Timed-token networks, such as FDDI, support both synchronous real-time traffic and non real-time traffic (asynchronous messages). The medium access scheme of FDDI guarantees up to one half of the total network band-width for synchronous communication. Further enhancements , such as FDDI-M, improve the bandwidth dedicated to real-time messages. However, the(More)
—Monitoring teams of mobile nodes is becoming crucial in a growing number of activities. When it is not possible to use fix references or external measurements, a practicable solution is to derive relative positions from local communication. In this work, we propose an anchor-free Received Signal Strength Indicator (RSSI) method aimed at small multi-robot(More)
—The design of wireless embedded systems for real-time applications requires a careful management of timing and energy requirements. This paper describes a wireless communication protocol that can guarantee both message deadlines and system lifetime by properly allocating the network bandwidth to each node. The protocol allows multi-hop wireless(More)
—Recently, researchers and engineers began considering the use of WSN in time-sensitive applications. For effective real-time communications, it is important to solve the problem of contention to the communication medium providing an efficient bandwidth allocation mechanism. In this paper we tackle with the problem of performing timely detection of events(More)
Token passing channel access mechanisms are used in several communication networks. An important class of token passing approaches are the so-called timed token protocols , which are able to manage both real-time traffic and non real-time traffic. Recently, a new token passing protocol , called Budget Sharing Token protocol (BuST), was proposed to improve(More)
A crucial objective in battery operated embedded systems is to work under the minimal power consumption that provides a desired level of performance. Dynamic Voltage Scaling (DVS) and Dynamic. Power Management (DPM) are typical techniques used on processors and devices to reduce the power consumption through speed variations and power switching,(More)
In embedded systems operated by battery and interacting with the environment, a fundamental issue is the enforcement of real-time and energy constraints to guarantee a desired lifetime with a given performance. A lot of research has focused on energy management at the communication level; however, not many authors considered both real-time and energy(More)
—Low energy consumption is one of the primary issues that have to be addressed in body area networks to prevent frequent battery recharges in the nodes. Such networks are being increasingly used to acquire sensory data that need to be processed in real-time. The Bluetooth Low Energy (BLE) protocol is an attractive solution for implementing personal area(More)
