TL;DR: A new RTS/CTS On/Off control method for mitigating transmission overhead of IEEE802.11 induced by RTS-CTS handshake is proposed and results from computer simulations confirm that the proposed method improve throughput performance in around the saturated traffic environment.
Abstract: IEEE802.11, the widely used wireless LAN standard, employs RTS/CTS handshake to avoid a packet collision with the transmissions from hidden terminals. Although RTS/CTS handshake effectively reduces packet collisions with hidden terminals, it also increases transmission overhead of IEEE802.11. In this paper, we discuss transmission overhead of IEEE802.11 induced by RTS/CTS handshake, and propose a new RTS/CTS On/Off control method for mitigating transmission overhead of IEEE802.11. Results from computer simulations confirm that our proposed method improve throughput performance in around the saturated traffic environment.

TL;DR: In this paper, an asynchronous handshake signal (111,151) is encoded in order to facilitate the transfer of the handshake signal from a first network segment (10) to a second network segment(30).
Abstract: An asynchronous handshake signal (111,151) is encoded in order to facilitate the transfer of the asynchronous handshake signal (111,151) from a first network segment (10) to a second network segment (30). On the first network segment (10), control signals and data signals are encoded as control symbols (122,125,128,130,132,135,138,140) and data symbols (123,127,129,133,134,137,139), respectively. The control symbols (122,125,128,130,132,135,138,140) and the data symbols (123,127,129,133,134,137,139) are transferred from the first network segment (10) to the second network segment (30) across an interconnection medium (41,42). In order to send a handshake signal (111,151) from the first network segment (10) to the second network segment (30), the handshake signal (111,151) on the first network segment (10) is sampled. When the handshake signal (111,151) on the first network segment (10) is at a first signal level, a control symbol (122,125,128) of encoded control signals is sent across the interconnection medium (41,42). When the handshake signal (111,151) on the first network segment (10) is at a second signal level, a data symbol (123,127,129) of encoded data signals is sent across the interconnection medium (41,42).
TL;DR: A general-purpose interface circuit which will enable two-way communication of data between an instrument and the IEEE 488 bus has been described and an example application for converting a Keithley 616–6162 electrometer to IEEE 4 88 compatibility has been discussed.
Abstract: A general-purpose interface circuit which will enable two-way communication of data between an instrument and the IEEE 488 bus has been described. An example application for converting a Keithley 616–6162 electrometer to IEEE 488 compatibility has been discussed. The interface provides Talker, Listener, Source Handshake, Acceptor Handshake, Device Trigger and Device Clear functions as defined in IEEE Std. 488 (1975).

TL;DR: In order to settle the conceal terminal, frequency shift, losing package, mistaking code problems of air-to-ground data link, which were arosed by high speed moving of node and more complicated network enviroment, two important MAC communication mechanism-the MSDU frames subsection and RTS/CTS handshake mechanism were introduced.

Then some simulation experiment were made from little operation and much operation aspects, and some simulation analyse was given. Finally, some useful conclusion is got.

TL;DR: The main problems facing Ad Hoc channel access are expounded, computer simulation experiment of CSMA protocol with monitoring function, and computer simulation Experiment of CSma protocol with three simulation mechanism are conducted to hope that the computer simulation can be helpful through the simulation test for such researchers.
Abstract: Due to its dynamic and changing network topology structure, AdHoc network can carry out wireless transmission of data, voice, video and other services in harsh conditions. Therefore, whether in the military field, or in the field of civil or commercial field, Ad Hoc network has great development prospects.The access protocol of Ad Hoc network wireless channel has always been the key and difficult point of scholars at home and abroad. System throughput, channel utilization rate and system delay all depend on the protocol used.Based on this, this paper mainly expounds the main problems facing Ad Hoc channel access, computer simulation experiment of CSMA protocol with monitoring function, computer simulation experiment of CSMA protocol with three simulation mechanism, hope that the computer simulation can be helpful through the simulation test for such researchers.
