Proxy services for the mobile internet

The mobile Internet employs various wireless networks to enable mobile clients to access Internet services. As wireless links generally suffer from limited bandwidth and higher error rates when compared to wired links, the performance of Internet access is often less than ideal. A common approach to overcome this problem is to use a proxy to enhance the performance of the mobile Internet. This paper provides an overview of a number of proxy services being developed at the University of British Columbia under the "Multimedia content delivery over the mobile Internet" project. These services include header/data compression for wireless application protocol, vertical handover support between cellular and wireless local area networks, and multi-channel transport layer security.
