Baroudi","doi":"10.4108/ICST.AMBISYS2008.2895","DOIUrl":"https://doi.org/10.4108/ICST.AMBISYS2008.2895","url":null,"abstract":"Bypass-AODV, a local recovery protocol, is proposed to enhance the performance of AODV routing protocol by overcoming several inherited problems such as unnecessary error recovery invocations, newly non-optimal reconstructed routes, high packet drop ratios, and high routing overheads. Bypass-AODV uses cross-layer MAC-notification to identify mobility-related link break, and then setup a bypass between the broken-link end nodes via an alternative node while keeps on the rest of the route. Therefore, Bypass-AODV enhances resource utilization by avoiding unnecessary error recovery cycles and consequently increases the network throughput. On the other hand, Bypass-AODV enhances route reliability; it avoids dropping packets by transmitting them over the constructed bypass. The simulation results show that when running 1-TCP connection, Bypass-AODV performs better than AODV. In particular, this behavior is rapidly changed with increasing the physical distance between the TCP connection end nodes beyond 2 hops. For example, when number of hops is equal to 6, goodput is enhanced by more than 100% compared to AODV for a 1-TCP connection and about 24% for multiple TCP connections. Further, the ratio of packet drop is reduced from 16% to 2%. Moreover, considering the hop count, the Bypass-AODV shows less sensitivity to the ongoing number of TCP connections.","PeriodicalId":217269,"journal":{"name":"International ICST Conference on Ambient Media and Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121022074","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 the IP Multimedia Subsystem (IMS) defined by the 3rd Generation Partnership Projects (3GPP and 3GPP2) represents today a basis framework that enables the vision of providing triple play services with quality of service and mobility support across heterogeneous networks. The Fraunhofer Institute FOKUS has recently launched the FOKUS Media Interoperability Lab (MIL) that is based on the \"Open IMS Playground\" testbed. MIL is as an open environment gathering all major IMS core components, and triple play toolkit originating from own developments as well as major industry players, which can be used by academic and industrial partners for early prototyping of new triple play services, related components, protocols, and applications. This paper introduces the relevant technologies and provides an overview of the testbed architecture and the relevant multimedia services at FOKUS. The validation of this architecture is demonstrated with an implementation in the testbed.","PeriodicalId":217269,"journal":{"name":"International ICST Conference on Ambient Media and Systems","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123954909","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}

This is especially true for continuous media (audio and video clips) because they are large in size and are streamed at a pre-specified rate to support a display free from disruptions and delays. Caching of clips across devices is an effective way to improve key quality of service (QoS) metrics including the fraction of requests serviced successfully when the home's connection to the outside infrastructure is lost (data availability), number of devices that may stream and display their referenced clips simultaneously (throughput), and the average delay incurred from when a user references a clip to the onset of its display (average startup latency). In this paper, we focus on home networks consisting of a handful of devices and present a novel cooperative caching technique named Cont-Coop. Cont-Coop controls the content of participating caches based on the asymmetric bandwidth of wireless connections between devices. We compare this technique with an alternative that does not control the content of cooperative caches, showing Cont-Coop is superior when the access pattern to clips is skewed. In addition, we show cooperative techniques enhance all the aforementioned QoS metrics when compared with a greedy caching technique.","PeriodicalId":217269,"journal":{"name":"International ICST Conference on Ambient Media and Systems","volume":"468 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116185659","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 main purpose of this research is to develop an efficient telemetry system for measuring water pressure and temperature signals. The system reads data from two types of sensors, resistive and capacitive. Anderson circuit configuration has been used for the resistive sensor, since it offers linear like behavior. The capacitive interface is based on capacitance-frequency-voltage conversion that uses phase lock loop (PLL) to convert the frequency to voltage. A developed pressure sensors based on polyvinylidene fluoride (PVDF) was used to evaluate the performance of the capacitive interface. Two mechanisms have been adopted to reduce the overall power consumption. These are power scheduling and wakeup circuit for the capacitive interface. The first one is implemented fully by the micro-controller unit (MCU) in order to switch on/off all the system units. A wakeup circuit has been designed to interrupt the MCU when it is in the sleep mode and the capacitive samples are changing significantly. A platform for wireless sensor network (WSN) has been developed so that the receiver side can communicate with more than one sensor node.","PeriodicalId":217269,"journal":{"name":"International ICST Conference on Ambient Media and Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131187797","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}
