Instable wireless channel conditions cause frequent transmission delays and packet losses due to fading and interference. Therefore, this situation leads to the degraded quality of video streaming service. The IEEE 802.11 Working Group is currently working on a new standard called IEEE 802.11e to support quality of service in WLANs. Several schemes have been proposed in order to guarantee QoS; however, they are not adaptable to network conditions. Accordingly, they suffered video quality degradation due to buffer overflow or packet loss. In this paper, to raise the quality of video streaming service in WLANs, we propose a cross-layer architecture. Our cross-layer architecture provides a differentiated transmission mechanism for IEEE 802.11e EDCA based on the priority of MPEG-4 video frames and the mechanism adaptively controls the transmission rate by dropping the frames based on efficient bandwidth estimation. Through simulations, the proposed scheme is shown to be able to improve end-to-end quality for video streaming service in WLANs.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126601629","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 existing single-hop delay differentiation schedulers can not differentiate the contention delay suffered at multi-hop links, and whole delay differentiation accuracy is destroyed in the multi-hop wireless communications. MWTP marks packets with departing time at the upstream node to decide scheduling order at the downstream node. The marked departing time becomes a reference point of waiting time in the scheduling process. Analysis and simulation results support that MWTP guarantees more accurate delay differentiation than existing schedulers.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"47 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133784743","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, these approaches have their own problems for video delivery. To compensate their disadvantages, in this paper, we develop a hybrid VoD system model that uses a P2P paradigm coupled with video broadcasting and CDN-like approach for video delivery. In the proposed architecture, the video is first partitioned into two parts. The first part of the video is transmitted among customers, watching the video, in P2P manner while the second part of the video is broadcasted periodically by the central server. This content delivery strategy allows the workload of the system disperse over the network while customers can still guarantee to obtain the service without collapsing by the dynamic nature of P2P framework. In addition, it also takes a benefit from video broadcasting. Analytical model is developed to allow system designers better understanding of system dynamics and provide guidelines for the management of design resources and realization of VoD services based on this architecture.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"681 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116183653","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}

Therefore, we designed a protocol called SNSLP for both QoS request and feedback messages. SNSLP has a unified format for both and reduces the protocol complexity. SNSLP was implemented on the top of RTCP for both an experimental network with policy-based QoS control and a voice application called voiscape. In addition, an implementation method using routers without an SNSLP stack for policy-based routing is described and the result of implementation is reported.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116690042","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}

Various rate adaptation schemes that select optimal transmission rate according to the receivers' channel condition have been proposed. Among these protocols, Automatic Rate Fallback (ARF) is the one that is widely implemented in commercial devices due to its simplicity. However, it is well-known that the performance of ARF deteriorates when the wireless channel condition is unstable or many frame collisions occur. On the other hand, RBAR (Receiver Based Auto-Rate) that achieves the good performance is rarely used because it introduces extra control overhead. In this paper, we propose a novel rate adaptation scheme that performs well without control overhead. The key idea of our proposed scheme is that if a station successfully overhears a downlink transmission whose data rate is higher than its current rate, then it requests the AP to increase the data rate to overheard frame's transmission rate. We compare our scheme with previous rate adaptation schemes in terms of throughput performance via the simulation study. The performance results indicate that our scheme achieves better performance than RBAR.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116509975","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 scheme for Incremental deployment of XCP, In which XCP-TCP gateways seamlessly interconnect the XCP and TCP domains. The XCP-TCP gateway maps the congestion control functions between XCP and TCP.

The cognitive radio device is allowed to use the spectrum only when it does not cause any interferences or collisions to the incumbent users. We suggest an adaptive MAC protocol for the purpose of a throughput enhancement in cognitive radio networks. Assuming the channel status is dynamically known to the devices, they change their transmission mode between frame recovery mode and dual transmit mode according to the channel status. When the cognitive channel is hard to use due to frame errors, the channel is used for the frame errors recovery. Otherwise, in addition to its own legacy channel, the cognitive channel can be used to increase the throughput. In this paper, we study the effect of using additional channel in the cognitive networks, and prove an adaptive method of MAC protocol in the interest of throughput enhancement in cognitive radio network, and prove the performance of our proposed mechanism by simulations.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123575081","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}

Such mechanisms require the network to inspect the packet payload at line rates to filter the worms or virus. These signature sets are large and some signature can be as long as more than 2000 byte. This paper propose a high performance and scalable packet pattern-matching architecture. Bloom filter engines are used in front-end for membership query which can achieve high performance, and an lookup table is used in back-end to performance deterministic string-matching. In order to solve the scalability problem in using Bloom filter to detect long pattern, prefix register heap is used to keep the intermediate status. The architecture can achieve gigabytes throughput with large pattern set and long patterns. A great saving in hardware resource also proves that the architecture is very scalable.","PeriodicalId":447966,"journal":{"name":"2008 International Conference on Information Networking","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126445077","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}

Hence the ubiquitous computing community has recently studied about this problem and improved their solutions. One of their solutions is context- awareness.

To get the location information, we use Bluetooth because it has increasingly widely been deployed due to its low power consumption and cost. The system we created to get user's location is based on signal strength of Bluetooth. Therefore, using this information, this system re-routes the ongoing media streaming to the closest device where a user is, when the user is out of the range of a certain device.
