The evaluation of network system effectiveness is the key method to judge whether the system network architecture is stable and effective. This paper adopts the entropy method and the experience of decision makers to establish the evaluation system of the network efficiency of the intelligent distribution network monitoring service system, basing on the evaluation index of network effectiveness obtained...
This paper investigates the type-2 T-S fuzzy multiple feedback-loop guaranteed cost controller design for uncertain singular systems with transmission and state delays. Based on the type-2 T-S fuzzy theory, this work constructs a mathematical model for a class of nonlinear uncertain singular time-delay systems. Using the parallel distributed compensation concept with Lyapunov theory and linear matrix...
With the rapid growth of content-based network services, there is increasing interest in reducing the emissions associated with brown-energy consumption in Content Delivery Networks (CDNs). At the same time, content needs to be placed in safe Data Center (DC) locations, which are unlikely to be hit by disasters. Further risk reduction is achieved using content replication which provides inter-DC content...
In order to improve the throughput in cognitive radio networks (CRNs) without affecting primary users (PUs), the hybrid overlay/underlay spectrum access mechanism draws lots of attention recently. For such mechanism, this paper proposes a multi- steps cluster-based clock synchronization scheme, which is embedded in the CRN setup progress. Three steps are involved. Firstly, the neighbor/hierarchy is...
As one of the most popular topics in the Next Generation Network (NGN), Named Data Networking (NDN), a newly proposed network architecture centered on content data, targets on altering the existing communication protocol between Internet hosts. NDN uses data names rather than IP addresses for data transmission and re-designs the packet formats and the protocols between layers in order to substitute...
In this paper, a 13.56 MHz CMOS near-field inductive link power supply (ILPS) that can deliver 20 mA output current for implantable medical devices (IMDs) is proposed and fabricated. In the proposed ILPS, the pair of inductive link coils is constructed in the spiral shape with a ferrite core to save space and increase efficiency. Experimental results have shown that the near-field coils can transmit...
Numerous researches about Mobile IPv6 (MIPv6) have been proposed recently and the handover delay of the Mobile Nodes (MNs) among different networks is surely a worthy noticing issue. There are three major reasons for the MIPv6 handover delay: Movement Detection, Duplicate Address Detection (DAD), and Binding Update (BU), in, which DAD occupies most of the MIPv6 handover delay and influences real-time...
Nowadays, with the wide establishment of IEEE 802.11, more and more people use Wi-Fi to surf on the Internet. Due to the convenience and mobility of the mobile devices, a number of mobile users have been increasing greatly. For real-time video and VOIP have attracted much attention, the delay time of handoff is the most important issue for the service. In order to provide high-speed service with low...
The dynamical characteristics of a single neuron model with time delay under periodic stimuli are studied in this paper. The analysis of the linear stability and the existence of Hopf bifurcation are given. Some numerical stimulations justify that the results of the analytical method are valid by a comparison with those of direct numerical integration.
We present an "opportunistic" scheduling policy with the objective of improving delay performance for time-sensitive users in wireless networks. Since packet delay depends on both resource allocation and time-varying capacity of wireless channels, we introduce a search radius (SR) into the framework of packet fair queueing (PFQ) and employ maximum relative SNR (Max-rSNR) as scheduling rule...
