This paper work presents an intelligent hybrid WSN application for an indoor and industrial scenario, with the aim of improving and increasing the levels of human safety and to avoid the denial of service (DoS) attacks. Since its operates on a wireless network, an adversary can always perform a DoS attack by jamming the radio channel with a strong signal. The main contribution of our work is to use a hybrid approach that handles the problem of jamming. The proposed solution improves security by protecting against DoS and returns near-optimal solutions. The paper shows the viability of our approach in terms of performance, scalability, modularity and safety.","PeriodicalId":412982,"journal":{"name":"2016 World Symposium on Computer Applications & Research (WSCAR)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130213089","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 sciences use algorithms to analyze, and predict a hypothesis for the huge collected biological data in gene banks. Sequence alignment is the most important topics in bioinformatics which we are concerned with it in this paper. In comparison of bimolecular sequence (i.e.,DNA, RNA, and protein), regions of sequence similarity indicate functional and structural similarity. As a result, Sequence comparison is the main problem in computational biology, such as evolutionary tree reconstruction, genome analysis, and classification of viruses that belong to specific family of viru+ses. So, it is very important to relate common matched parts between DNA or Protein sequences or to determining ancestors sequences of an offspring before it is used in any process. Due to database was large, parallel smith waterman algorithm (SW) we implemented on Field Programmable Gate Arrays (FPGA) to decrease execution time of algorithm, Which gives significant reduction of execution time and sequential (SW) Execution time by half for two parallel process and decrease the FPGA utilization by 65%.","PeriodicalId":412982,"journal":{"name":"2016 World Symposium on Computer Applications & Research (WSCAR)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132735279","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}

Before that, SnS was deposited on indium-tin-oxide (ITO) coated glass substrate by electrochemical deposition (ECD) method. Hence, the ZnO growth properties were investigated from surface morphology, X-ray diffractometer (XRD) spectra, thickness, chemical composition and current density-voltage (J-V) measurement. The ZnO samples were deposited using three various deposition times, which are 10 hours, 20 hours and 30 hours at solution temperature of 90 °C. Then, the growth properties were investigated using field emission scanning electron microscope (FESEM), XRD, current-voltage (I-V) two point probes, energy dispersive X-ray Spectroscopy (EDX) and surface profiler. The thickness of ZnO/SnS heterojunction was 1.25-2.00 µm and the diameter of ZnO nanorods were 1.11-2.92 µm. All of ZnO peaks observed from XRD corresponding to the wurzite structure and all of SnS peak corresponding to orthorhombic structure.

Data are digitized at a sampling rate of 100 samples per second with a High Resolution Digitizer (HRD) or Trident Digitizer from NANOMETRICS. A new algorithm is proposed for the digitized data packets using a variable packet length which is better than fixed packet length since it is errorless (lossless) in samples. Also the new algorithm saves the bits wasted due to the old compression algorithm.

Steganography involves hiding information in a cover media to obtain the stego media, in such a way that the cover media is perceived not to have any embedded message for its unintended recipients. In this paper work, we provide a critical review of the steganalysis algorithms available to analyze the characteristics of an image stego media against the corresponding cover media and understand the process of embedding the information and its detection.

Due to limited transmission power, wireless multihop transmissions of sensor data messages to the sink node are mandatory. Thus, low-power forwarding based on intermittent communication in each intermediate wireless sensor node is required. However, it is difficult for intermediate wireless sensor nodes to select their next-hop node since on-off intervals and current locations of their neighbor wireless sensor nodes are not always achieved due to the intermittent communication environments. This paper proposes a novel probabilistic next-hop selection and evaluates the performance improvement, i.e., reduction of transmission delay and battery power consumption.","PeriodicalId":412982,"journal":{"name":"2016 World Symposium on Computer Applications & Research (WSCAR)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115640160","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}
