“…Any of the four stations can fail to connect with either of three others though they are logically interconnected through a same Wireless AP (WAP). There are almost three general cases with this problem as discussed in [15]: (a) -either all nodes cannot hear each other; (b)-or they are visible but in contention for resources each other; (c)-and else they are invisible stations and contention happens simultaneously.…”

“…Technically wireless network's invisible and exposed nodes problem is generally due to either radio wave interferences (e.g. Case with huge of users in hotspots and condominiums), or short range between contending nodes [6,13,15]. Therefore, network topology must be accounted at least in maintenance process; that is because of the position nodes location involvement into hidden nodes problem.…”

“…The increase in delivery delay originates from retransmissions and its execution time [3,4,6]. In overall, the network operation ends up with a poor services quality resulting from performance degradation due to the above stated facts [6,15]. However, in wireless network, hidden receiving stations problem is among the first severe causes of WN performance degradations [13] and thus low QoS [3,4].…”

“…Thus, such a change situation is a cause to their operation problems and solutions difference [13]. Hence, various research studies showed that RTS/CTS mechanism is not considered suitable for MANET environment but instead CSMA/CA based distributed MAC in each terminal [5,6,15].…”

“…Fig.1 node ‗C') to which it wanted also to transmit packets to, this node (‗A') will simply drop its own packets without genuine proof for probability of loss [14] in the case that those packets could have been sent. And, such false abstentions consequently will gradually reduce the network throughputs delivery [2][3][4][5][6]15], then the performance and finally the QoS on top of all.…”

Abstract-Wirelesslocal area network (WLAN) communications performance design and management have evolved a lot to be where they are today. They went through some technology's amendments and innovations. But, some performance tools remained almost unchanged and play a fundamental role in contemporary networking solutions despite the latest innovations higher influence on their indisputable and important function. That is the case with Request to send (RTS) and consent to receive (CTS) protocols. They are among the former technologies, which helped for transmission control with better performance in WLAN environment. They are so important, particularly since the advent of sensitive data networking (e.g. internet telephony, audio and video materials distribution) over the internet protocol (IP). Up to recent years following today's multimedia WLAN based networks deployment trends, RTS/CTS) contributed to provide networks with some expected good performance levels prior to the discovery of more sophisticated methods for this purpose (i.e. performance enhancements). And yet, one may question whether the new technologies have rendered RTS/CTS frameworks obsolete; or are they now used only for some specific network applications traffic management? This articles review attempts to comprehensibly study some of the research works, which have had interest in RTS/CTS mechanism as tools for WLAN applications performance support. Various researches have studied these tools from their early innovation as network node's built-in component, through different frameworks associated with WLAN legacy (IEEE 802.11) MAC protocols. This paper analyzed RTS/CTS initial implementation as mere network performance solution from packets' collision avoidance perspective; and then for transmission delay due to hidden nodes and their false deployment. The article closes up on a critical analysis on the possible long time contribution of these protocols into integrated schemes based WLAN QoS performance design.
