Medium Access Control Protocols for Wireless Sensor Networks with Energy Harvesting
Fabio Iannello, Osvaldo Simeone, Umberto Spagnolini
The design of Medium Access Control (MAC) protocols for wireless sensor networks (WSNs) has been conventionally tackled by assuming battery-powered devices and by adopting the netw…
Heegard-Berger and Cascade Source Coding Problems with Common Reconstruction Constraints
Behzad Ahmadi, Ravi Tandon, Osvaldo Simeone +1
For the HB problem with the CR constraint, the rate-distortion function is derived under the assumption that the side information sequences are (stochastically) degraded. The rate-…
Distributed and Cascade Lossy Source Coding with a Side Information "Vending Machine"
Behzad Ahmadi, Osvaldo Simeone
Source coding with a side information "vending machine" is a recently proposed framework in which the statistical relationship between the side information and the source, instead…
Source Coding When the Side Information May Be Delayed
Osvaldo Simeone, Haim H. Permuter
For memoryless sources, delayed side information at the decoder does not improve the rate-distortion function. However, this is not the case for more general sources with memory, a…
Robust Coding for Lossy Computing with Receiver-Side Observation Costs
Behzad Ahmadi, Osvaldo Simeone
An encoder wishes to minimize the bit rate necessary to guarantee that a decoder is able to calculate a symbolwise function of a sequence available only at the encoder and a sequen…
Robust Coding for Lossy Computing with Observation Costs
Behzad Ahmadi, Osvaldo Simeone
An encoder wishes to minimize the bit rate necessary to guarantee that a decoder is able to calculate a symbol-wise function of a sequence available only at the encoder and a seque…
