However, each Mesh Subscriber Station (MSS) transmits its own traffic and forwards the traffic of its children while each traffic flow has its particular QoS constraints. As all forwarded traffics use the same link, one MSS may experience starvation or act selfishly. Besides, the MSS's mobility adds important complexity as all the affected flows need to be re-routed, re-admitted and re-scheduled while respecting their original QoS requirements. In this paper, we adopt the concept of assigning five virtual nodes to each MSS reflecting the five QoS classes of IEEE 802.16e and we propose scheduling the uplink transmissions of the real-time Polling Service (rtPS) traffic class by adopting the Genetic Algorithms concept. We define the priority assigner component which communicates with the scheduler of the mesh BS in order to set and update flows' priority and we optimize the time spent by a flow in the queue while implementing the mobility constraints within the mutation function.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114626145","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 desirable to have an automated adaptation of the behavior of a mobile device depending on a change of user context to fulfill expectations towards practical usefulness. To enable mobile devices to adapt their behavior automatically there is a need to determine the mobile user's context. In this paper we introduce an integrated approach for the automatic detection of a user's context. Therefore, we summarize and discuss existing approaches and technologies and describe a service architecture that takes into account information from the interaction of the mobile device with communication networks and positioning systems, from integrated sensors, and planned behavior of the user from e.g his calendar or activity list. Additionally it considers the social network of the user to derive further information about his context and finally it takes into account his customs through a behavior model.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114747527","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}

Besides Wi-Fi, FSO plays a very relevant technological role in this context. Performance is essential, resulting in more reliable and efficient communications. A FSO medium range link has been successfully implemented for high requirement applications at Gbps. An experimental performance evaluation of this link has been carried out at OSI layers 1, 4 and 7, through a specifically planned field test arrangement. Several results are presented and discussed, as obtained from simultaneous measurements of powers received by the laser heads, TCP, UDP and FTP experiments, resulting in determinations of TCP throughput, jitter, percentage datagram loss and FTP transfer rate. Conclusions are drawn about link performance.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133526991","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}

Nonetheless, in existing schemes thereare still some deficiencies, such as the lake of flexibility, proportionality and adaptability. In this paper, we present a resource discovery model Mobile-Tapestry (M-Tapestry) for mobile P2P networks based on the P2P Tapestry strategy. The philosophy of this model is to make the network architecture layered, and only a small number of super nodes are chosen instead of all nodes to access the Tapestry system. This measure may reduce the cost of ordinary nodes and solve the reliability problems caused, when the routing table is updated frequently. Additionally, we partition the nodes according to their geographical location, this may avoid the problem that the distance between the nodes having adjacent IDs is actually large due to the Hash operation. Finally, our simulation results and analysis shows that the M-Tapestry strategy has an improved lookup efficiency for mobile P2P networks compared to the Tapestry strategy.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"718 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128519","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}

Any serious attack at the routing layer can cause serious damages. Although a lot of security measures have been proposed for application and transport layer, we have found that there is not enough research geared towards securing the network at the routing layer. In this paper, we propose a novel solution for securing against external as well as internal attacks. The protocol maintains a working network by using redundant multiple paths despite attacks at one route. It also identifies and removes the malicious nodes from the system. Since the system is totally distributed and does not require a central server as required in some of the other protocols, there is no single point of failure. We also keep in mind the limited computing resources and network bandwidth of the wireless sensor nodes. Finally the paper quantifies the protocol's effectiveness against some of the existing secure routing protocols namely QDV and SNEP using simulation studies.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124804885","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 solve the decision problem, in the case that multiple licenses refer to the same content, OMA suggests a license choice algorithm. This algorithm ensures the fine grained consumption of contents. CafeOBJ is a new generation algebraic specification language. We apply the OTS/CafeOBJ method to formally model, specify and verify the above mentioned license choice algorithm. More specifically, we develop the mathematical model of the OMA decision algorithm as an OTS, a kind of transition system expressed in an equational CafeOBJ specification style. Finally, we verify that this algorithm fulfills the following safety property: Whenever a license is chosen for a given content, then the license is valid at that specific time.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124279737","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 goal is to find features that enable reliable identification of like-model communication devices having different serial numbers. Once achieved, these unique physical layer identities can be used to augment existing bit-level protection mechanisms and overall network security is improved. ANOVA experimentation is generated using a subset of collected signal characteristics (amplitude, phase, frequency, signal-to-noise ratio, etc.) and post-collection processing parameters (bandwidth, fingerprint regions, statistical features, etc.). The ANOVA input is percent correct device classification as obtained from MDA/ML discrimination using three like-model devices from a given manufacturer. Full factorial design experiments and ANOVA are used to determine the significance of individual parameters, and interactions thereof, in achieving higher percentages of correct classification. ANOVA is shown to be well-suited for the task and reveals parametric interactions that are otherwise unobservable using conventional graphical and tabular data representations.","PeriodicalId":332730,"journal":{"name":"2010 International Conference on Wireless Information Networks and Systems (WINSYS)","volume":"22 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128830518","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}
