CAREER: Development of a Mobile Architecture (Mobi-Arch)

研究计划：1996年9月举行的第二次互联网状况圆桌会议指出，互联网的发展将遵循三条道路：多媒体、多播和移动性。该项目结合了三条演进路径中的两条：组播和移动性。笔记本电脑和掌上电脑现在可以负担得起的价格买到；研究表明，笔记本电脑目前占电脑销售的35%。随着对笔记本电脑的爆炸性兴趣，现在人们希望无论用户在哪里都能连续访问互联网。换句话说，用户想要一个互联网版本的蜂窝电话。组播功能(将消息传输到一组主机而不是一台主机)是Internet上的一项重要功能。目前，数以千计的用户通过其众多的多播应用(例如，视频会议系统)从MBONE或多播骨干网获得数据。此外，由于多播设施是下一个版本的互联网协议(IPv6)的一部分，更多的用户将开始定期使用多播应用程序。该项目涉及移动性和组播。互联网工程任务组将组播列为我们未来移动环境中的一项所需服务。然而，当前用于移动主机的因特网协议不处理多播，并且当前因特网多播协议不向移动主机发送消息。这个项目是开发协议，将允许移动主机在互联网上高效地发送和接收组播消息。欲了解更多信息，请参阅http://cs.ua.edu/faculty/camp/camp.html/mobi-arch.html教育计划：该项目的教育方面围绕“计算机领域的女性”问题展开。在过去的一年里，我们一直在探索计算机科学中的性别问题，因为在我们这个领域，女性比例的下降令人沮丧。在这个项目中，我们将在大学和社区中发起一个项目，试图减少我们所在领域看到的女性人数减少的趋势。欲了解更多信息，请访问http://cs.ua.edu/faculty/camp/camp.html/women.html。

Research Plan: The second roundtable on the state of the Internet in September 1996 stated that the evolution of the Internet will follow three paths: multimedia, multicast, and mobility. This project combines two of the three evolution paths: multicast and mobility. Laptop and palmtop computers are now available at affordable prices; studies indicate that laptop computers are currently 35% of computer sales. With the explosive interest in laptop computers, there is now the desire for continuous Internet access no matter where users are. In other words, users desire an Internet version of the cellular telephone. Multicasting capability (transmitting a message to a group of hosts instead of a single host) are an important facility on the Internet. Thousands of users currently obtain data from the MBONE or multicast backbone through its numerous multicasting applications (e.g., video-conferencing system). Furthermore, since a multicasting facility is part of the next version of the Internet Protocol (IPv6), even more users will begin using multicasting applications on a regular basis. This project concerns both mobility and multicasting. The Internet Engineering Task Force lists multicasting as a desired service in our future mobile environment. However, the current Internet protocol for mobile hosts does not handle multicasting and the current Internet multicasting protocol does not transmit messages to mobile hosts. This project is to develop protocols that will allow mobile hosts to transmit and receive multicast messages in the Internet efficiently.

Over the past year, we have been exploring gender issues in computer science, since the decreasing percentages of women in our field is discouraging. During this project, we will initiate programs a t the university and in the community to try to reduce the decreasing female trend that we are seeing in our field.
