In this paper, a novel cross-layer architecture based on the hierarchical protocol structure is proposed to improve the quality of service (QoS) for the video transmission over wireless multimedia networks. In addition, an average bandwidth measurement approach is used to adjust the video delivery immediately. Furthermore, the proposed cross-layer architecture uses both the bandwidth measurement and queue adaptation for the current communication protocol of wireless multimedia networks. Finally, it is shown by NS2 simulations that the methods of both average bandwidth measurement and dynamic queue adaptation do not consume any network resource, and the proposed method can yield a better performance for transmission delay time, image quality and packets throughput over wireless networks. KeywordsCross-layer architecture; bandwidth measurement; queue adaptation; wireless multimedia network

Location aware applications are constantly under development. By using an Indoor Location System (ILS), a user can localize himself, plan an indoor route and destination, or receive useful information and services in malls, airports, shopping centers, etc. To this purpose, various signal strength or timing based localization methods exist, each one having their own advantages and disadvantages. Localization based on the Received Signal Strength (RSS) methods, typically require only off-theshelf equipment to operate. Moreover, they can utilize the existing infrastructure. This paper presents a new method on how to use the captured RSS values for localization purposes. The proposed method analyses a captured signal over a short distance and stores it into the fingerprint database for later comparison, rather than using an average value obtained from static measurements. Performance of proposed method is compared with a typical RSS-based localization method. Real-world measurements are used in order to validate our approach.

Cloud computing has proposed a new perspective for provisioning large-scale computing resources by using virtualization technology and a pay-as-you-go cost model. However, cloud computing is subject to failures which emphasize the need to address user's availability. Availability refers to the system uptime and the system capability to operate continuously. Providing highly available services in cloud computing is essential for maintaining customer confidence and satisfaction and preventing revenue losses. Different techniques can be implemented to increase the system availability. This paper demonstrates one way of implementing highly available virtualized network element using Microsoft Windows Server and Microsoft System Center tools.
