nnotatsiya. Opportunistik tarmoqlar – uzluksiz
ulanish, yuqori dinamika va cheklangan infratuzilma
kabi qiyin sharoyitlarda ishlaydigan tarmoqlarning
noyob sinfidir. Ushbu tarmoqlar turli ssenariylarda,
jumladan, favqulotda holatlar yuz berganda, chekka hududlar
va avtomobil aloqalarida qo ‘llanilishi tufayli katta e’tibor
qozondi. Ushbu tezisda opportunistik tarmoqlarning
dolzarbligi, arxitekturasi, mobillik modellari va marshrutlash
protokollari o‘rganiladi.
Kalit so‘zlar: DTN, MANET, Oppnet, marshrutizatsiya,

OPPORTUNISTIC
NETWORKS:
ARCHITECTURE,
MOBILITY MODELS
AND ROUTING
PROTOCOLS
A
bstract: Opportunistic networks are a unique class of
networks that operate under challenging conditions
such as continuous connectivity, high dynamics,
and limited infrastructure. These networks have gained a lot
of attention due to their use in various scenarios, including
emergencies, remote areas and vehicular communications.
This thesis examines the relevance, architecture, mobility
models and routing protocols of opportunistic networks.
Keywords: DTN, MANET, Oppnet, routing, mobility
model.

СПЛАЙНОВ
А
ннотация: в статье обсуждается, как использовать
сплайн-функции для геологических сигналов,
и предлагаются алгоритмы параметризации
сплайнов. Для этого возьмем в качестве примера
трехточечный вынос, работающий режиме реального
времени. Уникальность этих формул заключается в
независимости значения оцениваемого сплайна на этом
участке.
Ключевые слова: сплайн, базисный сплайн,
аппроксимация, b -коэффициенты, «точечные» формулы,
приближения, полиномы Ньютона, алгоритм.

ALGORITHMS
FOR RECOVERING
GEOLOGICAL
SIGNALS USING
SPLINES
A
bstract: The article discusses how to use spline
functions for geological signals and proposes spline
parameterization algorithms. For this purpose, we
take a three-point offset operating in real time as an example.
The uniqueness of these formulas lies in the independence of
the estimated spline value in this section.
Keywords: spline, basis spline, approximation,
b-coefficients, “point” formulas, approximations, Newton
polynomials, algorithm.
