Multi-Resource Management for Multi-Tier Space Information Networks: A Cooperative Game

2019

With the drastic increase of space information network (SIN) traffic and the diversity of network traffic types, the optimal allocation of the scarce network resources is of great significance for optimizing the SIN system capability. In this paper, we propose a multi-resource management method for multi-tier SIN using the cooperative Nash bargaining solution. Since the original problem is a non-convex problem, we firstly make logarithmic transition, and then find a tightest lower bound function to convert the initial problem into a convex one. In order to carry out the optimal bandwidth and power allocation in SIN, we construct a joint bandwidth and power allocation (JBPA) algorithm. Simul…

Performance Analysis of Cooperative V2V and V2I Communications Under Correlated Fading

2019

Cooperative vehicular networks will play a vital role in the coming years to implement various intelligent transportation-related applications. Both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will be needed to reliably disseminate information in a vehicular network. In this regard, a roadside unit (RSU) equipped with multiple antennas can improve the network capacity. While the traditional approaches assume antennas to experience independent fading, we consider a more practical uplink scenario where antennas at the RSU experience correlated fading. In particular, we evaluate the packet error probability for two renowned antenna correlation models, i.e., cons…

Play and liberty : A brief incursion into some ideological currents in the history of systems‐oriented family therapy

2022

We reflect on family therapy and its history from two points of view, as an entity that becomes understood with the help of a twofold concept of a game, and a twofold concept of liberty. Systemic family therapy has always been comprehended with the help of game theory. Its development becomes more properly understood if we keep in mind that game itself is a dualistic concept entailing both a cultural and a logico-mathematical interpretation of a game. We show how cultural ethos has molded the ways how game metaphor have been implemented to systemic thinking. In the same manner we show how Isaiah Berlin's idea of two incompatible concepts of liberty helps to contextualize family therapy in a…

Uniform measure density condition and game regularity for tug-of-war games

2018

We show that a uniform measure density condition implies game regularity for all 2 < p < ∞ in a stochastic game called “tug-of-war with noise”. The proof utilizes suitable choices of strategies combined with estimates for the associated stopping times and density estimates for the sum of independent and identically distributed random vectors. peerReviewed

Incentive Mechanism for Edge-Computing-Based Blockchain

2020

Blockchain has been gradually applied to different Internet of Things (IoT) platforms. As the efficiency of the blockchain mainly depends on the network computing capability, how to make sure the acquisition of the computational resources and participation of the devices would be the driving force. In this work, we focus on investigating incentive mechanism for rational miners to purchase the computational resources. A edge computing-based blockchain network is considered, where the edge service provider (ESP) can provide computational resources for the miners. Accordingly, we formulate a two-stage Stackelberg game between the miners and ESP. The aim is to investigate Stackelberg equilibriu…

Incentive Mechanism for Edge Computing-Based Blockchain: A Sequential Game Approach

2022

The development of the blockchain framework is able to provide feasible solutions for a wide range of Industrial Internet of Things (IIoT) applications. While the IIoT devices are usually resource-limited, how to make sure the acquisition of computational resources and participation of the devices will be the driving force to realize blockchain. In this work, an edge computing-based blockchain framework is considered, where multiple edge service providers (ESPs) can provide computational resources to the IIoT devices. We focus on investigating the trading between the devices and ESPs, where ESPs are the sellers and devices are the buyers. A sequential game is formulated and by exploring the…

Ei-yhteistoiminnallisten pelien sovelluksia langattomissa verkoissa

2011

Laitinen, Jouni Ei-yhteistoiminnallisten pelien sovelluksia langattomissa verkoissa Jyväskylä: Jyväskylän yliopisto, 2011, 36 s. Tietojenkäsittelytiede, kandidaatin tutkielma Ohjaaja: Hirvonen, Pertti Peliteorian suosio on viime vuosina kasvanut uusien sovellusten myös. Näihin sovelluksiin kuuluu myös langattomat tietoverkot ja niissä tapahtuvat kanssakäynnit. Peliteorian avulla näitä tapahtumia voidaan analysoida tarkemmin ja niiden tehokkuutta nostaa. Tässä kirjallisuuteen pohjautuvassa kandidaatin tutkielmassa esitellään ensin peliteorian perusteita, joita sitten sovelletaan langattomien tietoverkkojen eri ongelmiin. Näitä ongelmia ovat: lähetystehon määrittäminen, taajuuden vaihtaminen …
