The Utility of Perceptive Communication Between Distant Wireless Nodes

Category: Software and Web Development, Networking and Communications

Overview CSMA-based MAC protocols require wireless nodes to share the transmission medium with other nodes that are within Carrier-Sensing (CS) range. Hence, operations that depend on and can potentially affect the state of the shared medium, such as admission control, require coordination and information sharing among these nodes. The CS range of wireless nodes is traditionally much larger than the reception range. Nodes that are outside reception range but within CS range can sense packet transmissions; however, they are unable to decode the packet contents. Direct messaging between these nodes is therefore not feasible for information sharing. This paper describes two perceptive approaches for communication with nodes within CS range.
