A Wireless Multimedia Sensor Network (WMSN) is a network of wirelessly interconnected devices i.e. sensor nodes that are able to retrieve data from environment in the form of audio/video streams, still images and scalar sensor data. Secure routing in WMSNs faces more challenges than those in traditional sensor networks because of multiple sink nodes and(More)
Wireless Networks are the most popular networks now a days due to their less cost and easy deployment anywhere. The carrier sense multiple access with collision avoidance (CSMA/CA) protocol is a random access protocol that is used to avoid collisions in wireless local area networks (WLANs). In this paper, a detailed performance evaluation of IEEE 802.11(More)

Methods: This Descriptive case series was carried out in 150 consecutive patients undergoing laparoscopic cholecystectomies for gall stone disease in Services institute of Medical Sciences, from December 2012 to June(More)
Robotic exoskeleton arms have been around for a long time and they have successfully evolved from research prototypes to commercial products. Multipurpose supernumerary robotic limbs (MSRLs) have been recently introduced as new types of aids which do not directly replace missing limbs, but they are additional mechanical arms with changeable end-effectors(More)
This paper is about the client/server model of security with Bar-coded Identity Cards. Client and server are not just two words put together but it includes a vast range of softwares by having a backbone of client/server database. By making a client/server database we have implemented our project with a new perspective. We have developed a compact and(More)
