Performance optimisation of multiple access protocols for multiservice VSAT satellite networks

We develop a multiaccess scheme that, when applied to a VSAT satellite network, could efficiently accommodate traffic consisting of short, interactive data messages, longer file transfers and voice calls. This will enable a large number of users to share the satellite channel. The difficulties associated with the introduction of speech are discussed and ways to deal with these are suggested, so that VSAT systems could provide a wide range of multimedia services to geographically dispersed users
