Optimizing TCP (Transport Layer) for mobility has been researched extensively. We present a brief summary of existing results which indicates that most schemes require intermediaries (such as base stations) to monitor the TCP traffic and actively participate in flow control in order to enhance performance. Although these methods simulate end-to-end semantics, they do not comprise true end-to-en...

This paper presents the evaluation performance of a hybrid satellite constellation network which provides internet access based Transport Control Protocol (TCP). The evaluated satellite network uses the constellation topology operating on Low Earth Orbit (LEO). The COMMStellationTM satellite system implemented using network simulator 2 (NS-2). In this paper, we modified a congestion window cont...

Data Cleaning refers to the process of detecting and fixing errors in the data. Human involvement is instrumental at several stages of this process, e.g., to identify and repair errors, to validate computed repairs, etc. There is currently a plethora of data cleaning algorithms addressing a wide range of data errors (e.g., detecting duplicates, violations of integrity constraints, missing value...

Real-time communication is crucial for wireless sensor networks (WSNs) to accomplish collaborative event sensing tasks with specific timing constraints. In this work, a servicedifferentiated real-time communication scheme (SDRCS) is developed to provide soft real-time guarantees for event-based traffic in WSNs. SDRCS features a cross-layer packet forwarding design to integrate the real-time rou...

More and more handsets manufactured today are being equipped with WLAN modules, allowing users to access VoIP service whenever they are within the coverage of WLAN service area. One of the greatest challenges for such dual-mode (say GSM and WiFi) handsets to support ubiquitous communication is the ability to maintain session continuity so a phone call established through one mode can be transfe...

3D object reconstruction from a single image is a highly under-determined problem, requiring strong prior knowledge of plausible 3D shapes. This introduces challenges for learning-based approaches, as 3D object annotations are scarce in real images. Previous work chose to train on synthetic data with ground truth 3D information, but suffered from domain adaptation when tested on real data. In t...

Large growth in e-commerce has culiminated in technology boom to enable companies to better serve their consumers. The front-end of the e-commerce business is to better reach the consumer which means to better serve the information on the Web. An end-to-end solution that provides such capabilities includes technology to enable personalization of information, to serve the personalized informatio...

We propose a new method that uses deep learning techniques to solve the inverse problems. The inverse problem is cast in the form of learning an end-to-end mapping from observed data to the ground-truth. Inspired by the splitting strategy widely used in regularized iterative algorithm to tackle inverse problems, the mapping is decomposed into two networks, with one handling the inversion of the...

Link-layer retransmission is a feature of IEEE 802.11 protocol that aims to increase the reliability of data communications. However, when successive retransmissions fail, retransmissions add to the traffic congestion, raise the collision probability, and increase the end-to-end delay. Using our 4-hop wireless mesh network testbed, we evaluate the impact of link-layer retransmissions on the per...

Time matters. In a networked world, we would like mobile devices to provide a crisp user experience and applications to instantaneously return results. Unfortunately, application performance does not depend solely on processing time, but also on a number of different components that are commonly counted in the overall system latency. Latency is more than just a nuisance to the user, poorly acco...
