StudyonSecurityofNextGenerationNetwork.rar - Since current studies on NGN mainly focus on
passive defense, which has a certain limitation in such aspects as technique realization, the paper starts from a detailed analysis on security vulnerability of NGN, and
then discussed possible attacks by hijack, concluded NGN attacks, suggested the key active defense strategies in network-built security, boundary security, access security and information transmission security, and
presented the developing direction to be studied further,providing a good reference for the research on NGN.,2010-02-08 21:46:13,下载4次
WhatisBluetooth.rar - Bluetooth is a standard for short range,
low power, low cost wireless communication
that uses radio technology. Although originally envisioned as a cable-replacement technology by Ericsson (a major cell phone manufacturer) in 1994, embedded Bluetooth
capability is becoming widespread in
numerous types of devices. They include intelligent devices (PDAs, cell phones, PCs), data peripherals (mice, keyboards, joysticks, cameras, digital pens, printers, LAN access points), audio peripherals (headsets, speakers,
stereo receivers), and embedded applications
(automobile power locks, grocery store updates, industrial systems,MIDI musical instruments). Ericsson joined forces,2010-02-08 21:40:46,下载4次
NGNArchitecture.rar - This article summarizes the architectural
aspects of a next-generation network in terms of general principles, functional representation, and typical implementation. According to the general reference model, which assumes decoupling of services and transport, NGN can be represented by multiple functional groups. One of the key implementations for session-based services, utilizing an IP multimedia subsystem, is introduced with enhanced features to meet both fixed and mobile network requirements.,2010-02-08 21:36:51,下载4次
NextNewGenerationNetworksServicesandManagement.ra - New/Next Generation Networks aim to provide
mutual trusted IP Based Networks for a multi access
network and innovative services tailored to users
needs. NGN architecture has been the purpose of
several studies within organism of standardization
like ITU-T and ETSI.
We present here a literature about NGN
architecture (NGN) and Next/New Generation service (NGS) requirements: details about functionalities of NGN layers and IMS (IP Multimedia Subsystem) Architecture are in the scope of the paper.,2010-02-08 21:27:05,下载5次

RoutinginZigBee.rar - An IEEE 802.15.4-based Wireless Sensor Network
is considered, and the relationship between the IEEE 802.15.4 topology formation mechanism and possible routing strategies at the network layer is studied. Two alternative routing schemes proposed in the framework of the ZigBee Alliance are analyzed.The first is the well-known Ad-hoc On demand Distance Vector
(AODV) routing protocol, which was designed for highly dynamic application scenarios in wireless ad-hoc networks. The second is
a tree-based routing scheme based on a hierarchical structure established among nodes during the network formation phase. This latter approach, referred to as HERA (HiErarchical Routing Algorithm) in the paper, routes packets from sensors to sink based on the parent-child relationships ,2010-02-08 21:16:51,下载57次
