Performance Analysis of MAC for Power-Line Communications

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

We investigate the IEEE 1901 MAC protocol, the dominant protocol for high data rate power-line communications. 1901 employs a CSMA/CA mechanism similar to – but much more complex than – the backoff mechanism of 802.11. Because of this extra complexity, and ...

Switched Local Schedules for Diamond Networks

Christina Fragouli, Siddhartha Brahma, Ayan Sengupta

We consider a Gaussian diamond network where a source communicates with the destination through

n

non-interfering half-duplex relays. We focus on half-duplex schedules that utilize only local channel state information, i.e., each relay has access to its ...

A Multipurpose Testbed for Full-Duplex Wireless Communications

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic

Unlike in the traditional half-duplex (HD) mode of transmission over a wireless link, in the full-duplex (FD) mode both terminals receive and transmit on the same frequency band, simultaneously. Hence, FD gives us up to twice the spectral efﬁciency of HD, ...

Physical-layer Network Coding on the Random-access Channel

Michael Christoph Gastpar, Jasper Goseling

We consider a physical-layer network coding strat- egy for the random-access channel, based on compute-and- forward. When packets collide, it is possible to reliably recover a linear combination of the packets at the receiver. Over many rounds of transmiss ...

A Parallelized Layered QC-LDPC Decoder for IEEE 802.11ad

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Alessandro Cevrero, Nicholas Alexander Preyss

We present a doubly parallelized layered quasi-cyclic low density parity-check decoder for the emerging IEEE 802.11ad multigigabit wireless standard. The decoding algorithm is equivalent to a nonparallelized layered decoder and, thus, retains its favorable ...

Energy-Efficient Continuous Activity Recognition on Mobile Phones: An Activity-Adaptive Approach

Karl Aberer, Zhixian Yan, Dipanjan Chakraborty

Power consumption on mobile phones is a painful obstacle towards adoption of continuous sensing driven applications, e.g., continuously inferring individual’s locomotive activities (such as ‘sit’, ‘stand’ or ‘walk’) using the embedded accelerometer sensor. ...

Bringing Stability to Wireless Mesh Networks

Adel Aziz

Wireless mesh networks were designed as a mean to rapidly deliver large-scale communication capabilities without the support of any prior infrastructure. Among the different properties of mesh networks, the self-organizing feature is particularly interesti ...

Coexistence of Multiple HomePlug AV Logical Networks: A Measurement Based Study

Jean-Yves Le Boudec, Alaeddine El Fawal, Zhang Liu

HomePlug AV (HPAV) was designed to provide high speed in-home communication with 200Mbps PHY rate, with the goal to overcome various noises over power wires and to jump from one phase to a neighboring one. A HomePlug AV Logical Networks (AVLN) is defined b ...

Cross-Layer Based Analysis of Multi-Hop Wireless Networks

Tarik Tabet

In this work, we revisit classical packet radio networks with a modern treatment of physical-layer (PHY) procedures, medium-access (MAC) and geographic channel-driven routing protocols. Our network model assumes that nodes are randomly distributed on the p ...

Neighbor discovery with reception status feedback to transmitters

Ramin Khalili

Neighbor discovery is essential for the process of self-organization of a wireless network, where almost all routing and medium access protocols need knowledge of one-hop neighbors. In this paper we study the problem of neighbor discovery in a static and s ...
