The IEEE 1451 smart transducer interface standard aims at establishing a common interface to promote interoperability among the myriad of transducers currently in the market. Nonetheless, the acceptance of the standard in the realm of Wireless Sensor Networks (WSN) seems to be constrained by apparently incompatible operational semantics: while ordinary transducers deployed in control networks usually...
It is a mistake to assume that each embedded object in the Internet of Things will implement a TCP/IP stack similar to those present in contemporary operating systems. Typical requirements of ordinary things, such as low power consumption, small size, and low cost, demand innovative solutions. In this article, we describe the design, implementation, and evaluation of a trustful infrastructure for...
Receiver-based MAC (RB-MAC) is a preamble-sampling MAC protocol for WSNs in which a receiver node is dynamically elected, among potential neighbors of the sender node, based on current channel conditions. In this paper, we evaluate the performance of RB-MAC and compare it with a sender-based preamble-sampling MAC protocol by using analytical methods, and implementation in real sensor nodes. We have...
This article describes the design, implementation and evaluation of a trustful infrastructure for the Internet of Things (IoT) based on EPOS Mote. The infrastructure was built around EPOS' second generation of motes, which features an ARM processor and an IEEE 802.15.4 radio transceiver. It is presented to end users through a trustful communication protocol stack compatible with TCP/IP. Trustfulness...
C-MAC is a highly configurable MAC protocol realized as an architecture of medium access control strategies that can be combined to produce application-specific protocols. By selecting the proper strategies and configuring their parameters, programmers can instantiate MAC protocols that closely match their applications' requirements. C-MAC relies on static metaprogramming techniques to achieve high...
