Vertical Handover Efficient Transport for Mobile IPTV (WiMoA 2011 and ICCSEA 2011) Part 2

Evaluation Frame-by-frame results in Fig. 3 isolate the effect on video quality (PSNR) of vertical handovers from IEEE 802.16e to 802.11b and vice versa. When the mobile SS loses connection to the IEEE 802.16e BS it is at 0.93 km distance from the BS, whereas when it connects to the IEEE 802.11b AP it is […]

Job Scheduling for Dynamic Data Replication Strategy Based on Federation Data Grid Systems (WiMoA 2011 and ICCSEA 2011)

Abstract Data access latency is one of the important factors of system performance in federated data grid. Effective job scheduling can reduce data transfer time by considering bandwidth and also dispatching a job to where the needed data are present. However, different job scheduling strategies resulted in different access latency. This paper proposes a model […]

Matab Implementation and Results of Region Growing Segmentation Using Haralic Texture Features on Mammogram Mass Segmentation (WiMoA 2011 and ICCSEA 2011)

Abstract In digital mammograms, accurate segmentation of tumor is very important stage; therefore we have chosen region based segmentation using haralic texture feature for our research. The main objective of this paper is to identify regions of interest and segment the tumors in digital mammograms. The segmented image is then analyzed for estimating tumor and […]

Available Bandwidth Estimation with Mobility Management in Ad Hoc Networks (WiMoA 2011 and ICCSEA 2011) Part 1

Abstract Audio, video and multimedia applications are traffic type which is increasingly in current networks. Besides the convenience of mobile ad hoc networks consider the provision of quality of service (QoS) essential, that is why several projects have been undertaken to provide it. Among these projects for IEEE 802.11-based ad hoc networks the available bandwidth […]

Available Bandwidth Estimation with Mobility Management in Ad Hoc Networks (WiMoA 2011 and ICCSEA 2011) Part 2

Performances Evaluation of ABE-MM Evaluation Method To evaluate the effectiveness of the proposed mobility management approach in bandwidth measurement, we conducted a comparative experiment using Network Simulator 2 (NS2.34) and the IEEE 802.11 implementation provided with the simulator. The scheme used was (CSMA/CA) without (RTS/CTS) Mechanism. Four constant bit rate (CBR) flows (flow1, flow2, flow3) […]
