    It is important to design on-chip crossbar by using appropriate traffic model. A kind of ¿4-high-1-low¿ traffic model is presented based on analysis of the character of unbalanced traffic among input port and output port of on-chip crossbar in 2D-Mesh NOC. Then it is analyzed how the performance of on-chip crossbar is impacted by ¿4-high-1-low¿ traffic model according to simulation. The impact... View full abstract»

  • A New Stability Criterion of Networked Control Systems

    Publication Year: 2009, Page(s):15 - 19
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB) | HTML iconHTML

    This paper concerns with robust stability criteria of networked control systems (NCSs) with the effects of both the time-varying network-induced delay and data packet dropout taken into consideration. A less conservative delay-dependent stability condition is formulated in the form of a linear matrix inequality based on a Lyapunov-Krasovskii functional. No slack matrix variables are introduced and... View full abstract»

  • A New Stability Criterion of Fuzzy Systems with Interval Time-varying Delay

    Publication Year: 2009, Page(s):20 - 23
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (262 KB) | HTML iconHTML

    The problem of the stability of fuzzy systems with interval time-varying delay is addressed. The time-delay is assumed to belong to a given interval. The systems are approximated by Takagi-Sugeno(T-S)fuzzy models with interval time-varying delay. A Lyapunov-Krasovskii functional, which is based on both the lower and upper bounds of interval time-varying delay, is proposed to derive a less conserva... View full abstract»

    The GPS system is capable of the one-way communication (OWC) transmitting non-navigational information if the reserved bits of L1C Nav message and the newly-added CNav message types for L2C signal are utilized. Excluding the potential communication protocol overheads, a single frequency with one satellite transmits data at 0.5B/s; with the dual frequency transmission by using L1C and L2C frequenci...

    One of the most important parameters in a wireless system is Bit Error Rate (BER). Hence in this paper we present a new system in which BER is lower than the other similar systems such as MC-CDMA, TH-MC-CDMA. In this paper, we describe the suggested system and analyse the BER for a flat fading channel with additive white Gaussian noise (AWGN). View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (349 KB) | HTML iconHTML

    Mobile ad hoc networks usually consist of mobile battery operated computing devices that communicate over the wireless medium and they have limited battery capacity. Many proposed routing protocols for mobile ad hoc networks concentrate on issues like the packet delivery ratio, routing overhead and shortest path between source and destination. In fact, power constraints represent an equally import... View full abstract»

  • Adaptive Routing In Ad Hoc Wireless Networks Using Ant Colony Optimization

    Publication Year: 2009, Page(s):40 - 45
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (431 KB) | HTML iconHTML

    This paper presents a new adaptive and dynamic routing algorithm called AAODV for mobile ad hoc networks inspired by Ant Colony Optimization algorithms. This algorithm is proposed by maintaining the nature of the Ad hoc On-demand Distance Vector (AODV) routing through the use of Ant Colony Optimization. AAODV maintains the on-demand nature of AODV but works in an adaptive manner. It does not send ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (308 KB) | HTML iconHTML

    One of the main parts of peer-to-peer multicast is the structure of overlay network. Most of the existing works utilize some common parameters for constructing overlay tree. These parameters are bandwidth and delay. The mismatch between current overlay structure and underlying network topology causes severe link stress and then leads to high end to end latency. According to these problems, we prop... View full abstract»
