A new method for improving security in MANETs AODV Protocol [PDF]

open access: yesManagement Science Letters, 2012
In mobile ad hoc network (MANET), secure communication is more challenging task due to its fundamental characteristics like having less infrastructure, wireless link, distributed cooperation, dynamic topology, lack of association, resource constrained ...

Employ DBSCAN and Neighbor Voting to Screen Selective Forwarding Attack Under Variable Environment in Event-Driven Wireless Sensor Networks

open access: yesIEEE Access, 2021
In the event-driven wireless sensor networks (EWSNs), the event of interests occurs irregularly and at random in the network. Then, sensor nodes near the event sense the event and send out data packets of the event. Next, router nodes (RNs) forward those

A smart packet type identification scheme for selective discard of video packets

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
In recent years, due to the growth of social networks and development of video sharing platforms, transmission of video content has increased dramatically. This huge amount of data imposes a heavy load on the limited bandwidth of the networks.

A QoS Scheme for a Congestion Core Network Based on Dissimilar QoS Structures in Smart-Phone Environments

open access: yesSensors, 2010
This study suggests an approach to effective transmission of multimedia content in a rapidly changing Internet environment including smart-phones. Guaranteeing QoS in networks is currently an important research topic. When transmitting Assured Forwarding

Queuing system GI/M/1/N with randomly dropping packets mechanism

open access: yesTongxin xuebao, 2006
For the original GI/M/1/N queuing system was not suitable to model the queue management mechanism,a queuing system GI/M/1/N with randomly dropping packets mechanism was discussed by means of thinning of recurrent flows.In addition,the packet loss rate ...

Item-dropping to improve in-sample Cronbach's alpha can harm true reliability: A Monte Carlo simulation

open access: yes
Cronbach's alpha is the most commonly reported metric of reliability in psychological measurement, and statistical software encourages a common post hoc revision: dropping the item whose removal most improves in-sample alpha.

Swift HARQ Based on Machine Learning for Latency Minimization in URLLC

open access: yesIEEE Access, 2023
Ultra-reliable low-latency communication (URLLC) has been introduced in the 5th Generation (5G) radios for mission-critical applications that demand strict reliability and latency traffic to guarantee the rapid delivery of short packets (up to 1 ms) with

Queueing systems with different types of renovation mechanism and thresholds as the mathematical models of active queue management mechanism

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2020
This article is devoted to some aspects of using the renovation mechanism (different types of renovation are considered, definitions and brief overview are also given) with one or several thresholds as the mathematical models of active queue management ...

On loss probabilities in presence of redundant packets with random drop [PDF]

open access: yesPerformance Evaluation, 2002
We study the loss probabilities of messages in an M/M/1/K queueing system where in addition to losses due to buffer overflow there are random losses on the incoming and outgoing links. We focus on the influence of adding redundant packets to the messages. We obtain analytical results that allow us to investigate when does adding redundancy decrease the
