Energy conservation for WSNs is a primary objective that needs to be addressed at all layers of the networking protocol stack. In many applications latency is another crucial factor to be addressed. However this must be done in the context of the energy constraints imposed by the network. In this paper we present an experimental evaluation of two node scheduling regimes within MERLIN (MAC energy efficient, routing and localization integrated), an energy-efficient low-latency integrated protocol for WSNs. In particular we contrast the X and V scheduling family schemes with respect to the following properties: network setup time, network lifetime and message latency. We conduct our experiments within the OmNet++ simulator.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126867880","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 twin class uniform and nonuniform partitioned M-level Quadrature Amplitude Modulation (QAM) system is used to transport a compressed video bitstream which is partitioned to match the bit-error sensitivity of the transmitted symbol in terms of mapping in the constellation diagram and picture quality. The partitioning scheme is based on a separation of the Variable Length (VL) coded Discrete Cosine Transforms (DCT) coefficients within each block, and is applied to split the ITU-T H.263 coded bitstream. Various scenarios for splitting the bitstream are investigated and their results are compared and analysed thoroughly. The performance of the transmission system is evaluated under Additive White Gaussian Noise (AWGN) conditions. The results show video partitioning forms an effective method for transmitting video information over mobile channels.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123434036","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}

Systems specifications provide the basics and framework to design an effective system, and for wireless intrusion detection systems, this assumes greater importance due to the complexity of wireless environments, and the architectural and functional constraints created by such environments. In the light of this, this paper discusses the architectural and functional issues involved in intrusion systems design for mobile and adhoc networks (wireless environments); and also proposes a new way of making systems requirements specification more effective and responsive to the needs of wireless implementations.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129179992","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}

It enhances reliability and security also. The proposed change detector employs a neural network function prediction in order to determine if the sensor outputs have changed In addition to the change detection system, a modification to a standard neural network function predictor is proposed that allows the change detection system to quickly learn how to accurately predict next sensor outputs. The parameter choice and the relationship between the threshold values and false alarm and change missing rates are studied The protocol is implemented and tested in real life environments with sensor networks built from Crossbow MICA-2 motes. Sensor network change detection system, which is designed to become a protocol core utility, is described The test results are analyzed and recommendations on applications are derived.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127628768","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}

In particular, perceptual quality assessment methods are required to measure the overall perceived service quality based on the grading given by human subjects. This paper focuses on the development of a reduced-reference perceptual image quality metric, which can be applied for in-service quality monitoring and link adaptation purposes. In contrast to the conventional image fidelity metrics such as the peak signal-to-noise ratio (PSNR), the proposed hybrid image quality metric (HIQM) takes the human perception into account. In addition, HIQM does not rely on the availability of the full reference of the original image at the receiver.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122336719","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}

Sensor nodes are resource constrained from many aspects.

Our detection algorithm keeps short-term dynamic statistics using a multi-level, sliding window event storage scheme. In this algorithm, arrival processes at different time scales are compared using node resourcewise computable, low-complexity, aggregate features.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128668554","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}
