The Human hand is versatile in its interaction. Imitating the versatilities and human dexterity in robotic design is a huge challenge, and requires a great depth of understanding of the human upper limb physiology and its robotic equivalent. A huge amount of research worldwide is being carried out in order to develop a human hand like prosthetic which can(More)
With unprecedented growth of the subscribers in modern cellular and wireless data communications, there is an acute scarcity of additional bandwidth to meet the ever growing demand. To ease the constraint of additional bandwidth, utilization of the existing system has been a topic of recent interest. Cognitive Radio is a new technique in which the spectral(More)
Convergence of Internet Protocol based networks is a necessary requirement today. One important aspect of convergence is seamless integration of wired- wireless network. Internetworking of wired-wireless network is important from Quality of Service (QoS) perspective. Providing a wired network support to an overloaded wireless network for load sharing,(More)
In this paper a method of collision detection and retransmission of broadcast packets is proposed. In multi-hop wireless networks, broadcasting is an elementary part of the routing process. However, due to the hidden node problem, broadcasting often leads to collisions. In the presence of broadcast collisions, a node cannot populate its neighbor table(More)
In this paper, a reconfigurable hand Gesture Recognition System (GRS) has been designed and developed for multiple applications using vision based techniques. Image is acquired from the camera and processed using a DSP processor in real time. Processing involves image segmentation and palm extraction techniques for extracting palm shaped objects from the(More)
This paper deals with a distributed clustering approach to tackle greedy clustering heuristics in MANETs. One of the most commonly used techniques to cluster nodes in a network is the Multiple Weighted Clustering (MWC) algorithm, which considers distinct heterogeneous performance metrics in a weighted form to select a Cluster-Head (CH). Since, clustering is(More)
Routing is an essential part of data exchange in Mobile Ad-hoc Networks (MANETs). A protocol that can discover multiple routes from source to destination can support reliable routing of information in MANETs. However, a reliable routing protocol alone cannot enhance performance of MANETs. Nodes in MANETs also experience the problems of interference, exposed(More)
Directional antennas have gained immense popularity among researchers working in the area of wireless networks. These antennas help in enhancing the performance of wireless networks through increased spatial reuse, extended communication range, energy efficiency, reduced latency, and communication reliability. Traditional Medium Access Control (MAC)(More)
Due to increasing popularity of Mobile Ad hoc Networks (MANETs), research in this area has constantly strived to improve performance of these networks. In this paper Dual Polarized Directional Antenna based Medium Access Control (DPDA-MAC) protocol is presented to enhance the throughput of MANETs. Nodes operating in accordance with DPDA-MAC are capable of(More)
