Journal of Telecommunications and Information Technology
2011 nr 1 69-77
EN In this paper a modification of the widely used Kademlia peer-to-peer system to tactical networks is proposed. We first take a look at the available systems today to cover the range of possibilities peer-to-peer systems offer. We identify candidates for use in military networks. Then we compare two [...]

2019 nr 1 58--66
EN This paper proposes a novel peer-to-peer communication framework to implement geographical location oriented networks, called G-LocON. Location-based services have been gaining in popularity, as proven by ridesharing and mobile games. Although these services have to construct geolocation oriented ne[...]

EN Spatial databases present challenges to data management not found in typical RDBMS. Among these is the desire of users for highly distributed access to data. A new peer to peer database model is being developed that supports high distribution and concurrency of information access. Some aspects of th[...]

EN Most geolocation applications for mobile devices assume a constant connection with the network and high computational power nodes. However, with ever-developing devices it now becomes possible to establish peer-to-peer networks in case when the network can be unreachable due to special circumstances[...]

2013 Vol. 38, No. 2 111--122
EN Transactional memory is a rather novel approach to concurrency control in parallel computing, that has just recently found its way into distributed systems research. However, the research concentrates mainly on single processor solutions or cluster environment. In this paper we argue, that peer-to-p[...]
Ekonomia i Zarządzanie
EN Information and communication technologies enable the emergence of a new phenomenon called the “sharing economy”. An increasing number of articles in the media as well as debates about the positive and negative aspects of the sharing economy show a growing interest in the subject. The paper aims to [...]

EN This article reports on the results of our measurement study of the Kad network. Although several fully decentralized peer-to-peer systems have been proposed in the literature, most existing systems still employ a centralized architecture. The Kad network is a notable exception. Since the demise of [...]
Journal of Automation Mobile Robotics and Intelligent Systems
EN The most prevalent P2P application today is file sha ring, both among scientific users and the general public. Afundamental process in file sharing systems is the search mechanism. The unstructured nature of real-world largescale complex systems poses a challenge to the search me thods, because glob[...]

EN The development of high speed mobile networks and the widespread use of smartphones have enabled users to easily obtain large data volumes via the Internet. This causes a heavy consumption of network resources, a burden on the available bandwidth. To solve such problems, a data offloading method with [...]
Computational Methods in Science and Technology
EN We propose a grid programming approach using the ProActive middleware. The proposed strategy addresses several grid concerns, which we have classified into three categories. I. Grid Infrastructure which handles the resource acquisition and creation using deployment descriptors and Peer-to-Peer. II. [...]
Journal of Applied Computer Science
EN The paper describes aspects of integrating relational resources in an object-oriented data intensive grid with extensive description of a grid architecture. The presented solution is generic and allows utilizing native query optimizers of a relational resource (indices, fast joins, etc.), which can [...]
