To minimize the volume of data to be transmitted, data aggregation is mostly used. As sensor nodes are being deployed in remote and unattented environments, they are prone to node compromise attacks and various other security issues. Hence, it is mandatory that data aggregation protocols must be designed by considering security issues on priority basis. Although, there is a trade-off between data aggregation and security of data, but both aspects are essential. Therefore it is challenging task to maintain data aggregation along with security in these networks. Recoverable Concealed Data aggregation Protocol for Homogeneous wireless sensor networks provides both security as well as aggregation. Despite of its strong security mechanism, this protocol is prone to Packet dropping attacks. This paper aims at detection of packet-dropping attack in Recoverable Concealed Data aggregation Protocol for Homogeneous wireless sensor networks.","PeriodicalId":351783,"journal":{"name":"2015 Fifth International Conference on Advanced Computing & Communication Technologies","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117005064","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}

Various fixed search BME algorithms like TSS, DS etc. Have been proposed in the literature for fast motion estimation but these suffer from over or under search for slow or fast motion video sequences. For quick determination of motion vector of fast moving blocks large search patterns would be helpful but this may cause unnecessary searches for small motion. Therefore a Dynamic Pattern Search algorithm had been suggested that uses the spatial coherence of the left adjacent block and temporal coherence of the collocated block from the reference frame to adjust the search pattern size. Further it was found that large numbers of blocks especially in slow motion sequences are zero motion blocks. Their early determination enhances the speed of motion estimation. A dynamic zero threshold determination model is implemented in this paper to speed up the motion estimation in Dynamic Pattern Search Algorithm. Simulation results clearly indicates 70-95% speed gain for slow motion sequences.","PeriodicalId":351783,"journal":{"name":"2015 Fifth International Conference on Advanced Computing & Communication Technologies","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130195406","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}

Topology update algorithms are periodically run on each participant node of MANET. This period called topology update interval (Δt), is chosen to be uniform. However, neither a high nor a low value of Δt is suitable for a MANET due to unpredictable moving speed of nodes and connectivity ratio and power consumption restrictions. In this paper a method is proposed to dynamically determine the optimal value of topology update interval for k-edge connected topology control algorithm LTRT used in MANETs. The proposed method automatically determines the appropriate value of Δt while ensuring the required connectivity ratio of the whole network for a given node speed and energy consumption goal. The results show that the dynamic method can enhance the network connectivity, allow higher moving speed and improve the performance of network on the same cost, in terms of transmission range that is directly related to power consumption.","PeriodicalId":351783,"journal":{"name":"2015 Fifth International Conference on Advanced Computing & Communication Technologies","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125298999","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}
