In this protocol, all the nodes of the networks are clustered into a single cluster; we have analyzed the way how to compute the trusting values according to their interaction performances between the nodes. Based on the trusting value, we can decide and check whether the connection between the two nodes is reliable or not. On the basis of no. of reliable connections, we can choose the cluster head in the cluster, and the nodes which hold solid association with cluster head will be the base nodes, base nodes and the cluster head can work together for being the service providing congregation (group) for the cluster. Each member will circulate a secret share mechanism which will be a part of secret key for itself, and come into being the parameter of authentication in the processing of investigation about the up to date requirement in the next cluster, and the obscure and secret share mechanism can also be authenticated by the node itself. One node has been confirmed as a malicious node at a time; cluster head broadcasts the information to all the cluster members and refuse to provide updating service for the particular malicious node. The protocol has absolute forward confidentiality and backward confidentiality. The keys of nodes and cluster are generated after discussion among the service group members, Man-in-the-middle attack can be resisted by this way. At the same time, the cluster can achieve the periodic update, the cluster head will be reelected, service group will be reformed, subsequently, the key of cluster and nodes will be updated as well.","PeriodicalId":166244,"journal":{"name":"2017 International Conference on Recent Innovations in Signal processing and Embedded Systems (RISE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114181428","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}

Sawale","doi":"10.1109/RISE.2017.8378142","DOIUrl":"https://doi.org/10.1109/RISE.2017.8378142","url":null,"abstract":"Kernel based methods are most popular non parametric estimators. There are various types of kernels which are used for filtering the video sequences. Gaussian kernel filtering is widely used method to remove unwanted fluctuations present in the video sequences because they are simple to implement. Gaussian filters are designed to give no overshoot to a step function input while minimizing the rise and fall time. This behavior is closely connected to the fact that the Gaussian filter has the minimum possible group delay. But the use of the large gaussian kernel might lead to the blurring effect and small gaussian kernel may not effectively remove the high frequency camera motion. Hence it needs to find the optimal value of gaussian kernel. Most of previous methods suffer from the problem of the large missing image areas. Temporal mean or median filter is the optimal approach to removing the noise when the corrupting noise on each video frame is identically and independently drawn from a zero mean distribution. But they have limited performance for smoothing the inter frame motion. The paper discusses the mean, median and gaussian kernel filters for smoothing the video sequences. First video sequences are stabilized using hierarchical global motion estimation and then kernel filtering is used to remove the accumulation error. The performance of the gaussian kernel filtering is then compared with the mean and median filters. Motion in X and Y direction after estimation and compensation is compared for different gaussian kernels. Proposed video stabilization technique is experimented on the large variety of videos taken in real time environment with different motions.","PeriodicalId":166244,"journal":{"name":"2017 International Conference on Recent Innovations in Signal processing and Embedded Systems (RISE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128744709","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}

These processors provide high performance by executing programs independently on multiple cores. Multithreading helps programmer to execute tasks independently by utilizing underlying computing architecture appropriately. Multiple threads share common memory space. Shared memory architectures face the problem of cache coherence. Different techniques has been devised to keep caches coherent. These techniques have their own advantages and disadvantages. The prime aim of computer architects is to provide a much better computing environment along with high performance and less energy consumption. The processors required for smart phone devices have major concern with energy efficiency. Recent research shows that hybridization of cache coherence techniques is being carried out to achieve the goals like high performance, energy efficiency and scalability. This work gives a focus on analysis of existing cache coherence techniques independently. These techniques can be integrated together for hybridization of cache coherence techniques. In particular, the issues like performance analysis and energy consumption of snoopy and directory based cache coherence variants are addressed. Snoopy protocol performance gets affected due to on-chip traffic. It has been observed that MOESI CMP Token cache coherence protocol is energy and performance efficient than all other variants.","PeriodicalId":166244,"journal":{"name":"2017 International Conference on Recent Innovations in Signal processing and Embedded Systems (RISE)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123823619","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}

Pilot contamination is nothing but the interference caused by reuse of the pilot sequences to accommodate more number of users. Contaminated pilot results in poor channel estimation at the BS (Base Station). Addressing the problem of pilot contamination is the prime concern in Multicell Massive MIMO system. In the proposed scheme, instead of transmitting pilot sequence synchronously by all user terminals of all the cells, time shifted pilot sequence transmission in a non-overlapping time interval along with pilot sequence hopping is used at each coherence interval. Pilot sequence hopping causes random position of interfering user terminals. Therefore, changing the channel coefficient in each transmission slot, which results in better channel estimation as the group of interfering user terminals changes. At the BS, Mean Square Error (MSE) which is the measure of channel estimation and Pilot signal power to Interference power Ratio (PSIR) are calculated for less aggressive frequency reuse factor for the pilot sequences.","PeriodicalId":166244,"journal":{"name":"2017 International Conference on Recent Innovations in Signal processing and Embedded Systems (RISE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126523414","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}

Connectivity breaks between nodes, resulting from random fashioned nodes movement, are a serious problem for MANET routing protocols. Though, sometimes the selected routes which are based on hop count are having weak quality links, implies low SNR, which results higher rate of frame error, higher end to end delay and lower throughput. This present mechanism permits the network layer to modify its routing protocol dependent on Received Power and SNR along the source to destination route for every transmission link. This proposed routing method uses signal-to-noise ratio (SNR) of a link for getting value of its sojourn time and allot a link cost value on the basis of calculated sojourn time. Sojourn time is assumed to follow a Rayleigh distribution. Link cost is inversely proportional to sojourn time. Node which is connected to its previous node with less link cost is chosen as next neighbor node on the way of source to destination route establishment. The performance analysis was evaluating our approach (Sojourn Time-ST-AODV) and AODV, to illustrate that our proposed methodology improved the performance of AODV. Finally, justify network performance on NS-2 network simulator platform depending on the basic network parameters such as delay and throughput in respect of nodes and different transmission rates of mobile nodes.","PeriodicalId":166244,"journal":{"name":"2017 International Conference on Recent Innovations in Signal processing and Embedded Systems (RISE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128907668","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}
