Maximum-and-Concatenation Networks [article]

Xingyu Xie, Hao Kong, Jianlong Wu, Wayne Zhang, Guangcan Liu, Zhouchen Lin
2020 arXiv   pre-print
In this work, we propose a novel architecture called Maximum-and-Concatenation Networks (MCN) to try eliminating bad local minima and improving generalization ability as well.  ...  While successful in many fields, deep neural networks (DNNs) still suffer from some open problems such as bad local minima and unsatisfactory generalization performance.  ...  Maximum-and-Concatenation Networks The design of our MCN-a linearity and maximum concatenation network-is inspired by the following observations.  ...

IPAC: IP-based Adaptive Packet Concatenation for Multihop Wireless Networks

Ramya Raghavendra, Amit P. Jardosh, Elizabeth M. Belding, Haitao Zheng
2006 2006 Fortieth Asilomar Conference on Signals, Systems and Computers  
In this paper, our goal is to reduce contention through concatenation of several small packets into a single large packet, and subsequently transmit this large packet.  ...  As a result of contention overhead, end-to-end delay and energy dissipation increase and the medium utilization decreases.  ...  ACKNOWLEDGMENTS This work was supported in part by NSF Career Award CNS-0347886 and by NSF NeTS Award CNS-0435527.  ...

Packet concatenation at the IP level for performance enhancement in wireless local area networks

Dzmitry Kliazovich, Fabrizio Granelli
2007 Wireless networks  
The performance of the proposed algorithm is evaluated through both simulations and an experimental WLAN testbed environment covering the single-hop and the widespread infrastructure network scenarios.  ...  Wireless local area networks experience performance degradation in presence of small packets. The main reason for that is the large overhead added at the physical and link layers.  ...  Concatenation and fragmentation concepts are both designed to adjust the outgoing traffic to network data units of a given size.  ...

Loss Resilient Strategy in Body Sensor Networks

Nick Read, Ming Li, Yu Cao, Shih-Hsi Liu, Todd Wilson, Balakrishnan Prabhakaran
2011 Proceedings of the 6th International ICST Conference on Body Area Networks  
In this paper, we propose a loss resilient strategy where prioritized scheduling and packet concatenation schemes are integrated for high network capacity and acceptable data reliability.  ...  Body sensor networks have gained continuous popularity in applications such as monitoring, sports training, and interactive gaming.  ...  It may be desirable to perform some fine-tuning with the MAC message structure and design the concatenation at the MAC level for maximum throughput improvement.  ...

Defending Synchrophasor Data Networks Against Traffic Analysis Attacks

Biplab Sikdar, Joe H. Chow
2011 IEEE Transactions on Smart Grid  
Considering the periodic nature of synchrophasor data, we propose defense mechanisms based on packet concatenation and random packet drops as a countermeasure against attacks that may use the timing as  ...  well as data volume information to compromise the network.  ...  Given the sampling rate of the synchrophasor measurement units and compensating for the network latency, the maximum number of packets that may be concatenated can be easily obtained.  ...

Dynamic Capacity Allocation in OTN Networks

Maria Catarina Taful, João Pires
2015 Communications and Network  
Virtual Concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS) are two techniques that when properly combined can be used to provide improved dynamism in OTN networks.  ...  This feature has the potential to reduce operational costs and at the same time to optimize networks resources.  ...  For the UBN network the maximum distance between network nodes goes up to 7,200 km leading to a maximum propagation delay of about 144 ms.  ...

Using Feature Fusion and Parameter Optimization of Dual-input Convolutional Neural Network for Face Gender Recognition

Cheng-Jian Lin, Cheng-Hsien Lin, Shiou-Yun Jeng
2020 Applied Sciences  
In recent years, convolutional neural networks (CNNs) have been successfully used in image recognition and image classification. General CNNs only use a single image as feature extraction.  ...  The experimental results show that in the dual-input CNN experiment, average accuracy rates of 99.98% and 99.11% on the CIA and MORPH data sets are achieved, respectively, which is superior to the traditional  ...  The weighting fusion result is obtained more effectively than the concatenation method, sum method, product method and maximum method.  ...

Efficiency Issues in MPLS Transport for the UMTS Access Network [chapter]

Enrique Vázquez, Manuel Álvarez-Campana, Ana B. García
2004 Lecture Notes in Computer Science  
However, the efficient transport of short voice and data packets in the UMTS access network requires multiplexing and segmentation functions not provided by MPLS.  ...  Multiprotocol Label Switching (MPLS) offers a simple and flexible transport solution for multiservice networks. Therefore, many UMTS operators are currently considering the use of a MPLS backbone.  ...  They are concatenated up to Timer_CU expiration or up to a given maximum length Lmax (e.g. set to comply with a maximum transmission time in the Node B -Edge Router link), and transmitted over an LSP preceded  ...
