Instrumenting the physical world through large networks of wireless sensor nodes, particularly for applications like environmental monitoring of water and soil, requires that these nodes be very small, light, untethered and unobtrusive. The problem of localization, i.e., determining where a given

methodology for systematic advance. To this end, we identify key requirements, develop a small device that is representative of the class, design a tiny event-driven operating system, and show that it provides support for efficient modularity and concurrency-intensive operation. Our operating system fits

Handheld computers and small devices that present users a visible software interface are not a new concept, but I found that research in this field has increased significantly within the last several years. I think part of this can be attributed to major reductions in the cost of manufacturing

In sensor networks [ASSC02] - and also other environments with small devices - the classical client/server co-operation paradigm does no longer seem to be adequate for a number of reasons: (1) Sensor nodes communicate via unreliable wireless media

Abstract. One of the most basic requirements in software architectures for pervasive computing is the ability to adapt to changes. Although there is an increasing number of applications for small devices such as mobile telephones, the software used is still very restricted in terms of its

to small devices, like mobile phones, as well as taking advantage from the benefits of a desktop computer. The

information from beacons spread throughout the building. Cricket is the result of several design goals, including user privacy, decentralized administration, network heterogeneity, and low cost. Rather than explicitly tracking user location, Cricket helps devices learn where they are and lets them decide whom

The cognitive dimensions framework is a broad-brush evaluation technique for interactive devices and for non-interactive notations. It sets out a small vocabulary of terms designed to capture the cognitively-relevant aspects of structure, and shows how they can be traded off against each other
