An Innovation Development of Various Collision Avoidance Mechanisms and Its Related Parameters in IEEE 802.15.1

Abstract

The IEEE 802.15.1 standard defines the wireless communication protocol for wireless personal area networks (WPANs). It is a crucial protocol for ensuring reliable and secure communication in WPANs. Effective communication depends on collision avoidance algorithms and parameters like any other communication protocol. Collision avoidance algorithms are used to detect and stop numerous devices from transmitting simultaneously on the same frequency channel. This is significant because it enables efficient, interference-free data transmission and reception. Collision avoidance in IEEE 802.15.1 is accomplished by using a contention window. Every node in the network is permitted access to the channel to transmit data during the congestion window. The signal will collide if two nodes try to share simultaneously, and the data will be lost. The minimum contention window (CWmin) and the maximum contention window (CWmax) are the two parameters that make up the contention window in IEEE 802.15.1. While the CWmax specifies the most extended time period that each node can wait before attempting to access the channel, the CWmin specifies the least amount of time each node must wait. The likelihood of a collision decreases with the length of the contention window.
