However, how to distribute the high-quality video streams that are already delivered to the doorsteps of ordinary customers to almost all rooms in their dwellings still remains a technique challenge. There are various proposals for wired, ``no-new-wires\" or wireless approaches, but their performance in real environment is yet to be examined. In this paper, we evaluate the performance of high-quality video streaming over short-range wireless networks, specifically Ultra-Wide Band (UWB), for a two-tiered broadband home network. Our analysis and experiment results reveal the unique features of UWB reservation schemes and their intrinsic throughput-latency tradeoffs, which indicates the efficacy of UWB for high-speed, in-room wireless access with both quality and mobility provisioning.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123684387","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}

There has been a number of proposed ideas to solve this issue. The existing approaches use techniques that either employ limited user navigation modes or do not perform satisfactorily for interactive applications. In this paper, we propose a new protocol that offers the user a richer navigation by pre-streaming the necessary imagery data to generate new views as the user wanders within the 3D environment. We introduce the idea of key partial panoramas, i.e., panorama segments that cover movements in any direction by simply strafing from an appropriate key partial panorama and streaming the amount of lost pixels. We have implemented our ideas and evaluated it against two well-known approaches. Experimental results show that our solution outperforms the selected approaches by minimizing the delay between image updates and by allowing a more complex navigation scheme than previous works.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130210059","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}

Data partitioning is one of the very important error resilience features of H.264. With data partitioning, each video slice is encoded into three different units of data with different importance. The encoded partitions containing the most important information should be protected against transmission error to ensure good picture quality. By virtue of multistreaming and partial reliability property of Stream Control Transmission Protocol (SCTP), we can set different priority or reliability levels for different data partitions. In this article, we investigate the impact of the loss of different partitions on picture quality. We present a comparative study of the possible solutions for transmission of H.264 video using SCTP, considering both partitioned and non-partitioned H.264 video. We demonstrate how reliability features of SCTP can be efficiently mapped to the error resiliency features of H.264 video.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"883 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130710425","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 tackle this issue we suggest minor extensions in the SIP protocol as well as the use of middleware to allow calling users to dynamically select the best way to route their requests towards called users.

In wired networks, multicast stream merging is a well-known technique for scalable on-demand streaming. Also, caching proxies are widely used on the Internet to offload servers and reduce network traffic. This paper uses simulation to examine a caching hierarchy for wireless streaming video distribution, in combination with multicast stream merging. The main purpose is to gain insight into the filtering effects caused by caching and merging. Using request frequencies, entropy, and inter-reference times as metrics, we illustrate how merging, caching, and traffic aggregation affect the traffic characteristics at each level. The simulation results provide useful insights into caching performance in a video streaming hierarchy.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116284800","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 get more bandwidth, multipath routing is one appropriate solution provided that inter-path interferences are minimized. In this paper, we address the problem of interfering paths in the context of wireless multimedia sensor networks and consider both intra-session as well as inter-session interferences. Our main objective is to provide necessary bandwidth to multimedia applications through non-interfering paths while increasing the network lifetime. To do so, we adopt an incremental approach where for a given session, only one path is built at once. Additional paths are built when requi red, typically in case of congestion or bandwidth shortage. Interference awareness and energy saving are achieved by switching a subset of sensor nodes in a passive state in which they do not take part in the routing process. Despite the routing overhead introduced by the incremental approach we adopt, our simulations show that this can be compensated by the overall achieved throughput and the amount of consumed energy per correctly received packet especially for relatively long sessions such as multimedia ones. This is mainly due to the fact that a small number of non-interfering paths allows for better performances than a large number of interfering ones.","PeriodicalId":131891,"journal":{"name":"Wireless Multimedia Networking and Performance Modeling","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131015036","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 resource limitations of wireless clients, it is a challenge to select an appropriate service, which is suitable for wireless devices based on their respective QoS demands. To overcome this challenge, we propose a novel QoS-aware multimedia service selection framework, which inherits the adoption of nature-inspired path selection behavior in the service selection. We extend the nature-inspired algorithm to support QoS for multimedia service selection.
