The result shows the reduction in ADC after applying the GWO algorithm than the initial placement and TLBO algorithm for all the cases considered for simulation. The proposed work is compared with well-known algorithm, namely teaching learning-based optimization (TLBO) algorithm. To check the effectiveness of the proposed work, simulation is done for varying numbers of wireless routers. ADC is the average of the distance of ONU and its associated wireless routers. GWO provides the optimum position of every ONU, where the average distance cost (ADC) is minimum. To the best of our knowledge, this algorithm has not been used for the ONU placement problem in the FiWi network. For this, a nature-inspired grey wolf optimization (GWO) algorithm is applied in the FiWi network. The present research work considers the ONU placement issue and proposes a novel algorithm for finding an optimum position of ONUs. ONU placement is the most important issue in FiWi as it affects the network cost and network performance. FiWi integrates the technical merits of the optical access network and wireless access network. We check that it has the SSID defined in the code.Fiber-Wireless is the promising next generation broadband access network. Once the access point is configured and the code is uploaded to the card, we can see in the available networks a new network appearing. If you do not call the softApConfig function to set the IP addresses, the network will use default addresses. If you want to change the SSID, make sure the password is longer than 8 characters or there is no password. Note: If the assigned password is shorter than 8 characters, the SSID will be ignored. max_connection number of simultaneous connections allowed from 0 to 8.hidden hides the SSID if true (Optional).Other parameters, such as the password or the number of connection limits can be defined. To configure a Wifi access point you just have to give it a name WiFi.softAP(ssid) To configure the ESP8266 NodeMCU as an access point, we will use the SoftAp class included in the ESP8266WiFi.h library. This configuration is called the AP (Access Point) mode The ESP8266 NodeMCU has a Wi-Fi chip that can generate its own network in case a Wi-Fi network is not available. This method is useful when you do not have access to a wifi network or if you want to work on a network specific to the microcontroller. The esp8266 microcontroller can be configured as an access point (AP) and generate its own wifi network with ssid and password.
