Vast majority of wireless appliances used in household, industry and medical field share the ISM frequency band. These devices need to coexist and thus are challenged to tolerate their mutual interference. One way of dealing with this is by using frequency hopping; where the device changes its

Abstract—Mathematical models play a pivotal role in understanding and designing advanced low-power wireless systems. However, the distributed and uncoordinated operation of traditional multi-hop low-power wireless protocols greatly complicates their accurate modeling. This is mainly because

I first thank my thesis advisors Thiemo Voigt and Adam Dunkels for being my excellent advisors, and also for being the great colleagues you still are. Thiemo and Adam have complemented each other superbly, giving me feedback, perspectives, insights, and having made every single new venture truly fun. My deepest thanks also go to my professor Per Gunningberg, Uppsala University. Per has in a seemingly easy way spotted erroneous assumptions, has valued my research contributions, and has connected my own work with another broader world of research. I want to thank all colleagues in the Networked Embedded Systems group:

ABSTRACT Generative House is a collaborative exploration of advanced technologies for lower-and working-class housing carried out by industrial and academic partners in southern Brazil. It seeks to test generative procedures and digital manufacturing to develop a flexible building system for low-cost

demand side agents who are less sensitive to supply assurance, seller reputation, inspection, etc., but hurts local (specialized) stores, and with it agents who continue to buy locally. • Entry in a geographical market of a large discount store: it attracts agents who value low prices but less so high

validation: a protocol can use data traffic as active topology probes, quickly discovering and fixing routing loops. The second is adaptive beaconing: by extending the Trickle code propagation algorithm to routing control traffic, a protocol sends fewer beacons while simultaneously reducing its route repair

This paper examines whether cross-listing in the U.S. reduces foreign firms ’ cost of capital. While prior studies document that U.S. cross-listings are associated with substantial increases in firm value, the sources of these valuation effects are not well understood. We estimate the cost

in multiple applications, remote configuration, and actuation is still a big challenge. The purpose of this paper is to analyse and describe which mobility support can best be used in different scenarios, and how shared usage of mobile WSANs by multiple IP applications can best be scaled up.
