This thesis presents hardware and software systems for creating efficient and versatile wireless sensor networks. We design and build two different hardware sensor nodes for implementing a two-tiered heterogeneous network. The first node is a variation of an existing wireless sensor node developed at Tyndall, the 25mm node. We develop a new layer with a microcontroller and a radio transceiver operating in the 433MHz frequency band. This node has a processor that has enough computational power to handle tasks such as routing in large networks, and digital signal processing. The second node is an entirely new node with a 10mm form factor. The microcontroller on the 10mm node has less memory, so cannot perform the complex tasks the 25mm node can. However, it is more energy efficient, and less expensive. Hence, it can be used in greater numbers. Our heterogeneous network is based on clusters of 10mm nodes, with a 25mm node acting as the head of the cluster, and forming the backbone of the network. Heterogeneous wireless sensor networks create new challenges for software systems. The complexity of writing an application increases due to multiple hardware architectures. To help solve these, this thesis introduces a method for quickly creating heterogeneous applications where each node can run different code. This is achieved using a parameterised library of code to synthesise specific applications, based on high-level application configuration scripts. Another challenge in wireless sensor networks, especially in heterogeneous ones, is the energy cost of reprogramming nodes. This is necessary to change the application or fix errors that have been found after the network has been deployed. Using algorithms based exploiting similarities between the application currently running and the new application, the amount of data that has to be sent in order to update the nodes is greatly reduced.

This book presents an examination of the middleware that can be used to configure and operate heterogeneous node platforms and sensor networks. The middleware requirements for a range of application scenarios are compared and analysed. The text then defines middleware architecture that has been integrated in an approach demonstrated live in a refinery. Features: presents a thorough introduction to the major concepts behind wireless sensor networks (WSNs); reviews the various application scenarios and existing middleware solutions for WSNs; discusses the middleware mechanisms necessary for heterogeneous WSNs; provides a detailed examination of platform-agnostic middleware architecture, including important implementation details; investigates the programming paradigms for WSNs, and for heterogeneous sensor networks in general; describes the results of extensive experimentation and testing, demonstrating that the generic architecture is viable for implementation on multiple platforms.

In the last years, wireless sensor networks (WSNs) are acquiring more importance as a promising technology based on tiny devices called sensor nodes or motes able to monitor a wide range of physical phenomenon through sensors. The severe hardware restrictions of sensor nodes in relation to computation, communication and specifically, energy, have posed new technical and conceptual challenges. In particular, research is moving towards heterogeneous networks that will contain different devices running custom WSN operating systems. Operating systems specifically designed for sensor nodes are intended to efficiently manage the hardware resources and facilitate the programming. Nevertheless, they often lack the generality and the high-level abstractions expected at this abstraction layer. The book address the problem of designing and implementing a generic sensor node-centric architecture distinguishing clearly the different abstraction levels in a sensor node. Programming language extensions have to be also specified on top of the architecture, in order to write portable applications. In this way, architecture deals with the problem of heterogeneity and portability.
