How to provide fair service for V2I communications in VANETs?
PublikacjaIn this paper, we focus on fairness issues of Vehicle-to-Infrastructure (V2I) communications. In particular, we show that under a common technique of selection of RSUs by OBUs based on the received signal strength, a vast variability of a number of OBUs connected to RSUs can be observed leading to inefficient/unfair service provided by RSUs. To overcome this problem, we propose an algorithm for RSU selection called RSEL to obtain...

Bilateral multi-issue negotiation of execution contexts by proactive document agents
PublikacjaA proactive document can react to its actual environment by autonomously selecting and performing actions integrated into its body and interact with its user. When migrating over a network of execution devices it may encounter diverse execution contexts, each one set up according to temporal characteristics of a receiving device and preferences of its owner. A concept to augment proactive documents with negotiation capability is...

Postępy w rozwoju standardu IEEE 802.11 i jego zastosowań Część II: Nowe obszary zastosowań i nowe koncepcje pracy sieci WiFi
PublikacjaArtykuł stanowi kontynuację rozważań, podjętych w zeszycie nr 11 z 2016 r. PTiWT [1], na temat rozwoju standardu łEEE 802.11 , ukierunkowanego na zwiększanie szybkości przekazu i przekraczanie gigabitowej granicy przepływności łącza. Wskazano tam na modyfikacje i nowe mechanizmy implementowane w warstwie fizycznej i podwarstwie MAC standardów IEEE 802.11 n, IEEE 802.11 ac oraz IEEE 802.11 ad, mające istotny wpływ zarówno na wzrost...

Sub-regional service centres in reality and regional planning in Poland = Podregionalne osrodki obsługi w sferze realnej i planowaniu regionalnym w Polsce
PublikacjaSub-regional centres are defined as towns where the services of the sub-regional level are concentrated. In Poland these are such services that can be located in several towns in a voivodeship (region), but not in every capital of a poviat (county). The transformation of civilization has influenced changes in Christaller’s model of settlement network, but re-gularities are still valid. Models derived from Christaller's Central...
