The advances on wireless mesh networks are shifting the communications paradigm, where users can benefit from their cooperation to exchange information and make use of the spectrum space, forming wireless neighbourhood communities where resources are shared and services are distributed. This paper presents a modular cross-layer community management architecture, which considers that communities are...
In this paper, we propose a method for cooperative surveys of the seafloor using multiple autonomous underwater vehicles (AUVs) where they detect areas of interest within the survey area in real-time based on a bathymetry map and then details are observed by them. The AUV firstly makes rough observations by mapping using an acoustic sensor and detects areas of interest based on a gradient descent...
While trying to get a service from the Base station it happens that many devices will find themselves competing to get the cellular service, which means each device will use the maximum power possible to win the competition, but if there is another solution that will allow the device to get what it wanted with minimum of energy, how the device will react to it? In other words, we know that the communication...
Social exclusion and costly punishment have been regarded as potential measures to solve the conundrum of cooperation recently. In real life, what is pretty widespread is the combined use of multiple strategies. Here, we propose two different strategy switching rules, namely, peer switching and pool switching, to investigate the effect of conditional switching between punishment and exclusion on cooperation...
Virtual assistants are promoted by the software industry as a radically new species of tools, but a clear definition of their specific way to interact with human users missing. The explicit goal of virtual assistants is to support human users by interacting with them in a fluent way, inspired by natural human communication and collaboration, which are now well understood by human sciences. This paper...
This paper proposes an architecture where each agent maintains a cooperative tendency table (CTT). In the process of learning, agents need not communicate with each other but observe partners' actions while taking actions. If one of the agents meets a bad situation, such as bumping onto obstacles after taking an action. In such a case, agents will receive a bad reward from the environment. Similarly,...
The article considers public safety as the main trends in political and economic international relations that ensure inter-state “balance of interests”. Given the characteristics of its structure, place and role in the governance of the States. The authors propose the balance of priorities in solving problems in the global scale of the space in terms of development of mutually beneficial political...
Models and main principles of cooperation between the social partners of the state, business and society in the process of educational projects realization are formulated. The ways of developing mechanisms and instruments of cooperation between social partners in the institutional environment of are offered.
In the near future, the global 5G ubiquitous network strategy that aims at deploying heterogeneous technologies for an internet access, involves also the rural RF deployment. While it is confirmed that 5G would meet stringent requirements in urban zones, rural areas still suffer from almost inexistent MBB (Mobile Broadband) coverage, especially in developing world. To cope with this issue, major insights...
We consider an energy harvesting (EH) relay-assisted, two hop, cooperative communication system. For it, we analytically characterize EH relay outage probability when the source device transmissions undergo small scale fading as well as large scale fading. In the analysis, we develop simple yet insightful upper bound for the EH relay outage probability. Furthermore, we investigate asymptotic outage...
In modern wireless networks autonomous agents may exhibit selfish or malicious behavior which can compromise the performance of the network. For this reason, Intrusion Detection Systems (IDS) have been proposed to monitor the agents' behavior, along with the deployment of Trust/reputation Management Systems (TMS) to enforce cooperation among the agents. IDS may not continuously monitor agents' behavior...
At present, the energy consumption of wireless communication network accounts for the vast majority of the operator's expenses. A cooperative energy saving mechanism is proposed in the framework of the self-organized network, based on the hybrid energy supplied, aiming at the energy consumption of cellular is too large and the utilization rate of green energy is low. According to the framework, the...
Vehicular Ad-hoc Networks may be used for multitude of services including those related to human safety, traffic management and providing comfort to the users as applicable to Intelligent Transportation Systems, Smart Communication Systems, Internet-of-Things etc. In most scenarios, vehicles are owned by different entities and therefore it may not be in the best of interest of VANETs nodes to forward...
Based on the circle model, three models of port pricing strategy are established by using game theory. The results show that the two ports will choose their best service quality when they both choose the single price strategy or the differential price strategy. The Nash equilibrium of the whole industry will develop towards higher service quality. Moreover, when ports implement differential pricing,...
There exists a patience when we treat everyone or anything around us in real life. Based on mutual punishment, in order to study the evolution of cooperation in spatial public goods game in the presence of patience in each individual, we introduce patience in this paper. And each cooperator has a patience and patience is changed after the execution of each game, when payoff of cooperator is always...
We study within this paper the effect of agents' management on the global performance of a multiagent system (MAS). Cooperative systems working under coalition formation strategies have been considered in this work. Our evaluation approach uses representation tools of the coalition formation process in addition to mathematical modeling techniques using utility functions. An empirical study has been...
In the 17th century, the beginning of the industrial era brought new ways of working, creating more effective ways to design and build products where cooperation played a very important role. In this context, we hypothesize that in the 21st century the problem of lack of invention in the design process of digital learning objects in general and of digital school textbooks in particular stems from...
The aim of this paper is to compare the learning effectiveness and learning motivation of digital game-based learning between the competitive and the cooperative mode. Forty-seven junior high school students were invited to participate in the learning experiment. The students were divided into two groups and played Fragrance Channel in two different modes. Pre-and post-tests were used to evaluate...
This paper presents the latest results of sea experiments conducted pertaining to a navigation method for wide-area surveys of the seafloor using multiple autonomous underwater vehicles (AUVs). Self-localization is essential for AUV navigation, and AUVs are typically supported by a long base line or super-short base line (SSBL). Here alternating landmark navigation (ALN) was proposed as an alternative...
Traffic congestion is a nuisance for urban centers. Traditional congestion management policies, like road pricing and road expansion, increase urban sprawl and inequity between road users. Recent developments in Information and Communication Technologies (ICT) enabled Advanced Travel Information Services (ATIS) that provide road users with real-time traffic information. Road users can benefit from...
