Improving Fairness and Convergence Efficiency of TCP Traffic in Multi-hop Wireless Networks
Wireless Personal Communications - Tập 121 - Trang 459-485 - 2021
Last-mile telecommunication networks witnessed phenomenal growth in using
multi-hop wireless technologies to improve capacity and radio coverage for a
longer extent. The penetration of wireless internet in last-mile multi-hop
networks has significantly altered our routine lifestyle. Most internet
applications heavily rely on transmission control protocol (TCP) to reliably
deliver data packets betw...
In Search of a Location-Centric Rain Attenuation Model
Wireless Personal Communications - Tập 124 - Trang 315-332 - 2022
In search of an accurate location-centric rain-induced attenuation model, in
this paper, the authors have investigated the measured attenuation and rainfall
intensities at a few locations in India, namely Amritsar, Kolkata, Kondapalli,
and New Delhi. The proposed model predicts rain-induced attenuation as a
function of a few location-centric parameters, like the height from the mean sea
level, the...
Capacity of wireless dynamic TDMA and media access control for packetized voice/data integration
Wireless Personal Communications - Tập 1 - Trang 313-319 - 1994
We obtain the capacity of wireless dynamic TDMA for packetized speech and
investigate its stability characteristics depending upon the ratio between
request slots and message slots. We analyze this system based on an imbedded
Markov chain approximation and validate its performance by simulation. We also
propose a new media access control for voice/data integration and investigate
its performance b...
Performance Analysis of Smart Relaying with Equal Gain Combining
Wireless Personal Communications - Tập 65 - Trang 273-292 - 2011
Relaying communications has been proposed as a way to provide spatial diversity.
In general, one is interested in a relaying system that can achieve the maximal
diversity order with a low system complexity. One enabling technique is equal
gain combining (EGC) and its application in relaying systems is the main focus
of this paper. In particular, the techniques of EGC and smart relaying are
combine...
Cảm biến phổ dựa trên giá trị tuyệt đối cumulating với tiếng ồn Laplace trong mạng radio nhận thức Dịch bởi AI
Wireless Personal Communications - Tập 83 - Trang 1387-1404 - 2015
Cảm biến phổ trong sự hiện diện của tiếng ồn không Gaussian là một vấn đề thách
thức đối với các mạng radio nhận thức. Tuy nhiên, có rất ít bộ phát hiện có thể
hoạt động tốt trong trường hợp này. Dựa trên điều này, chúng tôi đề xuất một
thuật toán cảm biến phổ thông qua việc tích lũy giá trị tuyệt đối (AVC) với
tiếng ồn Laplace. Thuật toán AVC tận dụng tối đa các thuộc tính ngẫu nhiên của
tiếng ồn...

Resource Allocation in Downlink OFDM Wireless Systems with User Rate Allowed Regions
Wireless Personal Communications - - 2014
In this paper, a novel adaptive resource allocation in downlink orthogonal
frequency division multiplexing wireless system is investigated. Different from
the conventional algorithms, user rate allowed regions are considered. That is,
not only the user minimum rate requirements are to be satisfied, but also the
maximum rate limitations are introduced to make resource allocation more
reasonable. Gi...
Diversity Combining and Equalization with TCM for Wireless Communications
Wireless Personal Communications - Tập 20 - Trang 41-60 - 2002
This paper presents an equalization structure in which antennadiversity,
adaptive decision feedback equalization (DFE), interleavingand trellis-coded
modulation (TCM) can be effectively combined to combatboth ISI and cochannel
interference in cellular mobile radioenvironments. The feedback filter of the
DFE can use either tentative orfinal decision symbols of the TCM Viterbi
decoding to cancel tai...
Congestion Control Framework for Ad-Hoc Wireless Networks
Wireless Personal Communications - Tập 52 - Trang 753-775 - 2009
During the last few years, bandwidth and traffic control have immerged as issues
of great importance in ad-hoc wireless networks, requiring sophisticated
managing techniques. Moreover, due to the increasing variety of applications and
consequently respective need for bandwidth control, such issues are expected to
become even more critical in the near future. Main characteristics of MANETs
such as ...
Tapered Antenna Array with Non-identical Triangular MSA Elements for FSLL Reduction
Wireless Personal Communications - Tập 106 - Trang 1339-1352 - 2019
Reduced interference from nearby communication systems is an essential need in
all generations of wireless communication systems. In this paper, interference
is reduced by reducing the first side lobe level (FSLL) by using the concept of
tapering realized with non-identical triangular elements. Resonance frequency of
an Equilateral triangular microstrip antenna depends on its patch height. This
pr...
