  1. CPA: A Cluster-Based Packet Acknowledgement Approach in WSNs

  2. In wireless sensor network, repairing packet loss lead to increasing of the network load and substantial energy consumption. In order to reduce the network load, most of transport protocols employ a Cumulative Acknowledgment (CACK) policy for receive

  1. Spectrum consecutiveness based routing and spectrum allocation in flexible bandwidth networks

  2. In flexible bandwidth optical networks, the dynamic lightpath setup and teardown inevitably lead to spectrum fragmentation which blocks the new connections. In order to effectively allocate the spectrum along a better route, a notion of available spe

  1. A Novel Uplink Data Transmission Scheme For Small Packets In Massive MIMO System

  2. Abstract—Intelligent terminals often produce a large num- ber of data packets of small lengths. For these packets, it is inefficient to follow the conventional medium access control (MAC) protocols because they lead to poor utilization of se

  1. A Variational Model of Image Restoration Based on First and Second Order Derivatives and Its Split Bregman Algorithm

  2. The variational models of diffusion using first order derivatives can efficiently remove the noises of images with edge preserving property, but they usually lead to staircase effects. This problem can be overcome via mixed regularizers using first o

  1. BFO: Batch-File Operations on Massive Files for Consistent Performance Improvement

  2. Existing local file systems, designed to support a typical single-file access pattern only, can lead to poor performance when accessing a batch of files, especially small files. This singlefile pattern essentially serializes accesses to batched files
