To enhance transportation systems’ safety, vehicles have to periodically broadcast authenticated beacons on a dedicated limited wireless medium; beacons include vehicles’ current status. To provide the required authentication, the Public Key Infrastructure (PKI) security framework has been embraced; PKI has a significant authentication overhead that consumes the limited wireless medium. [...]

Mercury and thallium forms a eutectic alloy that finds extensive use in thermostatic devices owing to its capability of withstanding extremely low temperature. As both these metals are highly toxic, so herein we report their co-sensing on a sensitive electrochemical platform. The performance of the designed sensing surface was tested [...]

Use of the helmet is beneficial in reducing the severity of injuries and avoiding fatalities for motorcyclists, therefore, legislation exists in almost all countries. In practice, the situation is different regarding the helmet use, especially in the developing countries. This paper investigates the helmet use behavior of motorcyclists in Karachi, [...]

To defend intelligent transportation networks’ security and privacy, existing standards employ the Public Key Infrastructure (PKI) authentication framework. However, the high associated PKI computation and communication overheads break ground for utilizing an alternative candidate, the Identity-based Cryptographic (IBC) authentication. Most of the underlined calculations of the IBC approaches rely on [...]

The global and continental crash death rate trends, adjusted for under-reporting, death definition, and missing data, are analyzed, modelled, and compared with international findings considering data for 215 countries for 35 years. Although global reported mortality rates required 25% to 44% adjustments, that estimated by World Health Organization (WHO) and World [...]

While there has been an increasing number of studies on smart cities, there are still issues in assessment and governance of these cities. This study aims to analyze and provide insights into the research done in smart city maturity models by conducting a systemically review of related literature. The study [...]

Generation system reliability is an important factor in the long-term planning for future capacity expansion to make sure that the total installed capacity is enough to support demand. This case is very important for smart cities, because it is focusing on the optimal solution. Whenever the number of days very [...]

Internet of things (IoT) could be found on everywhere in today live. It is used in smart cities like roads, hospitals and in smart homes like controlling door or air conditioner unit or preventing fires and much more. These devices that use IoT are connected to the internet and send [...]
