Abstract
In the last few years, WiFi becomes popular in wireless technologies, and nowadays, WiFi is one of the most exciting and demanding technique for research work. Generally, WiFi technology formed a one-hop network with many nodes. Due to several areas of applications of WiFi in the internet of things, this work improved a one-hop WiFi network to a multi-hop network using wemos Dl R2 ESP8266 by changing its mechanism. To construct a multi-hop WiFi network has focused on each node's hardware. The node's hardware contained one access point (AP), one station (STA), one controller, various sensors, and a relay board. The motive of this work is the construction of an offline WiFi network by multi-hop nodes. So that relays controlling, and sensors monitoring of every node can be done, using a mobile application (APP), by connecting to any single node. Experimental purpose, the same two WiFi modules have used for AP and STA mode. Such that the framework of one-hop AP mode can change to a combined AP+STA mode.
