Virtualization stands as a key enabling feature of cloud computing. Resource needs are not static due to the diversity of applications and need to manage resources dynamically. To achieve dynamic resource management there is a need to increase the performance of resource allocation for different resources requested by the client through better allocation of virtual machines to the host, performing the migration of a VM from one host to the other. Server consolidation is done to power off the least utilized nodes when the workload concentration is fewer in certain nodes to reduce the carbon emission. This approach increases the utilization of cloud resources even in idle periods by forming virtual clusters.","PeriodicalId":325520,"journal":{"name":"2014 Sixth International Conference on Advanced Computing (ICoAC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121902828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They need to gather the data from the surrounding environment, and they need a sensor interface. These robots can be worked with IoT environment. In fact, in traditional methods the number of sensors connected are minimized, sampling rate is less and even has a restriction over types of signal in sensors. Using reconfigurable smart sensor interface the complexity of the code can be reduced in IoT environment. In the proposed system, FPGA is taken as the main logic controller. It can parallel process the data in real time. It is smaller in size and has finer grain capability. It works faster than CPLD. This system uses IEEE1451.2 standard; this gives an intelligent sensor interface between sensors in robot. On the whole, it comprises both the hardware and software for a clever acquisition of information by common sensors. It is practically applied in disaster management control with good performance, and it can be also used in industrial and medical environment.","PeriodicalId":325520,"journal":{"name":"2014 Sixth International Conference on Advanced Computing (ICoAC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123067909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each cluster head receive a different form of data among individual sensor nodes and from other neighborhood cluster head, which leads to loss in accuracy of data. Multihop transmission to the base station will cause loss in actually sensed data. In this paper, Enhanced Reprogramming Technique (ERPT) is to maximize accuracy of data with minimum energy utilization. In our approach, two levels of aggregations are performed. One is an intra-cluster aggregation within the cluster head and inter-cluster head aggregation are performed from one cluster head to another cluster head. It improves network lifetime by reducing the amount of traffic among individual sensor nodes to the base station because sensor nodes are resource constraints. Increasing number of nodes among sensor network will maximize the accurate data, but it leads to more energy consume. This will be improved by enhanced reprogramming. The proposed technique addresses the scalability issues with minimized energy consumption compared to traditional approaches.","PeriodicalId":325520,"journal":{"name":"2014 Sixth International Conference on Advanced Computing (ICoAC)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123554760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence an efficient management and sharing of bandwidth among the users is essential to improve the performance of networks. There are so many techniques are available to estimate the available bandwidth, but most of the techniques fail to estimate available bandwidth in a wireless resource constrained network due to the increased variability of wireless channel conditions and variable bit rate. To improve the accuracy in Available Bandwidth Estimation, the proposed system estimate Service Process and Effective Service Curve for a variable bit rate (VBR) flows using stochastic process model. The random factors incoming data rate ri and outgoing data rate ro are used to determine the flows. By increasing the accuracy of the bandwidth estimation, the end to end throughput is increased and delay is minimized in MANET.","PeriodicalId":325520,"journal":{"name":"2014 Sixth International Conference on Advanced Computing (ICoAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130222887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intruder nodes simply communicate with any node in the zone, thus compromising the nodes and in turn spoiling the nature of the network. To reduce the damages be fallen on the compromised nodes, it should be successfully detected and revoked as soon as possible. Range of node specifies detection systems in wireless ad-hoc and sensor networks have been projected by academicians, of late. In the existing approach Leader based intrusion detection system is used to find out suspect regions where the compromised nodes are ensconced, here the Leader will be elected region wise based on the energy level to detect the attacker and revoke the compromised node. To overcome this as well as to provide high security two new stage approaches are proposed. They are the DPFM-[Data Packet Format Matching] method which detects the attacker node and DAA-[Divert Attention Attacker] method which prevents nodes compromising in the zone. The simulation result shows that the compromising node is eliminated and attacks are controlled in the network.","PeriodicalId":325520,"journal":{"name":"2014 Sixth International Conference on Advanced Computing (ICoAC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128464401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problems in the traditional recommender systems such as cold start and scalability are addressed. The system accommodates a trust factor in the classical recommender system and reaps the efficiencies of the k-means++ algorithm, which provides the threshold rating for the cold start users.

Introduction of a proxy for spatial query processing reduces the number of queries submitted by the mobile clients to provide the relevant results. Hence, proxy based approach is prefered to server based approach. This is done to the reduction in waiting time of the query retrieval by proxy. Morover, it reduces the server load in mobile environments. Continuous Nearest Neighbor query processing increases the server load done to the number of consecutive queries submitted by the mobile client who tries to get the desired results. The mutual support between the results of the nearest neighbor queries and window queries are used to enhance the performance. Caching a number of queries in the cache leads to performance degradation. This is overcome in this work by using a cache replacement technique, and hence this system improves the performance of the spatial query processing.","PeriodicalId":325520,"journal":{"name":"2014 Sixth International Conference on Advanced Computing (ICoAC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134353149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The designing of a thermometer code to binary code is one of the bottlenecks in achieving high speed. The modus operandi involved in this process is that an encoder circuit translates the thermometer code into the gray code to reduce the effect of meta-stability and reduction of bubble errors. And also that low power and high speed encoder is designed by deploying a new logic design style to implement conversion of the thermometer code to binary code through differential cascade voltage switch logic (DCVSL). However the encoder proposed is designed by using Cadence 180 nm CMOS technology with a supply rail voltage typically ±0.5 V.
