Smart city vehicular mobile sensor network

Abstract

Smart City concept comprises numerous technologies and heavily depends on sensors to be aware of its environment in order to adapt and to evolve. Wireless sensors networks thrive on the latest development of sensor technologies where sensors dynamically connect and rely on wireless networks which might not be available all the time or their geographical coverage can change depending on various circumstances. Special challenge are mobile wireless sensors where data transmission can be significantly obstructed. Therefore in a Smart City environment sensor data can be gathered by using powerful sensors on mobile devices(smart-phones), static sensors or vehicular sensors that rely on heterogeneous and changing network infrastructure. This paper presents one possible approach to build such network infrastructure where vehicular networks, augmented with existing city’s WiFi network, can be used to transmit (relay) and gather sensor data.
