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)
Nowadays Infrared thermography is 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)
Towards wireless communication, efficient spectrum or radio resource management is of paramount importance due to ever increasing demands for communication services. The key allocation decisions of radio resource managements are connected with channel assignment and the transmitted powers. In DS-CDMA systems spectrum utility is not a problem. With tight(More)
— Infrared Thermography can be used as a diagnostic procedure for determining abnormality in human. Thermographs provide the thermal mapping of the area under observation. For normal cases, thermographs show uniform and symmetrical temperature distribution. An abnormality appears as an abrupt temperature variation in thermographs. Quantitative(More)
A wireless based mesh network has been considered as a viable option to provide coverage for a vast area. Interference due to multi hop transmission and potential isolated nodes are the major obstacles to achieve high performance. In order to avoid problem related to multi hop transmission we adopt a heterogeneous Wi-Fi mesh network which can provide more(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)
