A prediction based control scheme for networked systems with delays and packet dropouts
— We present a networked control scheme which uses a model based prediction and time-stamps in order to compensate for delays and packet dropouts in the transmission between sens...

A Reduced-Complexity PTS-Based PAPR Reduction Scheme for OFDM Systems
In this paper, a reduced-complexity partial transmit sequences (PTS) scheme is proposed to resolve the intrinsic high peak-to-average power ratio (PAPR) problem of orthogonal frequ...

A dynamic operating system for sensor nodes
Sensor network nodes exhibit characteristics of both embedded systems and general-purpose systems. They must use little energy and be robust to environmental conditions, while als...

A Predictive Location Based Relaying scheme for hybrid Cellular and Ad-hoc Systems
We propose a predictive location based relaying for hybrid cellular and ad-hoc systems that can provide interference minimization to uplink transmission. In the case of dense netw...
