Plug-in hybrid electrical vehicles (PHEVs) that can use both gas and electricity have the potential to greatly reduce air pollution from vehicles. In this paper, we consider a bus system where the buses are PHEVs, and some charging points at the bus stops are connected to a central energy storage (CES) via underground cables. The CES is charged by renewable energy sources and the buses get electricity...
Using electrical vehicles (EV) in transportation systems is more cost effective and environmental friendly than using conventional vehicles. In addition, the energy storage capability and mobility of EVs provide a convenient way to transfer energy from renewable energy sources to locations that have no direct access to renewable energy. As an example, an EV can be charged by a renewable energy source...
The security of Wireless Sensor Networks (WSNs) has a direct reliance on secure and efficient key management. This leaves key management as a fundamental research topic in the field of WSNs security. Among the proposed key management schemes for WSNs security, LEAP (Localized Encryption and Authentication Protocol) has been regarded as an efficient protocol over the last years. LEAP supports the establishment...
