Abstract:This thesis attempts to answer these questions by an- swering the research question "How can smartphones be used in environmental sensing, in the context of a city-wide project, and what are the challenges to overcome?". A prototype was designed and implemented to demonstrate the feasibility of using smartphones in environmental sensing with the focus on using opportunistic communications instead of cellular communications. The prototype consists of a webserver, Android smartphones and sensor nodes. The communication to the sensor nodes is achieved using Bluetooth Low Energy, the communication between smartphones is achieved using Cocoon. The prototype was tested in both a simulator and in a testbed. The simulator was used to simulate larger scale networks and scenarios which could not be tested in the testbed and the testbed was used to demonstrate the feasibility of usage. The prototype was able to communicate with the sensor node using Bluetooth Low Energy and to other smartphones using Cocoon although some device-specific problems were observed. The smartphones aggregated and shared the data which were later visualized to the users. The smartphones were able to upload their data to the external server in which the uploaded results are visualized via a website.
