Wireless sensor network WSN nodes called motes are small wireless embedded devices. They suffer from limitations of their power supplies and available bandwidth as well as in their memory and computational power. As a promising approach, network coding NC provides means of relaxing the combined problem of limited supplies and bandwidth. We present...
Conference Paper
Wireless sensor networks (WSNs) consist of wirelessly communicating nodes with an autarkic power supply for each node. Typically, the consumable energy of these nodes is very limited. Energy harvesting systems (EHSs) can be used to extend the lifetime or even enable perpetual operation of the sensor nodes. Applicable energy-aware WSN protocols and...

Wireless sensor networks (WSNs) are power critical systems, because they are used in application areas without wired infrastructure. Each sensor node needs a dedicated power supply. Today's protocols and applications for WSNs are often power-aware. However, the state-of-charge (SoC) estimation of the energy storage component (e.g. rechargeable batt...

Wireless sensor networks (WSNs) suffer from the lack of wired infrastructure. Each node needs its own power supply, e.g. batteries or energy harvesting systems (EHSs). Typically, EHSs can extend the lifetime of a sensor node or even enable perpetual operation. Due to the high variation of harvestable energy of the environment, the design of the EHS...

Conference Paper
Energy harvesting systems (EHSs) are the key to perpetual operation of electronic devices in application areas with bad infrastructure or mobility. Wireless sensor networks (WSNs) are often used in such areas. Normal WSN nodes are powered by batteries.

Conference Paper
Energy efficiency is very important for mobile devices and wireless sensor networks (WSNs), because the consumable energy is limited. Therefore, the operating time of such devices depends mainly on the capacity of the energy storage component and on the average power consumption of the device. The power consumption depends on the supply voltage and...

Large scale deployments of small, wireless, networked, embedded systems demand for cost reduction in development and maintenance.

Wireless sensor network (WSN) motes are resource constrained devices. Especially, bandwidth and energy are scarce resources. Therefore, lots of effort is put into the optimization of low-power networking protocols. While network control overhead is an issue for many to most of such protocols, we present an approach that is virtually overheadfree. W...

The performance of embedded systems often suffers from strict cost/size and power/energy limitations. This is especially important for very small systems that are sold in a high number of items like smart cards and RFID controllers. On one hand, small hardware platforms are developed to minimize cost and power consumption. On the other hand, applic...

Network coding is a suitable mean to come up against the effects of crossing information flows in wireless sensor networks (WSNs) where these areas are heavily impacted in terms of channel bandwidth, message delay and energy balance.
