Traffic-Based Performance Comparison of Mobile Support Strategies

This paper presents performance comparison among ve strategies for mobile support. The major facilities that are required for a network protocol to support mobile hosts are location management and packet forwarding. Based on this observation, we consider ve basic strategies which use distinct methods to achieve these facilities and compare their performance. These ve strategies are Broadcast Noti cation (BN), Broadcast Forwarding (BF), Broadcast Query (BQ), Default Forwarding (DF), and Default Query (DQ). As a result of analytical evaluation and comparison, it is shown that under di erent network conditions, such as number of routers, network topology, migration/communication ratio, data/control packet size ratio, di erent strategies produce minimum network tra c. In short, DF and DQ show the best performance in network size scaling, while BF and BQ are e cient for frequent migration. On the other hand, BN is suitable for a small network which has hosts with infrequent migration.
