Co to jest czas?
PublicationŚwięty Augustyn wypowiedział kiedyś takie słowa: "Czymże jest czas? Jeśli nikt mnie o to nie pyta, wiem. Jeśli pytającemu usiłuję wytłumaczyć, nie wiem." Nie ma wątpliwości, że czas jest czymś ważnym,a nawet bardzo ważnym - bez niego nic by się nie działo. Czy czas nie jest tym dobrem, którego nam brakuje najczęściej? Wielu filozofów widzi w czasie jedną z podstaw wszelkich sądów matematycznych.Strategiczną rolę czasu jeszcze bardziej...

A Centralized Reputation System for MANETs Based on Observed Path Performance
PublicationA reputation system for MANETs is described that attempts to deduce nodal trustworthiness (forwarding behaviour) from observed end-to-end path performance. The trustworthiness deduction algorithm produces interval estimates and works well if node misbehaviour is not selec-tive with respect to traversing paths. Nodal reputation levels are next calculated in the spirit of generous tit-for-tat so as to best reflect momentary nodal...
