A Dynamic Resource Mapping Load Balancing Technique in Cloud Computing

Research article of American Journal of Computer Engineering A Dynamic Resource Mapping Load Balancing Technique in Cloud Computing Jaimeel Shah1, Dr. Chirag Patel2 1Research Scholar, Parul University,India; 2Associate Professor, Parul University; Tremendous advantages of virtualization and cloud computing innovations have invigorated the Information and Communication Technology sector towards embracing cloud computing. Different ICT-empowered service providers additionally have either embraced cloud computing or began moving administrations to cloud framework. Be that as it may, the expanding interest for cloud based foundation has come about into extreme issue of managing the resources and load balancing for cloud specialist providers and customers. Specialists have recommended various different load balancing techniques for effective resource usage in cloud. An epic load balancing strategy speaking to migration of workload from over-loaded VM to daintily stacked VM in cloud computing condition is introduced in this paper. An endeavor is made to help the cloud partners to overcome the imbalanced resource usage issue is displayed in this paper. Keywords: Cloud computing, Load balancing , task scheduling, task migration ...

Understand Congestion: It’s Effects on Modern Networks

Review article of American Journal of Computer Engineering Understand Congestion: It’s Effects on Modern Networks Omotosho Olawale, Oyebode Aduragbemi* and Hinmikaiye Johnson Department of Computer Science Babcock University, Nigeria As Internet, can be considered as a Queue of packets, where transmitting nodes are constantly adding packets and some of them (receiving nodes) are removing packets from the queue. So, consider a situation where too many packets are present in this queue (or internet or a part of internet), such that constantly transmitting nodes are pouring packets at a higher rate than receiving nodes are removing them (Cardwell, Cheng, Gunn, Yeganeh, & Jacobson, 2016). This degrades the performance, and such a situation is termed as Congestion. Main reason for congestion in a network system is a greater number of packets into the network than it can handle. So, the objective of congestion control can be summarized as to maintain the number of packets in the network below the level at which performance falls off dramatically (Faisal Shahzad1, Ullah, Siddique, Khurram, & Saher, 2015). The nature of a Packet switching network can be summarized in following points: • A network of queues • At each node, there is a queue of packets for each outgoing channel • If packet arrival rate exceeds the packet transmission rate, the queue size grows without bound • When the line for which packets are, queuing becomes more than 80% utilized, the queue length grows alarmingly When the number of packets dumped into the network is within the carrying capacity, they all are delivered, expect a few that have to be rejected due to transmission errors). And then the number delivered is proportional to the number of packets sent (Evans & Filsfils, 2007). However, as traffic increases too far, the routers are no longer able to cope, and ...

Enhancing Networks Lifetime Using Two-Step Uniform Clustering Algorithm (TSUC)

Research article of American Journal of Computer Engineering Enhancing Networks Lifetime Using Two-Step Uniform Clustering Algorithm (TSUC) Vrince Vimal and Madhav J Nigam Department of Electronics and Communication Engineering, Indian Institute of Technology, Roorkee, Uttarakhand, India Wireless sensor networks have enticed lot of spotlight from researchers all around globe, owing to its wide applications in industrial, military and agricultural fields. Energy conservation and node deployment strategies play a paramount role for effective execution of Wireless Sensor Networks. Clustering of nodes in the wireless sensor networks is an approach commenced to achieve energy efficiency in the network. Clustering algorithm, if not executed properly can reduce life of the network. In this paper, a Two -Step Uniform Clustering (TSUC) algorithm has been proposed with the aim to provide connectivity to the nodes in every part of the network. This algorithm increases networks lifetime and throughput by re-clustering isolated nodes rather than providing them connectivity by already connected node. Results obtained after simulation showed that proposed TSUC algorithm performed better than the other existing clustering algorithm. Keywords: WSN, Clustering Algorithm, TSUC, Networks lifetime ...

Underwater Wireless Sensor Networks Challenges: A Review

Review article of American Journal of Computer Engineering Underwater Wireless Sensor Networks Challenges: A Review Taranpreet Kaur Assistant Professor, Dept: Computer Science, Mata Gujri College, Sri Fatehgarh Sahib The underwater wireless sensor network consists of sensors that enable the exploration of natural undersea resources and gathering scientific data in collaborative monitoring missions. Underwater wireless sensor Network consists of variable number of floating and anchored sensors, sink and vehicles that are deployed over an area to be explored. Applications of underwater sensing range from oil industry to aquaculture, and include instrument monitoring, pollution control, climate recording, Prediction of natural disturbances, search and survey missions, and study of marine life. UWSN is a network of autonomous sensor nodes. Which are spatially distributed underwater to sense the water-related properties such as quality, temperature, and pressure? The sensed data can be utilized by variety of applications that can be used for the benefit of humans. The sensor nodes, stationary or mobile are connected wirelessly via communication modules to transfer various events of interest. In this paper, several fundamental key aspects of underwater acoustic communications are investigated. Different architectures for two-dimensional and three-dimensional underwater sensor networks are discussed, and the underwater channel is characterized. The main challenges for the development of efficient networking solutions posed by the underwater environment are detailed at all layers of the protocol stack. Furthermore, open research issues are discussed and possible solution approaches are outlined. Keywords: Underwater Wireless Sensor Networks, Applications and Challenges ...
