In this paper, we analyze various energy efficient routing protocols to improve the lifetime of wireless sensor networks. WSNs are composed of a large number of sensor nodes which have limited energy. Energy conservation is a very critical issue to design energy efficient routing techniques in wireless sensor networks. The paper reviews the traditional energy […]

An improved cluster head selection approach for energy efficiency in wireless sensor networks: A review
High step-up voltage gain dc-dc converters are widely applied in fuel cell stacks, photovoltaic arrays, battery sources, and high intensity discharge lamps power systems. Active-network converters with coupled inductors (CL-ANC) are derived from switched inductor active-network converters (SL-ANC). The proposed converter contains two coupled inductors which can be integrated into one magnetic core and two […]

Experimental Control and Design of Low-Frequency Bias Networks for Dynamically Biased Amplifiers
To reach the video bandwidth requirements on the supply paths, power amplifiers with dynamic bias schemes are constrained to reduce the values of the low-frequency (LF) decoupling capacitors on their bias lines. This can entail a decrease of the LF stability margins, among other negative effects. In this work, a methodology is proposed to experimentally […]
Read moreWe demonstrate a cross-layer orchestration for packet service over IP-optical networks, in terms of availability and elasticity. Our orchestration built over the SDN concept self-adjusts and cost-efficiently responds to dynamics on network paths, impairments/failures, and topology.
