It is important for business process to construct a complex one with multi-dimensional QoS assurance. But there exist some problems, such as evaluation for QoS properties of service is not full-scale and the criteria is not clear, the weight for each QoS metric doesn't consider both subjective sensations and objective facts. In this paper we propose a model to provide multi-dimensional QoS support in service selection and replacement. We define a utility function as the evaluation standard, which aggregates all QoS metrics after normalizing their values. Then we use subjective-objective weight mode (SOWM) to set the weight of each QoS metric. Also we propose a heuristic algorithm on the multi-choice, Multi-dimension 0-1 knapsack problem (MMKP) using the rule-library. Finally we test the efficiency of the algorithm and the results prove it is predominant compared with other algorithms.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"202 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131652238","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, a fundamental underpinning of the success of these technologies resides in the quality of data that they can provide. Often the failure of a technology is attributed to its functionality when the real problem lies in the quality of data it uses and subsequently produces.

This new and promising paradigm allows a fast, easy and inexpensive network deployment. While much effort has been made to address issues at physical, data link, and network layers, little attention has been paid to the security aspect central to the realistic deployment of WMNs. This paper addresses security of WMNs and proposes ISA (identity-based security architecture) for WMNs. ISA eliminates the need for certificate-based public-key distribution indispensable in conventional PKI schemes. It provides a light weight network access protocol based on pairing and hash function. As to key revocation, it introduces a neighbor detection mechanism. The public key of a node is revoked if a certain threshold number of nodes accused the node. ISA also enables efficient network-wide key update via a single broadcast message.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116154577","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}

To maximize the wireless sensor networks lifetime after the sensor nodes deployment, dynamic power management (DPM) should be carefully taken into account in wireless sensor networks. The goal of DPM is to reduce power dissipation by putting the sensor node into different states. In this paper, a new method of DPM based on wavelet neural networks is proposed to conserve energy. There are two salient aspects to this approach. First, the next event's time which is a non-stationary series is predicted as accurate as possible by wavelet neural networks. Nodes in deeper sleep states consume lower energy while asleep, but incur a longer delay and higher energy cost to awaken. Second, the nodes state in which lie wireless sensor network should lie is decided through the predictable time associated with the threshold time, residual power. The simulation results show that the energy consumption is significantly reduced and the whole lifetime of the wireless sensor networks is greatly prolonged through the proposed method.","PeriodicalId":278518,"journal":{"name":"2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124952879","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}
