This paper presents an evaluation of the Multi-RTCP Scheme over hybrid networks composed of wireless and fixed networks. We examined a rate- adaptive sending method for RTP packets based on detailed application-level QoS information on the hybrid network. The QoS information which includes each portion of the hybrid network is reported by the Multi-RTCP scheme. We present several advantages of the adaptive sending method using the Multi-RTCP scheme. Our experiments reveal network quality of service and perceived speech quality in practical conditions of the hybrid networks.","PeriodicalId":194551,"journal":{"name":"CCNC 2006. 2006 3rd IEEE Consumer Communications and Networking Conference, 2006.","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133201597","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 proposal supports two protocol variants. First, the fast handoff process, which anticipates the LSP procedure setup with an adjacent neighbor subnet that an mobile node (MN) is likely to visit, is provided to reduce service disruption by using the link-layer (L2) functionalities. Second, a new mechanism based on the forwarding chain concept is proposed to track efficiently the host mobility within a domain. This concept can significantly reduce the registration updates cost and provide low handoff latency. New analytical models, which capture the mobility behavior of an MN, are developed for cost analysis. Numerical and simulation results are given to justify the benefits of our proposed mechanisms.","PeriodicalId":194551,"journal":{"name":"CCNC 2006. 2006 3rd IEEE Consumer Communications and Networking Conference, 2006.","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131953067","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}

P2P content sharing services gather attentions because of their robustness. But they have some problems, such as low search precision ratio, significant increasing of traffic, and a lot of malicious content such as virus. To solve them, we propose a method in which a query is forwarded only to peers that have indices of content semantically similar to the desired one and not forwarded to the same peer repeatedly. To ensure high efficiency, this makes use of ideas of the CAN topology and a vector space method, whose vectors are variable lengths. The effectiveness of the proposal is shown both by analytical estimations and simulation experiments. 1.

Consumer communications services use this protocol to offer services such as remote control of home devices and interactive telecommunication services. Unlike existing digit collecting and matching protocols, the Key Press Stimulus Package is particularly suited for working in environments where multiple, unrelated applications receive user input from a single, mono-modal user interface device. We compare KPML to a representative, digit-bydigit signaling protocol, DTMFAD. By reducing the number of protocol messages by only reporting complete digit string matches and by only sending strings to applications that are interested in the pattern, the Key Press Stimulus Package provides a substantial savings in network and compute resources.","PeriodicalId":194551,"journal":{"name":"CCNC 2006. 2006 3rd IEEE Consumer Communications and Networking Conference, 2006.","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127728276","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}

Gossip-based approach has the advantage that it is resilient to arbitrary node movements and failures. However, a large amount of data traffic will be generated by the gossip procedure. In this paper, an efficient tree-based reliable multicast protocol is presented. The proposed method can avoid feedback implosion at the source and share the workload of packet recovery among the multicast members. Simulations reveal that the large volume of data traffic in the gossip-based method will congest the network and adversely affects the packet delivery ratio. Tree-based method on the other hand is much more efficient and can achieve very good reliability. I.

In this paper we extend their analysis to calculate the maximum number of VoFi calls when two-hop forwarding is used in order to avoid rate adaptation at nodes with reduced received signal strength. We calculate this number for different combinations of data rates for slow node transmissions and potential two-hop transmissions. These calculations demonstrate that the use of two-hop forwarding increases the maximum number of VoIP calls in a multi-rate 802.11b network. We validate the analysis by means of simulation of G711 codec sources in a 802.11b network. Even though the earlier discussions focus on specific combinations of high data rate two-hop and low data rate one-hop transmissions in an 802.11b network, we conclude the paper by calculating the maximum number of VoIP calls that can be supported with uniform node distri- bution in 802.11b and 802.11g networks. These calculations show a significant increase in the number of VoIP calls when two-hop forwarding is used in an 802.11g network. This sig- nificant increase is due to the higher data rates and the low PHY overhead of the 802.11g MAC.","PeriodicalId":194551,"journal":{"name":"CCNC 2006. 2006 3rd IEEE Consumer Communications and Networking Conference, 2006.","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121331796","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 implement the proto-type file system on ARM9 embedded platform. In experiments, MNFS exhibits uniform I/O latency for sequential write operation. It is mountable within 0.2 seconds, and available with only 34Kbytes heap memory for 128Mbytes volume.

Unfortunately, previous studies lack realistic modeling of vehicle mobility and evaluation of clustering performance so they may not correlate well with performance in a real deployment.
