Extensive research is being done on Wireless sensor Networks (WSNs) in present decade. WSNs consist of large number of sensor nodes which perform sensing of certain phenomena and send the sensed data to the sinks. This operation consumes energy of sensor nodes which effects the lifetime of a network. To prolong the lifetime of WSNs various strategies and routing algorithms have been proposed. Use of mobile sinks has proved effective in this respect. In this paper we are analyzing the impact of multiple mobile sinks with proactive hierarchical clustering protocols LEACH and network reactive hierarchical protocol TEEN. This paper will give simulation based analysis of using multiple mobile sinks in network and their effect on lifetime of a network. Performance analysis will be done on basis of dead nodes, alive nodes, throughput and residual energy. Read More Read Less

Abstract Multimedia content is now routinely distributed between devices across global networks. These devices differ in their video rendering capability in terms of frame rate, quality, and spatial resolution. To facilitate content exchange between such devices it is necessary to transcode the video format; otherwise no exchange can take place. To prolong battery life on mobile devices, transcoding may take place... Multimedia content is now routinely distributed between devices across global networks. These devices differ in their video rendering capability in terms of frame rate, quality, and spatial resolution. To facilitate content exchange between such devices it is necessary to transcode the video format; otherwise no exchange can take place. To prolong battery life on mobile devices, transcoding may take place remotely on a cloud data center and in which case content protection is advisable. This paper presents an effective multimedia content protection technique that removes the need to decrypt the video prior to transcoding. It does this by partially encrypting the compressed video in such a way that it is decoder-format compliant. The demonstrated scheme allows the transcoder to transrate the video to a desired bit-rate without spending time in encryption/ decryption before decoding the video. In this way, the content and decryption keys are not exposed to third party software at the remote cloud data center and there is no need for complex key management software at the cloud. Consequently, the proposed scheme significantly simplifies cloud-based processing compared to previous schemes. Read More Read Less

Industrial bank played a crucial role in developing the industrial sector which provides about 25% to the GDP and this sector is the main engine of the national economy in Syria. This research aims to apply Total Quality Management to industrial banks of Syria. A random sample of 120 bank employees from higher and middle management were selected to investigate the current situation of TQM in the bank and to develop a new suitable TQM Model. The results show the levels of implementing TQM criteria in the industrial bank, and provide a proposed TQM Model with an implementation plan that could help other Syrian banks to apply TQM in an effective way.
