Wireless Sensor Networks (WSNs) are battery-powered ad-hoc networks in which sensor nodes are scattered over a region. These networks have high node density but highly resourceconstraint in terms of size, power and bandwidth. Most of the existing sensor networks focus on homogeneous sensor networks, but these networks have poor performance in terms of energy consumption and network life time. S...

Mobile ad hoc networks (MANETs) consist of wireless mobile nodes that can dynamically and freely selforganize into arbitrary and temporary ad hoc network topologies. Due to high mobility of nodes, there exist frequent link breakages which lead to frequent path failures and route discoveries. In a route discovery, both cluster and broadcasting scheme is deployed, where a mobile node blindly rebr...

Cloud computing requires more reliable, efficient and scalable load balancing algorithm to survive. As one of the main challenges in cloud computing, load balancing facilitate dynamic workload across multiple nodes ensuring that no single node get overloaded. With proper load balancing, resource consumption is maintained at minimum level, enabling scalability, avoiding bottleneck and overprovis...

In the past decades, Wireless Sensor Network (WSN) has become a wide area of research. In WSN, numerous sensor nodes are randomly setup with different energy level. Energy acts as power source and is available to each sensor node in limited quantity. The limiting factor is that sensor nodes are energy constrained and recharging or replacing battery is costly and complex process. This paper expl...

The fast growing demand for computational power utilized by modern applications with rapidly changing Cloud computing technology have directed to the foundation of large-scale virtualized data centers. Such data centers consume massive amounts of electrical energy resulting in high operating costs and carbon dioxide (CO2) emissions. Dynamic consolidation of virtual machines (VMs) using Dynamic ...

A hierarchical control architecture for balancing comfort and energy consumption in buildings is presented. The control design is based on a simplified, yet accurate model of the temperature within each room of the building. The model is validated against real measurements. The control architecture comprises a first level that regulates low level quantities such as air flow, and a second level ...

Global routing protocols in wireless body area networks are considered. Global routing is augmented with a novel link cost function designed to balance energy consumption across the network. The result is a substantial increase in network lifetime at the expense of a marginal increase in energy per bit. Network maintenance requirements are reduced as well, since balancing energy consumption mea...

Hotspots of energy consumption and network congestions can be caused by load imbalance among sensor nodes in wireless sensor networks. This may lead to loss of data packets and premature death of sensor nodes which may cause the premature death of entire network. Load-balancing techniques can prolong the lifetime of sensor networks and avoid the occurrence of packet congestions. This paper prop...

Wireless Sensor Network (WSN) is becoming a very important area of research in today’s world and contributes a lot in the field of technology. Reducing energy consumption and improving the network lifetime is the key factor to be considered. In this paper, we propose a new protocol namely Minimizing Energy Consumption Using Unequal Clustering (MECUC). MECUC attempts to improve energy efficiency...
