Receiver Initiated Multiple Access For Ad-Hoc Networks
University of California System: University of California, Santa Cruz
posted on 09/19/2011
Current medium-access control (MAC) protocols for wireless networks are based on collision-avoidance handshakes between sender and receiver. Most of these systems are based upon a sender-initiated handshake, in which the sender uses a short control packet to ask the receiver for permission to transmit and then only transmits if the receiver sends a clear-to-send notification. However, under high-traffic conditions, an influx of control packets can adversely affect the network.
Suggested Uses
This new invention has applications in wireless networks.

Detailed Description
Scientists at the University of California have developed a novel single-channel, contention-based medium access protocol that reverses the traditional RTS-CTS collision avoidance handshake. This receiver-initiated approach results in more efficient collision avoidance protocols.
