Despite intense research on wireless sensor networks (WSN) in the last two decades,
programmers still do not have a cohesive and expressive application programming interface …

In this paper we discuss the design methodology based on the service-oriented architecture
and agile development principles for wireless embedded and sensor networks (WSNs). This …

We present the Unified Link Layer API (ULLA) framework: an open and extensible API
framework that incorporates a number of requirements related to a wide range of …

Wireless sensor networks are characterized by a large number of non-standardized
protocols and varying application requirements. This creates need for a systematic approach …

We describe a novel geometric localised routing protocol in disruption (delay) tolerant
network (DTN). Although DTNs do not guarantee the connectivity of the network all the time …

Various emerging applications enabled by wireless sensor networks demand new and
versatile MAC algorithms. These MAC protocols should be able to adapt to varying …

Cognitive radio networks require reconfiguration and adaptivity in order to efficiently meet
the changing application demands and network conditions. We have developed a …

Wireless networks are becoming ubiquitous. They have numerous applications also outside
the cellular systems, for example in agriculture, multi-user games, health monitoring using …

The diversified applications of wireless sensor networks impose different types of
requirements on MAC protocols. Therefore, it has become increasingly important to be able …

We present the design and implementation of UDAE, a universal data access engine for
wireless sensor networks. The UDAE allows developers to access data both locally and over …
