“…The authors proposed a protocol named RI-DMAC (Receiver Initiated Directional MAC) in [6]. In this protocol, when the sending node completes the data transmission, it sends a RTR (Ready to Receive) frame to the receiving node, so that the receiving node can receive the data frame of the potential sending node, thus greatly reducing the time of deafness.…”

Abstract. Using directional antennas is an effective method to improve the bandwidth utilization in wireless ad hoc networks. However, what remain unaddressed, are the new challenges with MAC protocol design induced by the directional transmissions, such as deafness problems, new hidden terminal problems etc. To solve these problems, in this paper, we propose a directional concurrent MAC protocol based on local synchronization for wireless ad hoc networks with directional antennas. In this protocol, we introduce a channel reservation gap based on local synchronization method for the adjacent nodes, i.e., a channel reservation gap is inserted between the transmission of the RTS/CTS and data packets to offer the neighboring nodes the chance to schedule possible overlapping directional transmissions. Further, the length of the channel reservation gap can dynamically adjust according to the channel situation. Simulation results show that, compared with the typical Nasipuri DMAC protocol, the protocol proposed in this paper can achieve significant throughput improvement.

“…In spite of transmitting multiple DRTS/DCTS frames , the schemes in [7,15] will be exploring a concept that specify potential senders. The author is proposing an advance notice directional MAC (AN-DMAC) in which it is using a additional (ARTS) frame to specify al the potential senders To wait till another node completes its transmission for avoiding the deafness in [7].…”

“…Thus ,the inventor of DRTS will be trying more DRTS frames ,which will be increase the contention window, within which other nodes messages will be blocked. On the basis of our classification, the current solutions to the deafness problem can be divided as (1) methods using multiple control frames [12];(2) methods that specify potential senders [7,15];(3) tone based Approaches [3,5].The concept of multiple control frames are trying to solve the problem of deafness by revealing the transmission information to all the nodes who are neighboring. For avoiding deafness in order to delay their communication and the forthcoming communication the nodes which receives the control frame understand.…”

A favorable technique is using directional antennas for highspeed wireless personal area networks and local.A new MAC protocol for wireless ad hoc networks which is referred to as New deafness-aware MAC(NDA-MAC) is proposed in this paper. There are many directional MAC protocols which have been proposed, but have not broadly solved the problem of deafness. We are proposing NDA-MAC protocol which can differentiate the deafness problem from collisions by using control channels and logical data.so we are providing a discrete-time Markov chain model for analyzing the deafness impact for both DA-MAC and the current technique. By wide simulations we are showing our NDA-MAC protocol can expressively perform the other current techniques with respect to the duration of deafness , throughput , transmission fairness and energy consumption. Mainly Ad-hoc networks are suffering from hidden nodes(terminals) problem ,leading to the problem of the nodes which are hidden (terminals), which indicates to Spartan degradation in network throughput. A survey of this which will give a basic idea of MAC protocols which will directly or indirectly indicate this problem .The mentioned protocols are set in various for giving the reader a detail understanding for the growth made in types and are discussed in detail. To provide the reader a bottomless understanding for the progress done in enhancing the hidden node problem as well as a detailed comparison of various protocols are shown.

“…With regard to the telecommunications analogy, though target-initiated signalling is not a familiar concept, ' receiver initiated directional MAC ' , consisting of a series of sender-and receiver-initiated operations, has been proposed as a mechanism of overcoming ' deafness ' (when a transmitter repeatedly attempts to communicate with its intended receiver, but fails because the receiver has its beam directed away from the transmitter), one of the major problems with directional MAC protocols (Takata, 2009). Thus it appears that, for once, biologists have outdone their telecommunications cousins in the elucidation of novel signalling mechanisms.…”

The traditional classifi cation of signalling in biological systems is insuffi cient and outdated and novel efforts must take into account advances in systems theory, information theory and linguistics. We present some of the classifi cation systems currently used both within and outside of the biological fi eld and discuss some specifi c aspects of the nature of signalling in tissue development. The analytical methods used in understanding non-biological networks provide a valuable vocabulary, which requires integration and a system of classifi cation to further facilitate development.
