The Communication Theory Lab is conducting research and education in the general area of digital communications and in wireless communications in particular. We work both with basic research and with more applied problems, often in collaboration with industry. More information about us is available on the Internet: www.commth.ee.kth.se.
In particular the following research areas are relevant to the position: Cognitive radio, spectrum sensing and dynamic radio resource allocation, Cooperative coding and transmission techniques in wireless sensor networks, Wireless communications in automatic control, Information theory for wireless communications.

A wireless surveillance network will be used to monitor the nesting and mating rituals of a remote North Atlantic seabird colony, providing scientists with unprecedented access to their behaviour and ecology.
Researchers from Oxford University and Microsoft Research in the UK, and from the Free University of Berlin, Germany, developed the network to monitor more than 100,000 Manx shearwater birds that breed during the summer on Skomer Island, off the west coast of Wales in the North Atlantic.
Pairs of shearwaters raise their chicks inside metre-long burrows, visiting them during the night, sometimes after fishing trips that can last several days.

The dream to turn Ossabaw Island into a living laboratory accessible to anyone with a computer is a step closer to reality. Skidaway Institute of Oceanography and the Ossabaw Island Foundation have received $200,000 in grants from the Georgia Power Corporation and the Georgia Research Alliance to build a network of sensors on the remote coastal Georgia barrier island. The goal is to allow educators, students and scientists to study the island and monitor changes in the environment from off-island locations.
“Based on a number of workshops with state scientists and other stakeholders, we initiated the idea to establish an observing system on the island so people could have access to the island, not just by going over by boat, but also remotely through sensors and computer technology,” said Herb Windom, a Skidaway Institute scientist and one of the originators of the plan.
ZigBeef has developed a novel long-range radio frequency identification (RFID) system that allows handheld devices to track numerous mobile assets. The system consists of one or more asset tags and a tag reader and can be set up in minutes. The ZigBeef tags are about the size of a pack of chewing gum. The tag reader is presently offered as a USB-stick. PDA and Smartphone interfaces are also available. In minutes, users can set up a working RFID tagging system.
ZigBeef tag systems offer new levels of convenience for asset identification. For example, a rancher using a ZigBeef reader can receive an instantaneous headcount of cattle in a pasture. A rental lot manager can take inventory of tagged vehicles immediately. Oil well site managers can log entry and exit times of vehicles or equipment at their locations.
Interesting video about the longest Sensor Networking chain, world record for the maximum number of hops.
The Computer Science department of the Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) at the University of Twente (UT) is one of the largest academic institutions in computer science in the Netherlands, with 220 faculty members and 1200 students.
The Distributed and Embedded Systems (DIES) research group of EEMCS/CTIT collaborates with a number of academic and industrial partners in the ALwEN project. The scientific goals of the ALwEN project are to cope with design complexity of large-scale Wireless Sensor Network (WSN) systems; to create adaptive network management solutions; to understand and predict overall system level properties such as energy consumption, latency and throughput; to support the effective deployment of large WSN applications by minimizing the amount of effort spent to program and debug such applications; to address the security and privacy requirements that are related to Ambient Living and health care applications with WSN systems.
We are looking for a PostDoc (three years) who will investigate key management and secure data aggregation in wireless sensor networks (vacancy number 08/016).

Driven by emerging standards, increasing energy costs, and advances with Wireless Sensor Networking (WSN), the “smart home” is becoming a reality for the mass market. This extensive investigation with over 100 home installers, vendors, and suppliers found that the wireless smart home market is accelerating. Indicators of this growth include hundreds of products currently shipping and established service providers such as AT&T and SK Telecom are starting to offer WSN based home monitoring services.
While proprietary WSN systems have been used by professional installers in luxury homes for over a decade, wireless protocols such as Z-Wave and ZigBee will make smart home solutions affordable for the average household.
With a total potential market size of 6 billion cumulative WSN nodes worldwide, the residential sector is an essential target market for wireless sensing and control solutions. Some of the largest and fastest growing smart home markets include lighting, energy management, security, entertainment control, and home health. In 2012, the Wireless Sensor Network (WSN) smart home market will be worth $2.8 billion worldwide, up from $470 million in 2007.
