The advent of mobile IP communication has opened up several new areas of mission critical communication applications. But the bandwidth and reliability constraints coupled with handover latency are posing some hurdles which need to be overcome before real world mobile IP applications, with low tolerance for data loss, can be deployed. In this paper, we analyze the unreliability of existing information collection methods in the real-world MobileIP environment. We focus on this problem and propose a novel network management model that anticipates the wireless mobile entities and uses SNMP. The key idea of this model is the introduction of a store-and-forward type Managed Object (MO). During the period of unreachability between the Manager and the agent, the data is cached at the agent until the connectivity recovers. In our experiment we used a prototype implementation in real-world wireless communication field, and showed the effectiveness of our proposed method.
