In this paper, a smart parking system formed by the integration of smart mobile device applications and Internet of Things (IoT) technology is proposed. The system is able to guide users through the process of searching for a car park until they successfully park the vehicle in a parking lot. The features of the system can be divided into four parts: recommendation and reservation, outdoor navigation to the car park, parking lot detection, and car park indoor navigation. An algorithm is designed to compute the recommendation priority of car parks based on adjustable, given conditions. Outdoor navigation provides a dynamic guide to the user during the trip to the car park. The iBeacon is implemented in indoor navigation to locate the position of users. The RSSI value of the iBeacon is filtered through an algorithm to provide an accurate result. The performance of the iBeacon in a different set-up condition is also evaluated. A field test is performed to acquire data and investigate the operational feasibility of the proposed system.

Trashcans are the basic unit in the garbage-collecting procedure. This paper proposes an intelligent trashcan with flexible features, which is associated with a smart device application. The trashcan is able to detect RFID tags to decide whether to open its lid or not. The trashcan is also capable of moving around when it receives instructions from the remote application, and it has the ability to move according to a planned path. Different settings of the smart trashcan can be configured via the remote application. The proposed system has been implemented, and it is shown that the proposal is applicable.
