Macbeth / Macbett : répétition tragique et répétition comique de Shakespeare à Ionesco

Réécriture du Macbeth de Shakespeare, où les répétitions sont au service de la manifestation du destin, le Macbett de Ionesco fait un usage immodéré de la répétition, qui produit des effets à la fois comiques et inquiétants et contamine tous les paramètres de l’action dramatique. Au redoublement des personnages, qui perdent toute individualité, répondent les répétitions structurelles, manifestant l’éternel retour des tyrannies dans l’Histoire, et les répétitions de formules stéréotypées, révélant la vacuité du discours politique. Le comique dérisoire et pessimiste de Macbett manifeste ainsi l’ambivalence de la répétition, qui exalte surtout la puissance du théâtre dont elle apparaît comme une ficelle des plus efficaces.Rewriting Shakespeare’s Macbeth, in which repetitions are used to express fate, Ionesco makes an immoderate use of repetition in his Macbett; at the same time he creates comic and disturbing effects and modifies all the parameters of the drama. The redundancy of characters, who loose their individuality, is echoed by the repetition of structures which express the endless return of tyranny in History, as well as by the repetition of stereotypes which reveal the vacuity of political discourse. The derisive and pessimistic comic tonality of Macbett thus brings out the ambivalence of repetition, which above all exalts the power of theatre and proves itself to be one of its most efficient tricks

ADTH: Bounded Nodal Delay for Better Performance in Wireless Ad-hoc Networks

© 2018 Delay is an unavoidable factor that occurs within networks and may be exacerbated by the nature of wireless ad-hoc networks. Maintaining a manageable level of delay may be required to provide satisfactory performance for each of the nodes that form the network. The variability of IoT devices, topologies and network conditions demand that a standalone and scalable scheme be used. ADTH is first shown to accomplish this through simulations with the NS-2 network simulator. The scheme was then used with testbed implementation with Gumstix devices and real-time traffic provided by an STC Traffic Generator. These demonstrated its effectiveness in managing flows of delay sensitive traffic, in addition to delivering superior bandwidth utilisation than standard policies

Efficient Congestion Minimisation by Successive Load Shifting in Multilayer Wireless Networks

Congestion in wireless networks is one of the major causes of system inefficiency, and with router load being the main contributor to overall network traffic flow, congestion is very dependent on the level of router load and how it can be effectively managed. This paper presents a novel low-complexity Successive Load Shifting (SLS) technique for intelligently shifting router load between network routers by predicting the probability of congestion occurrences in the network and exploiting the topology to reassign load to minimise congestion. Crucially, SLS does not compromise the data rate in avoiding congestion and is able to be seamlessly embedded into existing protocols with only a small increase incurred in system overheads. The performance of SLS has been extensively tested and critically evaluated using the widely adopted TCP and UDP protocols, with results confirming both significant throughput gains and superior packet loss performance

Robotic Wireless Sensor Networks

In this chapter, we present a literature survey of an emerging, cutting-edge, and multi-disciplinary field of research at the intersection of Robotics and Wireless Sensor Networks (WSN) which we refer to as Robotic Wireless Sensor Networks (RWSN). We define a RWSN as an autonomous networked multi-robot system that aims to achieve certain sensing goals while meeting and maintaining certain communication performance requirements, through cooperative control, learning and adaptation. While both of the component areas, i.e., Robotics and WSN, are very well-known and well-explored, there exist a whole set of new opportunities and research directions at the intersection of these two fields which are relatively or even completely unexplored. One such example would be the use of a set of robotic routers to set up a temporary communication path between a sender and a receiver that uses the controlled mobility to the advantage of packet routing. We find that there exist only a limited number of articles to be directly categorized as RWSN related works whereas there exist a range of articles in the robotics and the WSN literature that are also relevant to this new field of research. To connect the dots, we first identify the core problems and research trends related to RWSN such as connectivity, localization, routing, and robust flow of information. Next, we classify the existing research on RWSN as well as the relevant state-of-the-arts from robotics and WSN community according to the problems and trends identified in the first step. Lastly, we analyze what is missing in the existing literature, and identify topics that require more research attention in the future
