In this paper, the performances of the five query processing strategies are evaluated for multiple mobile hosts in a mobile computing environment. The five strategies are: (1) SBN, Single Broadcast Notification, (2) WBN, Double Broadcast Notification, (3) BQF, Broadcast Query Forwarding, (4) SDN, Single Default Notification, and (5) WDN, Double Default Notification. The optimum choices for particular network parameters; e.g., kinds of query, network topology, frequency of moving of mobile hosts, rate of generation of query, number of servers, and number of mobile hosts in query; are identified. The effects of a change in the number of mobile hosts on the optimum query processing strategy are examined. © 1998 Scripta Technica. Electron Comm Jpn Pt 1, 81(2): 1–9, 1998
