Intelligent Concept of Optimal WiFi Mesh Router Placement for Enhanced QoS

WiFi Mesh Router (WMR) is a common requirement nowadays in home WiFi networking and Internet of Things (IoT). Placement of these WMR is very important and will directly impact the overall WiFi Mesh network performance. Current state of art recommends, the placement of WMR by considering only connectivity (i.e. multi-hop path between WMRs), and during the initial setup of WMRs. The paper proposes a novel Intelligent WMR Placement (IWMRP) algorithm to recommend the optimal placement of WMR. This improves Quality of Service (QoS) of client devices in the WiFi environment which changes based on various factors. In this concept, first, we collect statistics (such as bandwidth requirement, traffic pattern, traffic type, etc.) from client devices through WMR and vice versa over a period. Later, the captured statistics will be learnt in the form of weights in different grid zones of the deployment area. Using these weighted grid zones, we find out the optimal placement of WMRs using proposed IWMRP algorithm. The simulation results show that there is a significant improvement in Received Signal Strength Indication (RSSI) around 9%, an average distance reduced around 43% and coverage percentage improved around 35%, when comparing with existing WMR placement.
