Image Compression And Retrieval For Mobile Visual Search, Yi Cao, Christian Ritz, Raad Raad
Image Compression And Retrieval For Mobile Visual Search, Yi Cao, Christian Ritz, Raad Raad
Dr Raad Raad
Mobile Visual Search (MVS) is an emerging area of research given the explosion of smart and computationally powerful mobile devices. Typically, MVS involves the computation of local image features which are then used within a matching process. Such applications pose certain unique challenges due to computation, power and bandwidth constraints of the mobile device. This paper examines the trade-off between two general frameworks for implementing MVS: 1. sending compressed images and performing feature extraction and matching on a server; and 2. performing feature extraction on the mobile device and sending these to a server for matching. A number of local …

Session Based Differentiated Quality Of Service Admission Control For Web Servers, Yaya Wei, Chuang Lin, Fengyuan Ren, Eryk Dutkeiwicz, Raad Raad
Dr Raad Raad
Recent advance-session based admission control (SBAC) has resulted in protecting the server from entering a regime in which latencies are excessive or session throughput collapses due to dropped requests and aborted sessions. The goal of this work is to introduce differentiated QoS to SBAC. We propose a two-threshold SBAC scheme (QSBAC). It can provide high throughput for preferred clients especially in overload situation. Furthermore, to adapt to varying traffic loads, a dynamic QSBAC (DQSBAC) scheme is also proposed. The experimental results show that comparing with SBAC scheme, both QSBAC scheme and DQSBAC scheme can sustain higher session throughput for preferred …

Securing Dsr Against Wormhole Attacks In Multirate Ad Hoc Networks, Shams Qazi, Raad Raad, Yi Mu, Willy Susilo
Dr Raad Raad
A wormhole attack is one of the hardest problems to detect whereas it can be easily implanted in any type of wireless ad hoc network. A wormhole attack can easily be launched by the attacker without having knowledge of the network or compromising any legitimate nodes. Most existing solutions either require special hardware devices or make strong assumptions in order to detect wormhole attacks which limit the usability of these solutions. In this paper, we present a security enhancement to dynamic source routing (DSR) protocol against wormhole attacks for ad hoc networks which relies on calculation of round trip time …
