%X In a distributed computing environment, comprising mobile computers and wireless networks, users change their locations frequently while still expecting ¡°acceptable¡± levels of performance. This complexity will produce poor performance with no exact answer why? In such an environment, a new method of designing applications will be required. It is claimed that understanding network performance is an art rather than a science because in practice there is little underlying useful theory; so, experience with real world examples are used instead to develop rules of thumb [14]. This paper is fundamentally designed to describe types of mobile applications and the major performance factors needed to be considered when designing such kind of applications. Methods of connectivity: always connected, occasionally connected, and occasionally disconnected will be addressed as well. We are proposing a Mobile Information System (MIS) model. This model will address the needs for monitoring wireless environment where the mobile applications running in this area and how it is monitoring the performance factors. Also provided in the model are the features of the MIS, the pros and cons of the model, and a simulation to show the effectiveness of the model.
