A Mobile Ad hoc NETwork (MANET) is a collection of wireless mobile hosts that form a temporary network without a centralized administration or wired infrastructure. Due to the high mobility of nodes, the network topology of MANETs changes very fast, making it more difficult to find the routes that message packets use. Network control with Quality of Service(More)
To address deployment schemes over large dispersed geographical area a paradigm shift in the technology was needed. Wireless Mesh Networks (WMN) has emerged as a promising technology to such challenging tasks. As wireless network grows it puts an increased demands in infrastructure based networks.802.11s based WMN is a concrete step that address this(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)
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)
Energy efficiency solutions are more vital for Green Mesh Network (GMN) campuses. Today students are benefited using these e-learning methodologies. Renewable energies such as solar, wind, hydro has tremendous applications on energy efficient wireless networks for sustaining the ever growing traffic demands. One of the major issues in designing a GMN is(More)
The control theory and automation technology is widely used in industries. Many control algorithms are based on the mathematical models of dynamic systems. Mathematical models and parameter estimation are basics for automatic control. A recursive least squares parameter estimation algorithms and Kaczmarz's projection algorithm is applied based on ARMAX(More)
Clustering enables energy constrained wireless sensor networks to consume less battery power for routing the data packets. In order to achieve the key goal of prolonging the lifetime of sensor nodes besides avoiding undesired frequent topological changes, support from clustering mechanism is much appreciable. While proposing clustering mechanisms, attention(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)
