Coded Cooperation for Multiway Relaying in Wireless Sensor Networks

Sensors, 2015
Wireless sensor networks have been considered as an enabling technology for constructing smart cities. One important feature of wireless sensor networks is that the sensor nodes collaborate in some manner for communications.

Impact of Interference in Coexisting Wireless Networks with Applications to Arbitrarily Varying Bidirectional Broadcast Channels

Entropy, 2012
The paradigm shift from an exclusive allocation of frequency bands, one for each system, to a shared use of frequencies comes along with the need of new concepts since interference will be an ubiquitous phenomenon.

Drought Disasters in China from 1991 to 2018: Analysis of Spatiotemporal Trends and Characteristics

Remote Sensing, 2023
Droughts have emerged as a global problem in contemporary societies. China suffers from different degrees of drought almost every year, with increasing drought severity each year. Droughts in China are seasonal and can severely impact crops.

Secrecy Capacity Region of Fading Broadcast Channels

, 2007
The fading broadcast channel with confidential messages (BCC) is investigated, where a source node has common information for two receivers (receivers 1 and 2), and has confidential information intended only for receiver 1.

Unconstrained distillation capacities of a pure-loss bosonic broadcast channel [PDF]

, 2016
Bosonic channels are important in practice as they form a simple model for free-space or fiber-optic communication. Here we consider a single-sender two-receiver pure-loss bosonic broadcast channel and determine the unconstrained capacity region for the ...

Modelling Regional Airport Terminal Capacity

Procedia Engineering, 2017
Abstract Effectiveness of operation and avoiding of over-design of infrastructure become key factors for ensuring regional airports’ existence at the beginning of the 21st century in Europe. Due to the operational profile, regional airports in Europe have a limited capability to increase the non-aviation revenue.

The Arbitrarily Varying Multiple-Access Channel with Conferencing Encoders

, 2012
We derive the capacity region of arbitrarily varying multiple-access channels with conferencing encoders for both deterministic and random coding. For a complete description it is sufficient that one conferencing capacity is positive.
