WiFi multi access point smart home IoT architecture

Abstract

The paper presents the concept of the wireless sensor network dedicated to smart home applications. The innovative characteristic of this network is related to its use for information transfer and routing of selected sensors that simultaneously serve as Access Points and network clients. As a result, we obtain an alternative for the popular solutions based on AdHoc idea. Network traffic creates a cascading path for messages with optional selection of routes dependent on the strength of the received signal. Messages are transmitted between the AP using store and forward methods. Optionally, in order to save the consumed energy, customers transmitters can be switched solely during the transmission time. Sample implementations have been made on the basis of low-cost microprocessor controllers and communication modules commonly used in IoT. To verify correct implementation, some tests have been conducted, examining the quality and latency.
