Ranging from full image replacement to virtual machines, a variety of mechanisms exist today to deploy new software or to fix bugs in deployed systems. However, TinyOS - the current state of the art sensor node operating system - is still limited to full image replacement as nodes execute a statically-linked system-image generated at compilation time. In this paper we introduce Dynamic TinyOS to enable the dynamic exchange of software components and thus incrementally update the operating system and its applications. The core idea is to preserve the modularity of TinyOS, i.e. its componentization, which is lost during the normal compilation process, and enable runtime composition of TinyOS components on the sensor node. The proposed solution integrates seamlessly into the system architecture of TinyOS: It does not require any changes to the programming model of TinyOS and existing components can be reused transparently. Our evaluation shows that Dynamic TinyOS incurs a low performance overhead while keeping a smaller - upto one third - memory footprint than other comparable solutions. fileadmin/papers/2010/2010-05-icc-munawar-DynamicTinyOS.pdf Online IEEE Proceedings of the IEEE International Conference on Communications (ICC), Cape Town, South Africa en 978-1-4244-6402-9 1550-3607 1 WaqaasMunawar Muhammad HamadAlizai OlafLandsiedel KlausWehrle techreport 200908munawarfgsndynamictinyos 2009 9 9-12 fileadmin/papers/2009/2009-08-munawar-fgsn-dynamic-tinyos.pdf http://doku.b.tu-harburg.de/volltexte/2009/581/pdf/proceedings.pdf Print Technical University Hamburg
