We have developed an algorithm based on hybrid nodes composed of an XBee S2C module configured in API mode with escape and connected to a microcontroller ATMEGA 328P to solve the orphan node problem of a ZigBee tree topology. The sensor nodes have both features End Device and Router that may alternate depending on the situation, and the node can adapt itself to keep the network integrality as much as possible. On the other hand, the coordinator node comprises an XBee S2C module and the embedded system Raspberry Pi 3, which hosts the algorithm and is set up as an access point, a database server, and a web server. Using the proposed algorithm, we were able to recover up to 42.8% of the network coverage, but it comes with an energy cost due to the switch from End Device to Router. Additionally, a mobile application integrated with notification service and Google Maps was developed to monitor every node’s behavior in the Wireless Sensor Network.

In order to optimize the traffic flow on a road intersection, an adaptive control algorithm and a data base were designed; both components were hosted on a Raspberry Pi B+ embedded system. The data base helps to debug the performance of the controller. The efficiency of the algorithm was assessed using a virtual instrument, which emulated a traffic light intersection in the city of Cucuta, i. e., the magnetorresistive sensors, the activation process of the traffic lights and the traffic flow. By processing and updating the times assigned to the traffic lights, the traffic flow was increased up to 5.5 % and the maximum time a vehicle has to wait before passing through the traffic light was decreased up to 28 seconds. Aditionally the length of line was diminished up to 18 %. Based on this case study, it can be inferred that is possible to integrate the adaptive control and the embedded systems as software and hardware tools to improve the operation of traffic control systems.
