Abstract: The Over the past decade, metropolitan cities have witnessed a hive of activity leading to sustained levels of air pollution. The five prime pollutants are Carbon Monoxide (CO), Particulate Matter (PM), Nitrogen oxides, Sulphur dioxide (SO2) and ozone (O3). The air contaminates when these pollutants commingle, making it lethal to mankind. The inception of blockchain and VANET have paved its way to a variety of prospects including medicine, economics, internet of things and software engineering to name a few. The data collected from humans close to smart vehicles, connected to the Wireless Body Sensor Network (WBSN), is sent to the assessing module. The system learns nothing about the data being processed. In this paper blockchain with an additional layer of security has been proposed for an infrastructure less environment. In order to address one among many risks involved in the block chain framework, threshold cryptography scheme has been included to further suite ad hoc environment. The secret key is not trusted with any particular node but distributed.
