A number of trust routing protocols proposed restrict at standard routing protocols, therefore, lack accuracy in routing selection and rationality at trust evaluation. In this paper, a novel trust routing decision algorithm based on fuzzy dynamic programming theory has been proposed, which, to the best of our knowledge, is the first such solution proposed. Moreover, we have also proposed a model for trust evaluation and trust update that can be used with our trusted routing protocol. The model is different from other schemes in that it tries to analyze the physical requirements and psychology of the malicious attackers. Extensive simulation has been carried out on verifying the performance of our protocol.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125502641","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}

With this in mind, we propose a new routing scheme called adaptive multiple copy multiple hop algorithm (AMM). By collecting the simple information about the status of the network, AMM dynamically adjusts the number of message copies and forwarding conditions in the process of message delivery. Furthermore, AMM takes use of the stability of the network topology during a short period of time in some local area, and establishes group connected domain to help data transmission. The simulation results show that AMM achieves a good performance on delivery delay, and reduces the network load and the energy consumption in guarantee of certain delivery rate.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122802783","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}

Partial encryption and other media encryption schemes are effective approaches to encrypt those data. However, a partial disclosure of media data can leak the secret about the conference, moreover when wireless terminals joint in those systems, the limited wireless bandwidth and computational capability will lead to new security challenges. To solve those problems, a novel security scheme for video conference system with wireless terminals is proposed, which integrates three key modules seamlessly: 1) wireless access gateway based on adaptive selective forwarding; 2) dynamic optimal selective control mechanism for securing multi-data stream in the system; 3) a novel lightweight fast media data encryption algorithm. A prototype has been implemented in an actual video conferencing system: Admire. Experimental results show the efficiency of the scheme is suitable for real-time applications.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133494141","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}

Due to the characteristic of array codes such as STAR codes, the computation in secret sharing scheme need only XOR operation on GF(2), which is distinguished with the modulation and other complex operation on GF(q) in the traditional schemes. Thus, it's more rapid and suitable for large capacity secret sharing, and also appropriate for resource constrained environments, such as embedded systems. The process of distribution and reconstruction of the secret key in our scheme is depicted in details, and an example of (5, 8) threshold secret sharing scheme based on (8, 5, 4) STAR code is demonstrated. Our scheme is proved to be perfect and ideal.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"318 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134525498","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}

Based on the prototype experiment, several centralized and decentralized algorithms for location policy were examined on simulations, and the methodology to control code migration to have suitable response time in the system is derived.

Current protocols we used usually maintain a O(logN) route table and O(logN) routing hops. To get better routing speed with less scale routing table, using O(1) node finger to get O(N) route path, a new protocol named CSSP was presented. A short routing table was made to record ldquoLrdquo cache nodes, one super node and one successor node. Algorithms for maintaining the route table was presented in this paper. A selection algorithm was presented to select the super node who could cache all of the nodes. And the cache-nodes, super-node and successor-node ensure the high performance of the CSSP. Compared to chord, pastry and etc., the CSSP increases the performance in routing table maintaining, routing hops, fault-tolerance and the amount of churning nodes while some nodes inject and eject the CSSP p2p system. The simulations and analysis shows that the CSSP is an efficient route algorithm, but also some problems waiting for further study.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129674181","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}

Previous works on layout extraction mainly concentrated on how to find out the type of devices and connections between them, few works has addressed the information of centerlines and widths of IC interconnects in a polygon-based VLSI layout, which are required in inductance calculation and other applications. In this paper, an efficient scheme for the centerline-based path recognition from an IC mask layout is presented. Unlike the division-based methods, a tree-traverse-based approach is proposed. This new scheme can be realized as a reverse procedure of the layout generation from wire routing trees. Moreover, this scheme can handle complex all-angle wires. Experimental results show that this scheme has nearly linear computational complexity yet generates precise results.","PeriodicalId":231129,"journal":{"name":"2008 Fifth IEEE International Symposium on Embedded Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116418098","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}
