Assume a wireless network consists of an access point (denoted as X) and two wireless nodes (denoted as A and B respectively). Assume that wireless nodes A and B cannot hear each other's transmissions, but they can hear X (i.e. X can hear A and B). Suppose ● At time 0 µs, X is sending a packet to some other node and it completes sending this packet at time 100 µs. At time 20 µs, a packet becomes available for transmission at A. A needs 150 µs to send this packet. At time 60 µs, a packet becomes available for transmission at B. B needs 100 µs to send its packet. Let the value of the backoff timer for A be 40 µs and the value of the backoff timer for B be 60 μs. 1) Sketch the above described topology to include wireless nodes X, A, B, and their coverage. You may use tools such as Word, Paint, Visio, etc. to complete this topology.
Introduction
Wireless Network:
Wireless networks are communication networks that is not linked by any kind of transmission line. The use of wireless connection helps corporations to avert the costly process of installing cables in buildings or integrating different equipment locations. Wireless systems are built on radio waves, which are implemented just at the physiological level of the network structure.
Nodes:
A node is a network connection point that can serve as either a spinoff point or perhaps an endpoint. An address is permitted for such a node to interact on a network in order for the system to properly path the information to the proper device. An IP Address is required for such a device to be linked to the Internet. This IP address will serve as the network's standard way of referencing a device's unique Device Identifier, also identified as a MAC address. This enables the network to communicate with the appropriate node or device.
