SMS——智能网的业务管理系统

本文叙述了智能网的业务管理系统所实现的３种功能：业务管理功能，网络管理功能和业务管理访问功能，还介绍了业务管理和网络管理之间的关系，ＳＭＳ的集中式和分布式两种体系结构及业务管理功能的设计方法和进一步研究方向。     

GSM预付费业务的研究与实现

本文首先介绍了ＧＳＭ预付费业务在欧洲推出和应用的情况，该业务的功能需求、类型和特点，最后较详细地讲述了通过设立预付费业务处理中心和智能网两种业务实现方案。文章认为，第一种方案对现有ＧＳ网络影响较小，易于实现，但不能对用户帐目完全实行监控，功能单一，采用非标准协议，对其应用和发展产生限制。     

一维车载Ad Hoc网络连接度分析

In this paper we analyze connectivity of one-dimensional Vehicular Ad Hoc Networks where vehicle gap distribution can be approximated by an exponential distribution. The probabilities of Vehicular Ad Hoc Network connectivity for difference cases are derived. Furthermore we proof that the nodes in a sub-interval [z1,z1 +Δz] of interval [0, z], z>0 where all the nodes are independently uniform distributed is a Poisson process and the relationship of Vehicle Ad hoc Networks and one-dimensional Ad Hoc networks ...

Web service composition algorithm based on TOPSIS

Independent quality of service(QoS)registration center is difficult to monitor QoS with lots of requests in Internet environment with a large number of services and lots of service requests.It is able to reduce the load and decrease the failure rate by using multiple QoS registration centers to monitor QoS of some services with lots of requests.In addition,the heterogeneous QoS data close to user’s habitual expression and adapts to the environment with complexity and uncertainty.This paper introduces a novel Web service composition algorithm based on technique for order preference by similarity to an ideal solution(TOPSIS)(WSCA_TOPSIS)to solve the above difficulties for the first time.WSCA_TOPSIS can support multiple decision-makers and heterogeneous QoS data.It includes three main steps:normalizing decision matrix,evaluating alternatives synthetically and evaluating group alternatives synthetically.Other contributions of the paper include a novel algorithm of aggregating QoS and a set of experiments that demonstrate the benefits and effectiveness of our approach.Experimental results show that the proposed algorithm can better support Web service composition with heterogeneous QoS data and multiple decision-makers.
