Dynamic source routing protocol (DSR) is an on demand routing protocol that is deemed a suited reactive routing protocol for MANET. Mobile ad hoc network is composed of independent devices communicating with each other directly without the help of any constant infrastructure or centralized administration.In general some nodes in network cut off working because battery run out of power, therefore it is much important to preserve the energy. DSR suffers from energy depletion and that because DSR routing protocol doesn't take the term of energy consumption as a parameter into account at all. DSR routing protocol has main advantages to supply path and transmit data packets from source to destination but its disadvantage is transition energy which is forfeiture when the data packets are drop or when the acknowledgement not receive by neighbor nodes that time these paths not efficient for data packets. This paper presents a summary of different energy efficient protocols that are based on the basic technique of DSR and expands the endeavor and pledge that has been made since last 8 years to turn the conventional DSR as energy efficient routing protocol.
Migration of virtual machine is one of the most important features in virtual machine technology .It involves moving a VM from a physical host to another, facilitating balancing load, utilization of resource and reducing energy consumption. The goal of this paper is to present a survey of the main types of virtual machine live migration, their classifications and a comparative study of these techniques in a particular class. It also discusses the algorithms used in virtual machine migration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
