| Summary: | Internet of Things (IoT) had undergone an increasing popularity due to its significant features that is able to connect devices to the internet. As a result, Wi-FI enabled Wireless Sensor Node gain popularity as an implementation of IoT. To achieve satisfactory quality of service (QoS) for a Wi-FI enabled WSN system, an interference management is one of the most crucial operation. In this paper, a simple yet effective method of IEEE 802.11 interference management method at the physical (PHY) layer is introduced, where it effectively associates the node with the best available Access Point (AP) in the vicinity, ensuring a seamless connectivity to the internet. The selection of AP includes evaluating three criteria: link margin (LM) of APs, channel distance (CD) between adjacent APs, and the probability of detection (Pd) of APsThe results show that the algorithm is a promising solution by ensuring that the system is automatically connected to the best available AP and thus, reducing interference to the minimum. |
