Routing under energy harvesting constraints is considered. A routing protocol based on Dijkstra’s global routing algorithm is proposed and evaluated. The protocol dynamically modifies routing trees based on available energy accumulated through energy harvesting. Channel-state information is gathered in typical indoor environments using two experimental setups; one with eight nodes and on-body a...

In this paper, we generalize conventional time division multiple access (TDMA) wireless networks to a new type of wireless networks coined generalized wireless powered communication networks (gWPCNs). Our prime objective is to optimize the design of g-WPCNs where nodes are equipped with radio frequency (RF) energy harvesting circuitries along with constant energy supplies. This constitutes an i...

Providing a constant and perpetual energy source is a key design challenge for implantable medical devices. Harvesting energy from the human body and the surrounding is one of the possible solutions. Delivering energy from outside the body through different wireless media is another feasible solution. In this monograph, we review different stateof-the-art mechanisms that do “in-body” energy har...

Typically two configurations are used for energy harvesting with different advantages: piezoelastic and piezomagnetoelastic. Best performance of the piezoelastic configuration is when the excitation frequency is close to the resonance frequency. If the input frequency slightly deviates from the natural frequency, the generated power is severely decreased. To tackle the problem, the piezomagneto...

The primary challenge in wireless communication with energy harvesting devices is to efficiently utilize the harvesting energy such that the data packet transmission could be supported. This challenge stems from not only QoS requirement imposed by the wireless communication application, but also the energy harvesting dynamics and the limited battery capacity. Traditional solar predictable energ...

Piezoelectric materials can be used to convert oscillatory mechanical energy into electrical energy. Energy harvesting devices are designed to capture the ambient energy surrounding the electronics and convert it into usable electrical energy. The design of energy harvesting devices is not obvious, requiring optimization procedures. This paper investigates the influence of pattern gradation usi...

The Wireless sensor networks have been deployed in an wide range of applications in environmental monitoring, target tracking, etc. The sensor networks have an major problem concerned with energy efficiency and lifetime of the network. The Energy consumed by the nodes should be less which prevents the earlier death of sensor nodes due to drained energy level. Several techniques have been used t...
