An AAA Application Protocol Design and Service for Secure Wireless Internet Gateway Roamingility in wireless IP access. This paper proposes a secured wireless Internet roaming service using wireless Internet Gateways (AAA Clients) and an AAA server. To support internetworking with wireless Internet gateways (i.e.,WAP G/W), we also designed a diameter application protocol and scenarios. Tr

Fast Move Detection over Mobile IP, the latency involved in these handoffs can be longer than the threshold value, required to support the delay-sensitive or real-time services. To reduce the latency for Mobile IPv4 handoffs, this paper presents a move detection mechanism within IP-layer. Proposed method is based on strict source ro

A New Location Caching Scheme Employing Forwarding Pointers in PCS Networksheme, the use of cache information can effectively reduce the signaling traffic for locating frequently called mobile users. However, when the cache information is obsolete, it results in much more signaling traffic than that of the IS-41. In order to solve this problem, we propose a new location ca

Evaluation of a Location Management System for Wireless Communicating Mobile Computersuch as cellular phones, wireless LAN, . In such an environment we aim to construct a system software on which mobile hosts can share the location-dependent information with other hosts. It is, however, difficult for users who request location-dependent information to identify mobile hosts providing

The Enhancement of End-to-End TCP on Wireless CDMA Network to Support Interactive Data Serviceta services require a dial-up to a data service. The benefit of using a circuit-switched data service is the ability to utilize existing wireless equipment i.e. a cell phone as a modem to connect to a data network, thereby reducing overall hardware costs. Once connected with packet data services, a

A Comparative Performance Evaluation of the Transport Layer Protocols for Wireless Transaction Proce compared to the other two protocols and introduces a fixed time interval for retransmission instead of the exponential backoff algorithm. The experiment also shows that the WTP performance is optimized when the retransmission counter is set to 5 or 6 in case of high burst error rate.

A New Location Caching Scheme Employing Forwarding Pointers in PCS Networks database access load on the HLR to the VLR’s. The analytical results indicate that the PB-Cache scheme significantly outperforms the other schemes when a user’s call-to-mobility ratio is high or the signaling traffic to the HLR is heavy.
