Effective Web caching for GPRS networks

During recent years, providing Web access to mobile users has become a major focus of the wireless network operations. A number of Web caching schemes have been proposed to improve response time of wireless Web access. Nevertheless, none of these schemes fit well into the GPRS model, which is an IP-based packet-switching extension of GSM. In this paper, various factors that must be considered in designing a Web caching scheme for GPRS are discussed. By taking those factors into account, we employ a known Web caching scheme, CNP, and extend its support of Web access for wireline networks into wireless GPRS environments. We also present how to incorporate CNP to deal with the Web proxy placement problem for GPRS
