A hybrid access method for broadcasting of safety messages in IEEE 802.11p VANETs
EURASIP Journal on Wireless Communications and Networking, 2021 Vehicular Ad-hoc Networks (VANETs) can improve the road safety by transmitting safety-critical messages such as beacons and emergency messages. IEEE 802.11p VANETs have adopted the carrier sense multiple access with collision avoidance (CSMA/CA ...

Erasure Broadcast Channels With Intermittent Feedback [PDF]
IEEE Transactions on Communications, 2021 Achievable data rates in wireless systems rely heavily on the available channel state information (CSI) throughout the network. However, feedback links, which provide this information, are scarce, unreliable, and subject to security threats. In this work, we study the impact of having intermittent feedback links on the capacity region of the canonical ...

On the user selection for MIMO broadcast channels [PDF]
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005 In this paper, a downlink communication system, in which a Base Station (BS) equipped with $M$ antennas communicates with $N$ users each equipped with $K$ receive antennas, is considered. An efficient suboptimum algorithm is proposed for selecting a set of users in order to maximize the sum-rate throughput of the system. For the asymptotic case when $N$

Coded caching for wiretap broadcast channels [PDF]
2017 IEEE Information Theory Workshop (ITW), 2017 The paper studies the wiretap erasure broadcast channel (BC) with an external eavesdropper when the legitimate receivers have cache memories. Various secure coding schemes are proposed for a scenario where K w weak receivers have same erasure probabilities and K s strong receivers have same erasure probabilities.

Capacity Bounds for Broadcast Channels with Confidential Messages [PDF]
, 2008 In this paper, we study capacity bounds for discrete memoryless broadcast channels with confidential messages. Two private messages as well as a common message are transmitted; the common message is to be decoded by both receivers, while each private message is only for its intended receiver.
