To satisfy the high data demands in future cellular networks, an ultra-densification approach is introduced to shrink coverage of base station (BS) and improve frequency reuse. The gain capacity expected but at expense increased interference, frequent handovers (HOs), HO failure (HOF) rates, delays, increase ping pong rate, energy consumption, overheads due HO, packet losses bad user experience mostly high-speed equipment (UE) scenarios.

<title>ABSTRACT</title> <p>The Controller Area Network (CAN) protocol is still a de-facto standard for in-vehicle communication between Electronic Control Units (ECUs). The CAN lacks basic security features such as absence of sender node information, authentications mechanism and the plug play nature network. payload in data packet very small i.e. 8 bytes, therefore, implementation cryptographic solutions integrity verification not feasible. Various methods have been...

The Controller Area Network (CAN) bus serves as a legacy protocol for in-vehicle data communication. Simplicity, robustness, and suitability real-time systems are the salient features of CAN protocol. However, it lacks basic security such massage authentication, which makes vulnerable to spoofing attacks. In network, linking packet sender node is challenging task. This paper aims address this issue by developing framework link each its source. Physical signal attributes received consisting...
As 5th Generation research reaches the twilight, community must go beyond 5G and look towards 2030 connectivity landscape, namely 6G.
