Receiver Initiated Multiple Access For Ad-Hoc Networks

Tech ID: 10192 / UC Case 2000-360-0

BACKGROUND

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.

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.

APPLICATIONS

This new invention has applications in wireless networks.
