The first step in the detection and tracking procedures is edge detection. Most of the edge detection schemes proposed for sensor networks require information on sensor locations. Also, quantitative measures by which performance of an edge detector for sensor networks can be analyzed have not been available. In this paper, edge detectors which do not require the absolute or relative location of each sensor node are proposed along with a set of metrics used for performance analysis. Detailed performance analysis results obtained through simulation, varying parameters such as sensor density, communication range, and noise level, are provided.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130412364","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}

We are facing spam problems. Spam message is widely used for marketing e-Commerce. To block these spam messages, we use filtering or pricing systems. But these solutions raise other problems such as impediment in reception or availability caused by false positive or payment resistance. To solve these problems, we propose a grant model for filter of message detour in e- Business system which controls an unsolicited electronic message and prevents useful electronic message from being discarded. We designed and implemented the grant model for filter of message detour in e-Business system to enhance the usefulness and availability of electronic message. Tests of grant model for filter of message detour in e-Business system proved very successful in it's usability and efficiency.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116907433","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 most important issue in such heterogeneous environment is the always best connected (ABC) concept. It allows the best connectivity to services anywhere at anytime. For that, a seamless inter-system handover solution is needed. In our paper, we propose an intelligent solution, based on the context-awareness concept, ensuring service continuity and answering user requirements. We focus on the vertical handover decision issue. It performs whether and over which access network to hand over among those available. It uses advanced decision algorithms (for more efficiency and intelligence) and it is governed by handover policies as decision rules (for more flexibility and optimization).","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132441226","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, the protocol has the triangular routing problem. Although many routing optimization extension schemes in IPv6 networks can solve the problem, the delivery of routing optimization messages in the handoff period may incur long transmission delay and message loss, and therefore degrade the performance of routing optimization mechanisms. In addition, all schemes require all mobile nodes and their correspondent nodes to be involved in mobility management. A mobile node must inform its correspondent node of its roaming and its new location address. In this paper, we exploit the domain name system (DNS) to develop a mobility management system. Except granting the access to a new wireless link after roaming, the mobility management is transparent for a mobile node and its correspondent node. No routing optimization message is delivered.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133382864","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}

Our model can be regarded as a theoretical analysis for time cost of message transmission to sink node in an event-driven process in which Slotted ALOHA protocol is implemented. The first passage time Tn,lambda depends on the size n of activated nodes and their transmission rate lambda. Given n, we study the optimal lambda and give the approximation radic1n n/n, further more we give the estimate of the size n from the view point of sink node. So that we can adjust the transmission rate lambda to attain the optimal expected time cost Tmin (n). Numerical result indicates that given the size of active nodes n, the optimal time cost of the procedure increases nearly linearly with n increasing which implies that ALOHA protocol is efficient even in dense event-driven sensor networks.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133961310","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}

We developed a context aware framework to send information from wearable sensors or healthcare devices to healthcare service entities as a middleware to solve the interoperability problem among sensor makers and healthcare service providers.
