The Internet of Things promises an always-connected future where the objects surrounding us will communicate in order to make our lives easier, more secure, etc. This evolution is a research opportunity as new solutions must be found to problems ranging from network interconnection to data mining. In the networking community, innovative solutions are being developed for the Device Layer of the Internet...
To enable a prosperous Internet of Things, devices and services must be extensible and adapt to changes in the environment or user interaction patterns. These requirements manifest as a set of design principles for each of the layers in an IoT ecosystem, from hardware to cloud services. This paper gives concrete guidelines learned from building a full-stack Synergistic IoT platform.
Minimizing energy-consumption is an important aspect in the creation of network stacks optimized for resource constrained embedded systems. In this abstract we present our approach of using a lightweight monitor inside the Contiki firmware to investigate energy consumption issues. We also present a first result that we obtained with this approach.
Wireless sensor network (WSN) is a technology used to collect data from different sources. The development of WSNs offer complex challenges. Developers of WSN systems should be aware of issues such as energy-efficient network management and cooperation among nodes. The advancement in sensor nodes have created new opportunities for cooperation. This paper addresses the lack of software development...
This paper introduces some concepts of WSN and Pervasive Computing, then presents AesSidhe, a WSN architecture currently under design in Instituto Tecnológico de la Laguna. The features and constraints of the hardware architecture are described, and the current work in the software architectureis described and commented. An analysis of usage of the architecture in pervasive computer systems for three...
Lately, our embedded computing research group has been working on code generation targeting small footprint and low energy consumption. In specific, we've been researching the effect of optimizations on code size. Previously, we've concluded that evaluating single optimizations does not lead to interesting results. That's due to the fact that optimization efficiency towards reducing code size is greatly...
Engineering hardware platform for a Wireless Sensor Network (WSN) node is known to be a tough challenge, as the design must enforce many severe constraints, among which energy dissipation is by far the most challenging one. Today, most of the WSN node platforms are based on low cost and low-power programmable micro controllers, even if it is acknowledged that their energy efficiency remains limited...
Recent developments in the fields of sensing, communication, and computing have driven the research efforts in context-aware devices, which can use context information to realize more intuitive interaction between human and machine. This paper developed a new conceptual design of intelligent motor controller that is able to access environment sensors and acquire related information so as to employ...
Sensor networks are often characterized by their large number of nodes that usually uses wireless communication, widely spread over sizeable geographical areas to monitor the environment. Considering their limited processing, memory and energy capacities, it becomes necessary for support mechanisms to ensure the rational use of their resources. It is in this context that we examine routing protocols,...
