WTCP ("Wireless Transmission Control Protocol") is a proxy-based modification of TCP that preserves the end-to-end semantics of TCP. [1] As its name suggests, it is used in wireless networks to improve the performance of TCP.
Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...
Wireless energy transfer may be combined with wireless information transmission in what is known as Wireless Powered Communication. [35] In 2015, researchers at the University of Washington demonstrated far-field energy transfer using Wi-Fi signals to power cameras. [36]
In version 4, the monolithic Transmission Control Program was divided into a modular architecture consisting of the Transmission Control Protocol and the Internet Protocol. [ 5 ] [ 6 ] This resulted in a networking model that became known informally as TCP/IP , although formally it was variously referred to as the DoD internet architecture ...
In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity. [1] Examples of shared physical media are wireless networks, bus networks, ring networks and point-to-point links operating in half ...
Node D is unaware of the ongoing data transfer between node A and node B. Node D has data to send to node C, which is in the transmission range of node B. D initiates the process by sending an RTS frame to node C. Node C has already deferred its transmission until the completion of the current data transfer between node A and node B (to avoid co-channel interference at node B).
Meanwhile, a node that hears RTS should remain silent to avoid conflict with CTS; a node that hears CTS should keep silent until the data transmission is complete. WLAN data transmission collisions may still occur, and the MACA for Wireless is introduced to extend the function of MACA. It requires nodes sending acknowledgements after each ...
Using frequency hopping and sweep modes, Zinn's method is primarily applied in low data rate wireless applications such as utility metering, machine and equipment monitoring and metering, and remote control. In 2006 Zinn received U.S. patent 6,996,399 for his "Wireless device and method using frequency hopping and sweep modes."
