This paper proposes an effective warning message forwarding scheme for cooperative collision avoidance. In an emergency situation, an emergency-detecting vehicle warns the neighbor vehicles via an emergency warning message. Since the transmission range is limited, the warning message is broadcast in a multihop manner. Broadcast packets lead two challenges to forward the warning message in the v...

Electric vehicles (EVs) are being introduced by different manufacturers, thanks to their environment-friendly perspective alleviate CO 2 pollution. In this paper, the proposed EV charging management scheme enables pre-empted service for heterogeneous EVs (depends on capabilities, brands, etc.). ...

Intelligent Transportation Systems (ITS) have been developed to improve the efficiency and safety of road transport by using new technologies for communication. Vehicle (V2V) Infrastructure (V2I) are a subset ITS widely used solve different issues associated with transportation in cities. Road traffic congestion is still most significant problem that causes important economic productivity damag...

Recent advances in vehicle connectivity have allowed formation of autonomous platoons for improved mobility and traffic throughput. In order to avoid a pile-up such platoons, it is important ensure platoon (string) stability, which the focus this work. As per conventional definition string power (2-norm) spacing error signals should not amplify downstream platoon. But practice, infinity-norm si...

Cellular vehicle to everything (C-V2X) is a technology achieve networking, which can improve traffic efficiency and safety. As special network, the C-V2X system faces many security risks. The (V2V) communication transmits condition data, driving path user habits so on. It necessary ensure opposite equipment registered (installed in vehicle), data transmitted between secure. This paper proposes ...

Vehicle-to-vehicle (V2V) communication is a technology that can wirelessly exchange information on the speed and position of nearby vehicles, helping to avoid collisions, alleviate traffic congestion, improve environment. The 3rd Generation Partnership Project (3GPP) has specified methods reliability V2V sidelink (SL) by implementing hybrid automatic repeat request (HARQ) in casting strategy co...
