Wireless sensor networks are commonly used to remotely and automatically monitor environments.<br/>One of the main challenges in wireless sensor networks is to use the limited available energy as efficiently as possible, to ensure longevity of the network. For such networks to survive their intended deployment period no energy may be wasted on...

For energy management in wireless sensor networks, only the sensors with most informative measurements are activated to operate. How to select sensors that make good tradeoff between performance and energy consumption is what many researchers are focusing on. Existing solutions assume analog data model, i.e., the data from sensors collected by a...

Ambient energy-harvesting technology is a promising approach to keep wireless sensor networks (WSNs) operating perennially. Depending on the harvesting source, nodes can either be active (alive) or inactive (dead) at any instant in such Energy-Harvesting WSNs (EH-WSNs). Thus, even in a static deployment of EH-WSNs, the network topology is no...

In recent years, there is an increasing interest in the scientific community for development of algorithms targeting large-scale networks. In addition to their sheer size, these networks also exhibit various topology dynamics -- nodes join and exit at high rates (churn), are mobile and are not always reliable. Such extreme properties make...

Traditionally, link quality estimation (LQE) has been viewed as an a priori step in sensor network routing protocols because it filters out unreliable links before data transmission. Recent results, however, show that protocols can perform well without a priori LQE. Because getting rid of LQE seems rather counter-intuitive, the aim of this work...

Accurate time synchronization is crucial for many applications of Wireless Sensor Networks. Extensive research is performed on this topic, however, there are some aspects of time synchronization which still require attention. In this thesis we investigate aspects of the network which influence the accuracy of packed based time synchronization in...

We can foresee a near-future scenario where a huge number of semi-intelligent devices are part of our everyday environment, our homes, the public places and the office as well. The intelligent thermostat uploads the temperature readings to an online database; the fridge sends a tweet when we are out of milk; the coffee machine texts us when the...

The number of wireless sensor networks is constantly increasing. In the deployment phase of the WSNs projects it is common for failures to appear. These can be caused by software or hardware faults or by environmental factors. In order to find the source of these problems, the WSN needs to be inspected. Since the deployments of WSN are often...

In recent years, large-scale systems have become mainstream at a very high pace. Typical examples of large-scale systems are MANETs, Wireless Sensor Networks, Pervasive Computing, Swarm Robotics, etc. These systems distinguish them- selves by the large number of devices they embody, and emergent behaviors they exhibit: Behavior that is globally...

In the development of wireless sensor networks, power consumption is one of the bottlenecks for wide applications. In order to improve the energy efficiency of wireless sensor networks, a wakeup radio scheme is presented. The main transceiver that is responsible for data communication is in the sleep mode most of the time. An additional device...

Wireless sensor networks (WSNs) are ad-hoc wireless networks of small form-factor embedded nodes with limited memory, processing, and energy resources. Certain applications, like security and art monitoring,require reliable data transport. Current work for WSNs only provides stochastic reliability or guaranteed reliability for bulk transfer....

Model-based diagnosis is a technique where a model of a system is combined with observations from that system, to generate diagnoses for failures of the system. This thesis looks at how model-based diagnosis can be applied to wireless sensor networks (WSNs). WSNs are ad-hoc wireless networks of small form-factor, embedded nodes with limited...
