Cross-Layer Energy Optimization in Cooperative Cellular Systems

Cross - Layer Optimization in Energy Constrained Networks

In this thesis we consider wireless networks with a hard energy constraint, where each node is powered by a small battery. Under this hard constraint, reducing energy consumption is the most important design consideration for such networks. Since all layers of the protocol stack contribute to the energy per bit consumed in its end-to-end transmission, energy minimization requires a joint design...

Cross-Layer Energy Optimization in Multihop

Cross - Layer Optimization and Cooperative Communications in Wireless Networks

This dissertation studies cross-layer optimization and cooperative communications in wireless networks. It consists of three main thrusts. In the first thrust, a cross-layer design approach is taken to study rate control in multi-hop wireless networks. Due to the lossy nature of wireless links, the data rate received successfully at the destination node is typically lower than the transmission ...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Cross-layer Optimization in Sensor Networks with Energy Constraints

A typical wireless sensor network consists of sensors powered by small batteries that are difficult to replace if not impossible. Hence, the sensor nodes can only transmit a finite number of bits before they run out of energy. Thus, reducing the energy consumption per bit for end-to-end data transmission is an important design consideration for such networks. We assume that each information bit...
