To achieve agile and cost effective telecom operations, it is important to have well-defined operational workflows for each operational process. However, defining ultimately-optimized workflows for all operations in-advance is unlikely since new services are frequently created and the relevant infrastructure is renovated on a daily basis. Modifying the predefined workflow often in line with environmental changes incurs considerable operational costs, since manual operation is required to keep all workflows up-to-date. Accordingly, a mechanism to generate workflows automatically is necessary to swiftly and economically adapt to the dynamic environment. In this paper, automatic tagging technology to generate discrete operation records and quantitative evaluation-based workflow trimming technology to extract operational workflows from stored operation records are developed to map operating processes to the business process model. Throughout the scenario demonstrated, an efficiency to analyze actual operations and the capability of generating operational workflows are indicated.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115228971","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 propose a mathematical model which adjusts the radius of base station, to figure out the problem of energy saving, while the quality of services such as the traffic volume of each base station and the service area should be satisfied. For the model, we use ant colony algorithm as a practical method to solve this problem. By using this mechanism, we can achieve the purpose of energy saving, when the traffic in a service area is low.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116938297","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 analysis phase, UML is used as the modeling language to present technology independent models, and these models can be mapped into multiple technology specific models. With the development of Web Services applied in network management domain, it is required to define Web Services-based information models in design phase. This paper applied MDA approach to realize models transformation. As the main work, this paper proposed detailed mapping rules describing how to map the existing source UML models into the target Web Services-based models. An automatic transformation approach using XSLT was proposed to implement the mapping rules, and experiments were made for verification. The proposed mapping rules improved the defects in related work. Furthermore, the work of this paper could help resolve some issues in current models transformation work which is still being accomplished manually by standard developers.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125902483","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 assume Secondary Users (SUs) can choose to either acquire a dedicated spectrum with constant payment or to use a Primary User (PU) band for free. However, using PU band yields delayed transmission cost. In this paper, we apply M/M/1 queueing model with heterogeneous service rate to derive the explicit expressions for the expected delays of an arbitrary SU data packets. Based on this, the SUs need to decide whether to use the Primary User (PU) band or to acquire the dedicated band. The interaction between selfish SUs is modeled as a noncooperative game. We prove the existence and uniqueness of a symmetric Nash equilibrium, and characterize the equilibrium behavior explicitly. Then an appropriate price of the dedicated band can be defined. Numerical analysis are used to prove a high degree of accuracy for the derived expressions.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122089368","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}

Healthcare is one of the areas on which M2M is going to play major roles. At present time, healthcare sensors monitor patient information and notify remote doctors. However, if we can integrate more intelligence in healthcare sensors, then these can sense patient's emergency condition by themselves and can notify doctor before severe condition. In this context, we have developed intelligent mobile sensor agents in a healthcare scenario in a M2M context. This sensor agent can sense blood pressure of a patient and can notify remote doctor, with the help of an intelligent adapter and a manager in a M2M healthcare scenario.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127612019","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, VMs often have inherent dependencies which bring complex load interactions among the underlying physical servers. Unreasonable migration will lead to a decline in network performance. In this paper, aiming at energy saving, we propose an application-aware policy in VM consolidation process. Moreover, in order to guarantee that the migrated VMs can be efficiently placed on physical servers determined by the application-aware policy, we also propose a multi-dimensional resource allocation algorithm (MDRA). Experiment results show that the proposed application-aware policy can efficiently reduce energy consumption as well as improving network performance. And the proposed MDRA algorithm can ensure the effectiveness of our policy.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115910147","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 the relay architecture, the header compression mechanism called RObust Header Compression (ROHC) is introduced to eliminate packet overhead and provide better spectral efficiency for IP packet transmission over the radio. However, the ROHC mechanism specified in the relay architecture causes huge computation load. This paper proposes an efficient ROHC mechanism to improve the header compression performance in the relay architecture. A modeling study is performed to tune the parameters defined in the proposed mechanism to yield better performance. Our study suggests an efficient ROHC mechanism that decreases over 30% header computation load in comparison with the mechanism defined in the specification.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127845492","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}

It is hard to reproduce these kinds of leaks, let alone to identify and fix them early in the development phase. Thus online memory leak detection is required. In this paper we propose a two-phase approach to the online memory leak detection problem for Java programs. In phase one (offline analysis), the user executes the investigated program for a while and analyzes its heap with the proposed agent. The agent then summarizes the total occupied bytes of data structures in the heap offline, and the user is then able to select classes whose object instances seem to be potential leaks by examining the total occupied bytes summary. In phase two (online monitoring), to reduce the space and time overhead at runtime, the agent monitors online the objects of selected classes instead of monitoring all objects in the heap. The approach reports the last accessed time and location (including the source file name and the line number) of each leak candidate, with which the user can identify and fix leaks in the program.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129529910","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 a Cloud environment, different types of resources need to be virtualized as a collection of Cloud services using virtualization technology. End-users in the Cloud are usually provided with customized Cloud services that involve not only different kinds of computing services but also the networks interconnecting those computing services. Therefore, a set of Cloud computing services and the networking services should be modeled as a composite customized Cloud service. In this paper, we present an improved model for Cloud service provisioning based on our previous Network-Cloud proposal, and propose a procedure with several QoS-aware service selection algorithms for composing different services offered by a Cloud. Our analysis with numerical experiments show that the presented algorithms can select services appropriately that deal with different requirements of service provisioning.","PeriodicalId":385920,"journal":{"name":"2012 14th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130816077","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 can provide user-centric context-aware services by aggregating and associating the diverse types of context data distributed over multiple domains around a user. However, state-of-the-art research efforts have been devoted to managing context only in a single domain.
