introduced, and new topologies are developed.

An analysis of the security of real time data diffusion-a protocol for routing in wireless sensor networks-is provided, along with various possible attacks and possible countermeasures. Third, we present preliminary feedback of the eLabBench based on a ongoing deployment in a bio- logy laboratory, and propose a design space definition for the design of single-user, work-oriented, tabletop systems.īuilding Wireless Sensor Networks: Application to Routing and Data Diffusion discusses challenges involved in securing routing in wireless sensor networks with new hybrid topologies. Second, we describe the eLabBench, including a simple implementation of activity-based computing for tabletop environments, with support for activity roaming, note-taking, and hybrid objects. This paper focuses on the eLabBench’s design, and presents three main contributions: First, based on observations we highlight a set of characteristics digital benches should support in a laboratory.

At the bench, biologists can pull digital re- sources, annotate them, and interact with hybrid (tangible + digital) objects such as racks of test tubes. TheeLabBench allows biologists to organize their experiments around the notions of activities and resources, and seamlessly roam in- formation between their office computer and the digital laboratory bench. We present theeLabBench– a tabletop system supporting experimental research in the biology laboratory.
