With mobile WiMAX deployments increasing, many expect fierce competition between 3GPP and WiMAX Forum mobile broadband technologies. We take a different approach in this paper and study cooperative multiaccess in an urban scenario, where mobile WiMAX and 3G cellular are used in a complemen- tary manner to deliver mobile video services. We position our work with respect to a novel information-centric approach in networking and evaluate through simulation the benefits arising from better management of multiaccess device capabilities in WMAN multimedia content distribution. In particular for the scenario we examine, we find that tapping on unused resources from different WMANs allows for significant increase in service delivery rates. Our results show that there is a lot to be gained by following a cooperative, rather than an antagonistic approach. I. INTRODUCTION Mobile and wireless multiaccess is a topic that has received significant attention lately. The availability of multiaccess devices is growing fast and, soon, devices that bundle cellular and wireless LAN (WLAN) network interfaces will be com- monplace. Meanwhile, urban areas are likely to be blanketed by overlapping broadband wireless access networks. Cur- rently, proprietary and non-IEEE standardized wireless MANs (WMANs) are available in some countries, and 3G/UMTS is the dominant mobile broadband technology. Country-wide mobile WiMAX and LTE deployments are expected in the coming years. In short, we anticipate that in the near future multiaccess mobile nodes will be able to access overlapping mobile WMANs, 3GPP cellular networks, and WLANs.","PeriodicalId":271067,"journal":{"name":"2009 IEEE International Conference on Communications Workshops","volume":"87 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130888996","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 paper evaluates the performance of different coordinated multi-cell transmission methods with several channel allocation algorithms in different scenarios with varying inter- cell interference. A generalised method for joint design of linear transceivers with coordinated multi-cell processing subject to per-BS power constraints is provided for single antenna receivers. The method can accommodate a variety of scenarios from coherent multi-cell beamforming across a large virtual multiantenna broadcast channel to single-cell beamforming with inter-cell interference coordination and channel allocation. The system optimisation objectives are weighted SINR maximisation across all the transmitted data streams and weighted sum rate maximisation. The numerical examples demonstrate the value of the coherent multi-cell beamforming, which greatly outperforms the non-coherent cases especially at the cell edge. The coordinated single-cell transmission with interference avoidance and dynamic user allocation is also shown to perform relatively well with a partial spatial loading.","PeriodicalId":271067,"journal":{"name":"2009 IEEE International Conference on Communications Workshops","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124063235","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}

Video surveillance cameras are currently becoming important tools for the public safety agencies. Enhanced CCTV surveillance systems can automatically spot suspicious behaviour and raise an alarm. The CCTV application is one of the key challenging services under the future Public Safety Communication Systems (PSC) and Technologies scope. Deploying this application in uplink stream in the transport public scenario represents great technical challenge and research effort. This article presents a simulation performance analysis on CCTV deployment as an Ethernet service over the WiMAX Mobile Network in a train scenario. The CCTV traffic is characterized; the Key Performance Indicators (KPI) according to WiMAX Profile 1.5 and the Public Safety requirements are also identified. The WiMAX network, and consequently the IEEE802.16 opportunity for attending this type of public safety applications, is highlighted. The current IEEE 802.16m specification covers the high mobility classes and scenarios supported by the IMT-Advanced. This IEEE802.16 new release will also be able to support public safety first responders, military and emergency with services such as callprioritization, pre-emption, and push-to-talk. Finally, the simulation analysis verifies that the CCTV KPI specified values are met at different mobile speeds.
