Packet reservation multiple access for local wireless communications

Abstract

Packet reservation multiple-access (PRMA) allows a variety of information sources to share the same wireless access channel. Some of the sources, such as speech terminals, are classified as periodic and others, such as signaling are classified as random. Packets from all sources contend for access to channel time slots. When a periodic information terminal succeeds in gaining access, it reserves subsequent time slots for uncontested transmission. Computer simulations reveal that PRMA combines high bandwidth efficiency with low control complexity and the flexibility to accept information from a diversity of sources. It is considered a promising technique for wireless access to future telecommunications networks.< >
