In channelization the videos are partitioned into segments and the bandwidth of the physical channel is partitioned into logical channels. The first segment of each video is transmitted through the first logical channel, the second segment of each video through the second logical channel, and so forth. The segments are transmitted periodically through the logical channels. In this paper, the video signals to be transmitted through different logical channels are estimated. Furthermore, using the Hilbert transform the phase is estimated by incorporating the jitter delays occurring among the video segments while transmitting through the logical channels. The phase is helpful in estimating the storage space at the user's site so that continuous delivery of the video services can be maintained","PeriodicalId":257948,"journal":{"name":"2007 International Conference on Signal Processing, Communications and Networking","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131417100","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}

Clustering sensor nodes is an effective technique to achieve these goals. This paper assumes a heterogeneous network structure where nodes with higher capabilities act as cluster heads and others as members of the cluster. Nodes use multi hopping to reach the cluster heads and hence the cluster heads and the nodes closest to them decide the lifetime of the network. The contributions of this paper are: (i) it outlines the design issues to be considered in optimizing the performance of large-scale wireless sensor networks operating under energy and reliability constraints, (ii) It provides a model to calculate the optimum number of clusters to guarantee a minimum lifetime and validates the model using a simulation study","PeriodicalId":257948,"journal":{"name":"2007 International Conference on Signal Processing, Communications and Networking","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134642457","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}

However, multiple access interference (MAI), which increases with the number of simultaneous users, severely limits the capacity of the system. Optical parallel interference cancellation (OPIC) has been used to reduce the effect of MAI. The drawback of OPIC is that, it increases the demand for hardware complexity, resulting into higher processing time and cost. To overcome these difficulties, an efficient method is presented in this paper called, one stage optical parallel interference cancellation (OS-OPIC) which is based mainly on OPIC. Performance analysis of the proposed design is done using optical orthogonal code (OOC) as signature sequence and new expression for error probability is demonstrated. It is shown that, the proposed method is effective to reduce the hardware complexity, processing time and cost while maintaining the same bit error probability at the cost of increasing threshold value","PeriodicalId":257948,"journal":{"name":"2007 International Conference on Signal Processing, Communications and Networking","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114858105","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}

IP packet traceback is usually performed with the help of routers and gateways. Several approaches have been proposed to trace IP packets to their origin. The packet marking approach enables routers to probabilistically mark packets with partial path information and tries to reconstruct the complete path from the marked packets. In most of these approaches, routers and victims (affected systems) are considerably overloaded for marking the packet and reconstructing the trace path and requires more marked packets. This paper focuses on tracing the approximate source of attack instead of tracing the entire path in multi domain system without computation, by victim and also implementing security for authentication and confidentiality.

In recent years, low power wireless communication and the availability of cheap and small micro sensor nodes lead to enhanced developments of wireless sensor network applications in real society. The energy constraint inherent in the small battery powered nodes presents a considerable problem, and much effort is being put into reducing the power consumption. We introduce a reactive routing protocol called energy aware routing that is intended to provide a reliable transmission environment with low energy consumption. This protocol efficiently utilizes both the energy available in the node and quality of the link to identify the best possible route to the destination. Simulation results show that the energy aware routing scheme outperforms the existing schemes even in the presence of high node density and overcomes simultaneous packet forwarding","PeriodicalId":257948,"journal":{"name":"2007 International Conference on Signal Processing, Communications and Networking","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128964756","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}
