| Abstract | Two of the most important wireless wide area networks are Mobile Intcrnu( Protocol (IP), developed by the -Mobile 1P Working Group of the Internet Engineering Task Force (IETF) and Cellular Digital Packet Data (CDPD), proposed by thc CDPD Forum. In spite of their common roots the two protocols have some important diffsrenccs which affect their performance during some critical phases of wireless communications. Two examples are the handhg of the initial registration of the mobile node with the mobile base station and with its home network, and the handling of handofls. In this thesis we concentrate our attention on the network layer perfbrtnrtncc by studying the number and size of the messages exchanged during the critical phases as well as the efficiency of the routing of packets from and towards the mobile nude, Thc draft proposal for route optimization in Mobiie IP is also considered and its imprt>vcd routing performance is compared to the base Mobile IP and CDPD protocols. The performance of the two protocols as well as three variations: intra-arca handoff for CDPD, multiple bindings for Mobile IP and the route optimization proposal for Mobiie IP, are measured using the Optimized Network Engineering Tools (OPNET) simulation package. The simulation results are verified using analytical queueing methods. The Transmission Control Protocol (TCP) is used as the transport layer for all protocols and various scenarios of operation of the mobile connection are applied, such as a file transfer with a constant stream of equally sized packets and a Poisson stream of packets. CDPD and the base Mobile If protocol simulations show very little differences in their performance in spite of CDPD's use of slightly shorter registration packets. In addition, the simulations show a significant improvement of throughput and end-to-end delay for the optimized Mobile IP while the mobile node is operating within a single cell. The improvement depends on the extra overhead introduced by the triangular routing of the base protocols. During handoffs, however, optimized Mobile IP is outperformed by both the base Mobile IP and CDPD due to the outdated location caching. |
