Abstract
LEO is Low Earth Orbit satellite.It circulates on a lower orbit in a shorter period . Additionally LEO systems try to ensure a high elevation for every spot of the earth to provide a highquality communication page link . The networks will play an important role in the evolving information infrastructure . It provides communication with shorter endto- end delays and e_ciency frequency usages . Some problems need to be solved before LEO satellite system can be successfully deployed . One of these problems is handover management . Even ....etc

Advance in network technology leads to the design of new protocols and services. In order to assure successful communication among those new products, testing and validation activities for conformance and interoperability play an important role in the development and deployment of them. In this lecture, we introduce the PLATONIS platform, a platform for validation and experimentation of new protocols and services. The platform is focused on WAP protocols and services, but it is expected to be general enough to be used for other protocols and se ....etc
