This paper investigates the INTERSECTION Framework’s ability to build resilience into Wireless Sensor Networks. The framework’s general details are examined along with general approaches to protection against misbehaving WSN nodes. Three different approaches to remediation were implemented and tested on a TinyOS network for their different operating characteristics.

This paper describes a solution for nodes and message authentication problems in wireless sensor networks, this solution allows effectively avoiding node-impersonation and messaging falsification among the WSN nodes. The resulting protocol address authentication at two level using identity based cryptography and message authentication codes with SHA-1, for node and message authentication respec...

Applications for wireless sensor networks are often developed in integrated development environments and tested and debugged in simulators. Since development environments and simulators normally use their own user interface, it is often hard for developers to link a bug found in the simulation to the correct position in the source code. This thesis comes up with a way to debug TinyOS applicatio...

Long-term data gathering with Wireless Sensor Networks (WSNs) requires drastic optimization of power consumption to provide a long system lifetime, especially for battery operated motes. In this work, we discuss Harvester, a low power data collection application that leverages recent advancements over the standard MAC and network layer components provided by the TinyOS-2.x operating system. Mor...

Programming support for multi-threaded applications on embedded microcontroller platforms has attracted a considerable amount of research attention in the recent years. This paper is focused on this problem, and presents UnStacked C, a source-to-source transformation that can translate multithreaded programs into stackless continuations. The transformation can support legacy code by not requiri...

Energy is the most limiting resource in sensor networks. This is particularly true for dynamic sensor networks in which the sensor-net application is not statically planned. We describe three components of our energy management system for nodes in such dynamic sensor networks: A flexible energy model and an accounting infrastructure for making sensor nodes energy-aware, and Resource Containers ...

Recognizing user activities using body-worn, miniaturized sensor nodes enables wearable computers to act contextaware. This paper describes how online activity recognition algorithms can be run on the SensorButton, our miniaturized wireless sensor platform. We present how the activity recognition algorithms have been optimized to be run online on our sensor platform, and how the execution can b...
