Mobile ad-hoc network (MANET) communication is challenging as they are dynamic in nature. We propose a MANET routing protocol considering the QoS (Quality of Service) parameters such as bandwidth efficiency, link stability and power metric. The idea of learning the network status information to enhance network routing is the key concept of our project. This(More)
A new scheme that serves to find a routing path for Wireless Sensor Networks (WSNs), with a view to facilitate an increase in the network life time is proposed in this paper. It envisages the network to be in the form of clusters and develops an algorithm for transfer of information within the nodes and to the remote Base Station (BS). The approach involves(More)
The emergence of multimedia applications demands multicasting in MANETs. For such applications QoS provisioning is a complex and challenging issue. This paper proposes a QoS aware multicast routing scheme uses a set of static and mobile agents and ensures QoS guarantees in terms of bandwidth reservation, delay constraint, delay-jitter constraint and packet(More)
Infrared thermography is recently widely accepted as a medical diagnostic tool. Thermographs are acquired for the whole body or the region of interest. Thermographs are processed for abnormality detection and quantification. As temperature variations are not normally visible to naked eye it is necessary to develop and analyze the feature extraction(More)
514 Abstract—Infrared thermography, non-contact, noninvasive technique is widely accepted as a medical diagnostic tool. An IR camera captures heat variations from the skin and maps into thermographs. Thermographs are acquired for the whole body or the region of interest. Thermographs either gray scale or pseudo color are processed for abnormality detection(More)
This paper attempts to develop a scheme that facilitates data transfer between the various nodes in an energy constrained Wireless Sensor Network (WSN), with a view to increase the life time of the network. The philosophy is based on optimising the product of energy and delay besides ensuring an enhancement in the performance of grid networks. It envisages(More)

Model predictive current control of a five-level cascaded H-bridge (CHB) inverter with different sampling times is presented in this paper. The purpose of the current controller is to regulate the load current within the set reference current. A simulation model of the five-level CHB inverter with Model Predictive current controller (MPC) has been built to(More)
