The approach which is used to derive the aggregation formula is minimum relative entropy inference. Based on the relative entropy, we introduce an end-to-end arithmetic. The main idea of our arithmetic is to regard the average packet loss ratio and RFD as two decision makers. Those two decision makers give opinions to the network status separately; utilize the principle of relative entropy to infer the best choice of the network status. Therefore, we can differentiate the character of losses using decision-making. Our simulation measurements suggest that this arithmetic can work well in differentiating losses and throughputs.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121414580","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 this paper, we introduce WiSNAP (Wireless Image Sensor Network Application Platform), a Matlab-based application development platform intended for wireless image sensor networks. It allows researchers and developers of such networks to investigate, design, and evaluate algorithms and applications using real target hardware. WiSNAP offers standardized and easy-to-use Application Program Interfaces (APIs) to control image sensors and wireless motes, which do not require detailed knowledge of the target hardware. Nonetheless, its open system architecture enables support of virtually any kind of sensor or wireless mote. Several application examples illustrate the usage of WiSNAP as a powerful development tool.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129999680","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}

Experimental results show that this algorithm has good imperceptibility and robustness against various interference (A-law/U-law compression, low-pass filtering, white noise, etc) when the speech is transmitted over the public switching telephone network (PSTN). This algorithm can be widely used in secure voice communication and fax systems.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124564179","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}

All nodes are assumed as mobile and run the same CLP algorithm in . An initial seed triggers six neighboring nodes to move to hexagon permutation positions, which is like the Crystal-Lattice formation process in nature. These chosen nodes then become new seeds to trigger other neighboring nodes. By such a progressive process, with initial and boundary conditions, the coverage is achieved. Comparing to the Virtual Force algorithm (VFA), the CLP algorithm needs fewer nodes and takes shorter average moving distance to achieve 100% coverage in random deployment. In simulation, the CLP algorithm deployed at least 60 nodes to achieve the 100% coverage, while the VFA algorithm required more than 100 nodes, under the same assumptions. The average moving distance for each CLP node was less than a half of the VFA node. In addition, as there are n mobile nodes, the number of CLP messages is proportional to n, while VFA is proportional to n2. The CLP algorithm is robust in fault tolerance when some nodes are error in distribution.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132387559","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}

Researches in context aware mobile learning have concentrated on how to adapt applications to context.

Furthermore, it proposes an ubiquitous middleware, a new multi-layer conceptual framework for building contextaware mobile learning systems. This framework supports tasks including: acquiring, interpreting, modeling, storing, reasoning, updating and adapting context. The originality of this framework comes especially from its top-most layer which is an adaptor that defines two classes of functionalities: the adaptation of learning activity to context and the adaptation of context to learning activity.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"431 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132027701","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 demand for high-performance in-line bandwidth controllers is driven by the growing bandwidth available in the last mile WAN links as well as the sophisticated packet processing functions that become essential in current computer networks. In this paper, we propose an adaptive clustering scheme to scale the throughput of in-line devices and implement the bandwidth control functions over a cluster of in-line devices. The proposed scheme aggregates the processing power of multiple in-line devices in the cluster by making incoming traffic self-dispatched in a transparent fashion, and incorporates a flow migration mechanism that keeps the load of each device balanced. The resulted cluster is also able to tolerate device failures and hence is run-time reconfigurable. Based on the proposed scheme, we successfully design a distributed policy adjustment algorithm, the proportional bandwidth allocation algorithm, and implement a clustered bandwidth controller over embedded Linux. The results of performance evaluation suggest that the proposed traffic redistribution mechanism and distributed policy adjustment algorithm can be used together to realize high-performance and reconfigurable bandwidth controllers.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125296317","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}

Thus, security mechanisms are proposed to protect communications. As one of most widely used security mechanisms, authentication is used to identify mobile nodes, prevent unauthorized usage, and negotiate credentials. Unfortunately, authentication mechanisms have been proposed up to now are impertinent in case of a mobile node has a high velocity or is in the ping-pong effect. In this paper, we propose a dual authentication scheme using Identity-Based Encryption. Using this scheme, a mobile node employs a dual authentication policy so that it reduces the fault rate of authentication up to about 57.1% based on the same network parameters and solves the ping-pong effect. Numerical results presented in this paper shows that our scheme has superior performance comparing to the standard AAA architecture.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122756601","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}
