic control and switching ...

Multistage interconnection networks (Banyan networks) are frequently used for performance evaluation of communication systems (e.g. Ethernet and ATM switches). There exist several studies (see [9] and [7]) describing the performance of networks in which packets (or frames) are unicasted (i.e. one switching element (SE) sends the packet to one and only one other SE). A model for MINs in case of ...

Call packing has been recognized as a routing scheme thatsignificantly reduces the blocking probability of connection requests ina circuit-switched Clos multistage interconnection network. In this briefcontribution, for the first time, we develop general analytical models forthe point-to-point blocking probability of the call-packing scheme appliedto Clos networks. By introd...
