Many-to-Many Communication: A New Approach for Collaboration in MANETs

The authors introduce a collaboration-driven approach to the sharing of the available bandwidth in wireless ad hoc networks, which they call many-to-many cooperation, that allows concurrent many-to-many communication. This scheme is based on the integration of multi-user detection and position-location information with frequency and code division in Mobile Ad hoc NETworks (MANETs). Transmissions are divided in frequency and codes according to nodal locations, and Successive Interference Cancellation (SIC) is used at receivers to allow them to decode and use all transmissions from strong interfering sources.
