Mobile computing is becoming increasingly important due to the rise in the number of portable computers and the desire to have continuous network connectivity to the Internet irrespective of the physical location of the node. Mobile IP, the more popular global mobility solution, was designed to support mobility of a single host. Even though the same protocol can be applied in the case of network mobility, providing connectivity to mobile networks introduces many issues related to the scalability, security and QoS. Instead, a mobile network can be cited as a remote site, trying to establish secured communication with the home network. This view of mobile network solves many issues related to QoS, security and scalability. The objective of this paper is to explore the possibility of using different VPN techniques to provide connectivity for mobile networks and measure the corresponding end-to-end performance of real time traffic and best effort traffic patterns.

We consider the fair flow problem in a multiple source multiple sink network, as applied to telecommunication networks. We present an iterative algorithm for computing fair routing in networks where the available resources are shared among competing flows according to a max-min fair sharing criterion. Our main objective is computing optimal routing paths, with regard to max-min fairness, in stable and known traffic conditions. It is a linear programming based approach which permits a lexicographical maximization of the vector of fair-share attributed to the connections competing for network resources. An optimality proof and some computational results are also presented.

A novel method focused on the symbolic computation of noise figures (NF) for MOS transistor (MOST) analog circuits, is presented. In order to improve the computation time, a pure-nodal-analysis (PNA) method is applied by modeling all the circuit elements using the nullor. To demonstrate the suitability of the proposed method, two illustrative examples are given, where the NF computed using the proposed method, is compared with the simulation results using HSPICE.
In this work, we realized a three-dimensional (3D) reservoir computing (RC) by utilizing the I-V nonlinearity and short-term memory of the dynamic memristor in 4-layer vertical array. The cycle-to-cycle variation of t...

Establishing grids is an important undertaking in developing scalable distributed infrastructures. In this paper we have proposed a model for agent-based grid computing from the implement point of view. Based on the model agent-based grid computing system AGEGC has constructed by MAGE which is a multi-agent environment platform. AGEGC has applied to develop several application systems presented in the paper. We believe that AGEGC will be useful platform for research on semantic grid.

The present study deals with parallel asynchronous iterations applied to the numerical solution of the obstacle problem defined in a three-dimensional domain. For the considered problem, the convergence analysis of the algorithm is made. Finally, the implementation of the algorithms are presented and computational experiments on IBM-SP3 are analysed.
