Capacity-achieving encoding for the broadcast erasure channel with multiple users
(2011)We consider the N-user memoryless broadcast erasure channel with N unicast sessions (one for each user) where receiver feedback is sent to the transmitter in the form of ACK/NACK messages. We first provide a generic outer ... -
Cooperative Speed Estimation of an RF Jammer in Wireless Vehicular Networks
(2020)In this paper, we are concerned with the problem of estimating the speed of an RF jammer that moves towards a group/platoon of moving wireless communicating nodes. In our system model, the group of nodes receives an ... -
Demonstration of a video-aware multicast opportunistic routing protocol over 802.11 two-hop mesh networks
(2014)In this demo paper, we demonstrate and evaluate a novel Opportunistic Routing (OR) protocol for video multicast, namely Video-aware Multicast Opportunistic Routing (ViMOR), over 802.11 two-hop mesh networks. OR exploits ... -
Distributed Estimation in Wireless Sensor Networks with an Interference Canceling Fusion Center
(2016)In this paper, we consider Distributed Estimation (DES) in a Wireless Sensor Network (WSN) and assume that the number of sensors in the WSN is larger than the available number of transmission slots. With classic DES, the ... -
An Efficient Localization and Avoidance Method of Jammers in Vehicular Ad Hoc Networks
(2022)Jamming is a terrifying attack that could harm 802.11p-based vehicular communications by occupying the communication channels by overwhelming the network with jamming packets, especially for self-driving cars, as it is ... -
Estimating the Relative Speed of RF Jammers in VANETs
(2019)Vehicular Ad Hoc Networks (VANETs) aim at enhancing road safety and providing a comfortable driving environment by delivering early warning and infotainment messages to the drivers. Jamming attacks, however, pose a significant ... -
Lossy transmission of correlated sources in a multiple access quasi-static fading channel
(2016)In this paper, we investigate low-complexity, receiver-driven strategies for the transmission of two correlated sources in a multiple access quasi-static fading channel. We consider two different transmission modes at the ... -
Low-complexity beamforming techniques for IEEE 802.11n WLANs
(2009)The impetus of the present study is to describe a downlink beamforming method that increase spectrum efficiency and significantly reduces implementation complexity and power consumption compare to beamforming technique at ... -
Optically-Enabled Bloom Filter Label Forwarding Using a Silicon Photonic Switching Matrix
(2017)Simplified forwarding schemes relying on Bloom filter (BF)-based labels emerge as a promising approach for coping with the substantial increase in lookup table memory requirements associated with the growing number of ... -
Performance of an Underwater Optical Wireless Link with a Randomly Placed or Moving Receiver
(2021)The current work investigates the outage probability of a vertical diffused line-of-sight underwater optical wireless communication link where a fixed transmitter at the sea surface communicates with a receiver floated ... -
RF Jamming Classification Using Relative Speed Estimation in Vehicular Wireless Networks
(2021)Wireless communications are vulnerable against radio frequency (RF) interference which might be caused either intentionally or unintentionally. A particular subset of wireless networks, Vehicular Ad-hoc NETworks (VANET), ... -
Secrecy in wireless communication through closed-loop receiver de-synchronization
(2020)A subset of the synchronization algorithms in a wireless receiver are responsible for tracking the phase and frequency of a digitally modulated signal. If variations of the phase in the signal are substantial, then the ... -
Stochastic comparisons for a static routing problem with resequencing
(2004)In communication networks, packets from the same source-destination pair may be routed along several paths and arrive at their receiver out of order. This often necessitates the use of a resequencing buffer at the destination. ...
