Future connected and autonomous vehicles (CAVs) must be secured against cyberattacks for their everyday functions on the road so that safety of passengers and vehicles can be ensured. This article presents a holistic review of cybersecurity attacks on sensors and threats regarding multi‐modal sensor fusion. A comprehensive review of cyberattacks on intra‐vehicle and inter‐vehicle communications is...
We consider two-user relay-aided uplink nonorthogonal multiple access (NOMA) with noisy network coding (NNC) at the relay. The NNC-based cooperation strategy at the relay relies on noisy quantization followed by joint source-channel coding, while at the destination it utilizes joint decoding using the non-orthogonal signals received from the sources and the relay. After presenting the information...
This paper presents a prototype implementation and experimental performance evaluation of compress- and-forward (CF) relaying using software-defined radios. Under QPSK transmissions from all nodes, the relay demodulates the received signal before applying distributed joint source-channel coding (DJSCC) implemented with the help of an off-the- shelf convolutional code. The destination employs two stages...
We consider layered decode-forward (DF) cooperation in a relay-aided wireless multicast network. Splitting the source-message into two equal layers, we provide unequal power allocation to the individual layers through a simple mapping operation on a QAM constellation. The layering process thus allows the destinations to partially recover the message from the source's transmissions. At the relay, we...
