This article presents ZigZag. design that combats hidden terminals. The core contribution of ZigZag is: The use of directional antennas in ad hoc networks can introduce the well-known deafness problem, aggravate the hidden terminal problem and the exposed terminal problem, and increase the problems in mobile. However, the topologies of ad hoc networks differ significantly from those of access point-based wireless networks, hence the effect of hidden ad-exposed terminals in ad hoc networks. Exploiting concurrent transmission is a promising way to improve throughput in wireless networks. Existing MAC media access control protocols, such as carrier sense multiple access, always try to minimize the number of simultaneous transmissions to avoid collisions, although sender-side collisions are harmless to overall performance; Networks, the medium access control or media. access control MAC layer is the bottom sublayer of. the data link layer of the seven-layer OSI. fashion model. The MAC sublayer provides. In a wireless ad hoc network MANET, nodes can form a centerless, self-organizing, multi-hop dynamic network without any centralized control function, while taking hidden and exposed terminals seriously. The interference-aware multi-access IAMA scheme for medium access control MAC in ad hoc networks and multihop wireless LANs is proposed, which is the first and only distributed MAC scheme reported in the literature so far that can solve the additive interference problem using the same channel. shared by both data packets. This paper proposes a new Directional MAC protocol to address the Directional Hidden Terminal problem and the Directional Exposed Terminal problem and proposes a new Directional MAC protocol for mobile ad hoc network. The mobile ad hoc network is deployed in an environment where a traditional wired network cannot exist. Hidden station problem HSP: When two stations that are hidden from each other, i.e. not within range of each other, send signals to a third station at the same station, assuming the third station is free. It causes a collision at the third station and is known as the Hidden Station Problem. It reduces the capacity of the network due to the possibility of collisions. Resume. Ad hoc networks suffer from the problem of hidden nodes, terminals, which leads to serious deterioration of network throughput. This study provides a comprehensive overview of MAC medium access control protocols that directly or indirectly address this problem. The presented protocols are grouped into several. An analytical model is proposed that deals with the channel utilization metric in hoc networks, taking into account the hidden terminal problem and the results show that the model is reasonably accurate. The paper proposes an analytical model that deals with the channel usage metrics in hoc networks. The,
