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)
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)
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)
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)
The paper proposes the development of an energy efficient multipath routing protocol with directional antenna for MANET as an optimization task as well as a multidisciplinary entity. A comprehensive analysis to link all the multidisciplinary viewpoints involved in the development of desired multipath routing protocol with requisite technical details is(More)
Optic flow is the apparent visual motion that one experiences during motion. A fundamental problem in Machine Vision and processing of image sequences is the estimation of the optic flow, which is the projection of the 3D surface point motion on a 2D sensor plane. This paper deals with the phase based algorithm for optic flow computation. The phase based(More)
