Low cost networks of wireless sensors can be distributed to provide information about an environment. Even a network of sensors providing scalar measurements (for instance, of temperature) presents both formidable challenges in terms of integrating and interpreting measurements over space and time

radio channel periodically. Consequently, communications will not suffer from the same interference each time; instead, it should be fairer and more stable. This thesis investigates the aforementioned problem in the field of low power wireless sensor networks and Internet of Things where Contiki OS

This paper describes the design of a low-cost, low-power smart imaging core that can be embedded in cameras. The core integrates an ARM 9 processor, a camera interface and two specific hardware blocks for image processing: a smart imaging coprocessor and an enhanced motion estimator. Both

A successful person tracking system, must not only perform visual analysis robustly, but also be small, cheap and consume relatively little power. The TYZX Embedded 3D Vision systems are perfectly suited to provide the low power, small footprint

For MMOGs with higher realtime requirements and/or a smaller number of customers willing to pay, peer-to-peer networking seems to be a

This dissertation presents three novel programming models and middleware systems that address these challenges: Limone, Agilla
