However, packet level interleaving has the ability to cope with lengthy bursts of error on a wireless channel. This paper proposes adapting the degree of packet interleaving according to: the display deadlines of packets; transmit buffer occupation; and anticipated video input to the wireless channel. Conservative adaptation is applied to avoid missed deadlines and the picture type importance is taken into account. A detailed Bluetooth case study illustrates the value of the techniques and as a by-product the paper corrects some erroneous results of others for Bluetooth version 2's Enhanced Data Rate.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130327751","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 approach not only lacks sufficient scalability and efficiency of delivery, but also poses a heavy burden on the home network and the global Internet. In this paper we propose a new decentralized mobility management service (DMMS) architecture to address this issue. The idea is to employ a local mobility agent in each access network, which handles node mobility based on local movement information, so that the on going communication can be maintained efficiently and scalable without relying on centralized traffic distributing entities.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129868440","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}

Olariu","doi":"10.1145/1298216.1298217","DOIUrl":"https://doi.org/10.1145/1298216.1298217","url":null,"abstract":"In the past decade, Vehicular Ad Hoc Networks (VANET), that specialize Mobile Ad Hoc Networks (MANET), to vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications have received a great deal of attention in the research community. And with a good reason: vehicular communications promise to integrate driving into a ubiquitous and pervasive network that is already redefining the way we live and work. The potential societal impact of VANET was confirmed by the proliferation of consortia and initiatives involving car manufacturers, government agencies and academia including, among others, the Car-2-Car Communication Consortium, the Vehicle Safety Consortium, the Networks-on-Wheels Project, the Vehicle Infrastructure Integration Program, and the Advanced Safety Vehicle Program. While the original impetus for VANET was traffic safety, more recent concerns involve privacy and security. It was recently noticed that allocation of 75MHz spectrum in the 5.9GHz band for Dedicate Short Range Communications (DSRC) in North America opens VANET to multimedia applications including peer-to-peer (P2P) content provisioning and the fast-growing mobile infotainment industry. In spite of their close resemblance to MANET, with which they share the same underlying philosophy, VANET networks have a number of specific characteristics that set them apart from MANET. The presentation will discuss the state of the art in VANETs as well as a zero-infrastructure for multimedia over peer to peer for VANET.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129104297","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}

As finding a near-optimal adaptive transmission schedule, in our case for the prioritized access categories of the 802.11e Enhanced Distributed Channel Access (EDCA), is a combinatorial optimization problem, we introduce an Ant Colony Optimization (ACO) based meta heuristic for scheduling multimedia traffic. ACO is known to develop near-optimal solutions at the expenses of additional administrative and computational overhead. We compare ACO scheduling to a deterministic scheduling approach specifically designed for the needs of multimedia scheduling called MLLF. The aim of this paper is to evaluate the feasibility of ACO approaches for multimedia scheduling in different scenarios and to conclude on the effectiveness of the selected deterministic MLLF approach in comparison to a near-optimal solution.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114597243","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, due to the best-effort character of the Internet and the limited resources available in wireless systems, there are many new issues and trade-offs that require discussion. Among these issues, the smooth playback of multimedia streams is an important topic. In this paper, we present a smooth playback technique for progressive multimedia streams over the Internet with wireless connections. The proposed technique employs progressive encoding techniques for multimedia streams and uses a modified MoSync algorithm to synchronize the streams at different levels of quality. Experimental results show that this technique can offer a high QoS for wireless multimedia systems.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122730851","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}
