     Consider the situation depicted in the figure, where each of the four nodes is able to send and receive signals that reach just the nodes to its immediate left and right. For example, B can exchange frames with A and C but it cannot reach D, while C can reach B and D but not A. (A and D’s reach is not shown in the figure.) Suppose both A and C want to communicate with B and so they each send it a frame. A and C are unaware of each other since their signals do not carry that far. These two frames collide with each other at B, but unlike an Ethernet, neither A nor C is aware of this collision. A and C are said to be hidden nodes with respect to each other. According to Wikipedia, the hidden node problem can be defined as “In wireless networking, the hidden node problem or hidden terminal problem occurs when a node is visible to a wireless access point (AP), but...

   • WLAN Full Form

     WLAN stands for Wireless Local Area Network. WLAN is a local area network that uses radio communication to provide mobility to the network users while maintaining the connectivity to the wired network. A WLAN basically, extends a wired local area network. WLAN’s are built by attaching a device called the access point(AP) to the edge of the wired network. Clients communicate with the AP using a wireless network adapter which is similar in function to an ethernet adapter. It is also called a LAWN is a Local area wireless network. 

     The performance of WLAN is high compared to other wireless networks. The coverage of WLAN is within a campus or building or that tech park. It is used in the mobile propagation of wired networks. The standards of WLAN are HiperLAN, Wi-Fi, and IEEE 802.11. It offers service to the desktop laptop, mobile application, and all the devices that work on the Internet. WLAN is an affordable method and can be set up in 24 hours. WLAN gives users the mobility to move around within a local coverage area and still be connected to the network. Most...

   What is multiple access with collision avoidance for Wireless (MACAW)?

   • Multiple Access with Collision Avoidance for Wireless ( MACAW) is a slotted medium access control (MAC) protocol widely used in ad hoc networks. Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.

   What is carrier-sense multiple access with collision avoidance (CSMA/CA)?

   • Carrier-sense multiple access with collision avoidance ( CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle".

   Why do wireless networks need to avoid collisions?

   • Wireless networks must avoid collisions to ensure packets reach their destination. What Are CSMA/CA, RTS/CTS, and MBCA? If a collision is detected in wired IEEE 802.3-2022 technologies, packets can be present, unlike in wireless technologies, where there is no way to detect a collision over the air.

   The main difference is the collision avoidance: on a wire, the transceiver has the ability to listen while transmitting and so to detect collisions (with a wire all transmissions have approximately the same strength).

   • In a wired CSMA/CD Ethernet environment, it is possible to detect a collision because there are separate TX and RX pairs (using the example of 10Ba...
   • Avoidance is used for the very simple fact that every radio ("client") is not necessarily in range of each other. Thus, without the AP coordinating...
