The Synchronous Collision Resolution medium access control protocol uses contention resolution signaling to arbitrate access to a shared wireless medium. This signaling also provides a mechanism that enables the protocol to provide quality of service and to manage physical layer characteristics. Authors explain how it: ensures that nodes sending higher priority packets get precedence in gaining access enables a node to reserve the use of the channel, conserves energy, and enables the coordinated use of multiple channels simultaneously in a flat network architecture. They describe and provide simulation results of how the use of multiple spread spectrum channels can dramatically increase the already extraordinary spatial capacity of the protocol.
