Development of a Simulated Portable Mesh Network via ESP8266-Based Devices with Utility Application

Abstract

Mesh network is very effective for node-to-node communications. In networks that require and demand devices for home monitoring and control, uncommon topology like Mesh is viewed to have a more effective advantage. However, when it comes to networks, Mesh Network is almost left untouched in most studies simply due to the existing network solutions such as WLAN or Bluetooth. The existence of low-powered WPAN devices fill the demand in integrating devices into mesh networks. However, constant configuration could be very complex and difficult for a mesh using existing WPAN devices since nodes constantly move in and out dynamically in the mesh network. This study focused on the development of a simulated mesh network through ESP8266 enabled devices to deliver a straightforward setup and portable connectivity. The study also developed a utility application that integrates an algorithm for node network operations, and a facility that keeps track of mesh network information including delays, node connections, and data transmission. Three(3) portable ESP8266 devices were used and configured in the study. The devices were integrated in a simulated mesh network and subjected to network processes including identity tagging, dynamic connection, routing, One-way Delay and Payload Size Tests. Results of One-Way Delay and Payload Size Tests indicate consistency of transmission and receiving of data of nodes connecting and disconnecting to the simulated network. This can be used as basis in extending further into more high-end nodes like handheld devices and even computers. Similarly, the utilization of dedicated algorithm for Mesh in this study proved that portability can be achieved to avoid loss of connection when nodes abruptly fail in the network.
