Channels Reallocation In Cognitive Radio Networks Based On DNA Sequence Alignment

Nowadays, It has been shown that spectrum scarcity increased due to tremendous growth of new players in wireless base system by the evolution of the radio communication. Resent survey found that there are many areas of the radio spectrum that are occupied by authorized user/primary user (PU), which are not fully utilized. Cognitive radios (CR) prove to next generation wireless communication system that proposed as a way to reuse this under-utilised spectrum in an opportunistic and non-interfering basis. A CR is a self-directed entity in a wireless communications environment that senses its environment, tracks changes, and reacts upon its findings and frequently exchanges information with the networks for secondary user (SU). However, CR facing collision problem with tracks changes i.e. reallocating of other empty channels for SU while PU arrives. In this paper, channels reallocation technique based on DNA sequence alignment algorithm for CR networks has been proposed.Comment: 12 page

Network Engineering through Skip List Data Structure for Federated Cloud Data Center

Now a days we can see that Cloud computing is fastest growing platform for making resources available to the users CC is based on internet computing that is enormous group of remote servers are network that allow centralized the data store and access. In terms of cloud computing this background network is known as Data Center Network. In this paper we have explain Skip List Topology because this topology in the account as the size of list is dynamic and it is very easy to insert and searching data in the list it is apparent that Skip List is better in term of efficiency B-tree

A Approach to Optimal Strategy for Energy Efficiency in Cloud System

Cloud is a combination of datacentre software and hardware. People may be provider, user of SaaS, users or providers of Utility Computing. Most of the energy in system devices is squandered because they are built to deal with worst case scenario. Different scheduler like SJFGC, DENS, and DCEERS are reported by different researches. Green CloudSim makes total of energy utilization information in data centre. It is utilized by communication and computing components of the data centre possible on an unprecedented fashion. In the paper comparision of total energy consumed by two scheduling viz. Random and RandomDENS algorithms is presented
