Message oriented middleware (MOM) is a specific class of middleware that operates on the principles of message passing or message queuing. Existing MOM syste doesn't support the function for mobile computing environment. In the near future, requirements of mobile computing will increase and more dynamic service for mobile computing will be required. And i nteracting with wireless networks is becoming almost commonplace. In this paper, we propose a MOBILE MOM system supporting mobile computing environment. It bases on existing MOM system. In MOBILE MOM system, MOBILE MOM applications executed on mobile hosts (MH) dynamically and asynchronously are connect with MOBILE MOM me ssage queue managers executed on fixed hosts (FH) through MOBILE MOM message agents executed on base stations (BS). MOBILE MOM can provide a level of fault-tolerance using persistent queues that allow messages to be reco vered when the system fails and very reliable, scalable and performance-oriented distribute...
