This article comprehensively reviews the emerging concept of Internet Intelligent Things (IoIT), adopting an integrated perspective centred on areas embedded systems, edge computing, and machine learning. With rapid developments in these areas, new solutions are to address previously unsolved problems, demanding novel research development paradigms. In this sense, aims fulfil some important gaps, laying down foundations for cutting-edge works following ever-increasing trend based devices...
Mobile agents have been proposed as a means to address two important issues in the design of Wireless Sensor Networks (WSN): need for reprogramming network and decreasing energy expenditure. However, few mobile agent systems developed WSN so far. In this paper we describe MASPOT, system Sun SPOT, platform by Microsystems. MASPOT provides solution above extends range SPOT applications. To best our knowledge, is only Java-based that currently supports code migration. We present results an...
The global telecommunications environment is rapidly changing to a highly dynamic open environment, where multitude of competing and/or cooperating service providers offer steadily growing number increasingly powerful communication and information services. need for integration, ubiquitous access rapid provisioning requires an open, universal platform which supports both management applications. development such based on the concept distributed processing environments (DPEs) has been major...
For centuries, emergencies have been a recurring situation in cities. Natural or human-induced emergency situations can cause infrastructural damages cities, potentially resulting injuries, death, and economic losses. In this context, the use of Internet Things technologies support more efficient detection such as floods, landslides, fire, terrorism, being possible to alert people trigger mitigation actions on time. Therefore, work proposes an IoT platform for development sensors-based...
We present the concept of mobile groups as a basic mechanism for both reliable migration and coordination processes. Analogously to traditional group systems, also provide message delivery guarantees virtual synchrony. Furthermore, they make process mobility not only visible group, but consistently ordered with other actions (such crashes, joins, leaves, migrations). The approach represents novel support which can be used handle reliability distributed systems agent systems), at application...
In the last years mobile agents have gained much attention in industry and academic community. Many prototype systems some products providing agent capability been developed proposed for being used a set of application areas, such as electronic commerce, workflow systems, network management, among others. we also experienced an enormous development direction centric computing. Complex distributed environments emerge that enable support integration allow new forms automated cooperation. For...
Industrial environments are typically characterised by high levels of interference. Therefore, standards for industrial wireless sensor networks (WirelessHART, ISA 100.11a, and IEEE 802.15.4e) have defined a time division multichannel-based mode operation, in which slots channel pairs assigned to links representing communication between nodes. In 802.15.4e this operation is called Timed Slotted Channel Hopping (TSCH). paper we describe distributed algorithm define such an assignment given...
We describe a deterministic and randomized distributed algorithm for computing spanning tree over wireless network whose weight approximates the of Minimum Spanning Tree (MST). The is composed n static nodes embedded in 2-dimensional Euclidean space which communicate according to Signal-to-Interference- and-Noise Ratio (SINR) model. Under assumption that each node knows its position granularity g network, computes within O(D log g) rounds, where D diameter graph. When additionally know local...
Topology control is one of the main techniques that can be used to decrease energy spenditure in wireless sensor networks. Although it has been subject much research, less attention devoted study effects overhearing on topology control, i.e., cost implied by nodes hearing transmissions even if these were not intended them. In this paper we describe a distributed (localized) algorithm for Our approach differs from previous work mainly sense takes into consideration and might eliminate more...
A fundamental issue in the development of mobile agent systems is how to provide support for applications reliability. For some areas (such as electronic commerce or workflow) it that executions are fault tolerant and exhibit transactional semantics groups agents can coordinate their activities with use a reliable communication mechanism. This paper discusses reliability requirements introduces process suitable underlying concept fulfilling these requirements. Mobile an extension traditional...
The use domain of IEEE 802.11 networks has broadened to several types application, including those that require quality service and real-time guarantees. This trend in particular, motivated the formal methods, not only obtain a more precise knowledge protocol properties, but also specify validate them. In this context, contribution paper is twofold. First, we describe specification medium access control functions using UPPAAL, freeware model checker tool. described allowed us verify...
The coordination of cooperating Unmanned Aerial Vehicles (UAVs) has become an active area research. approaches to coordinate these so-called swarms generally include a solution class problems called Area Coverage as building block. coverage consist in obtaining information about certain interest (commonly polygon or polyhedron) using set UAVs, with decentralized and minimal human intervention. This problem models the requirements different types applications, such case emergencies disasters,...
