Video streaming for IPTV is transferring to wireless mobile devices. This process poses questions of the video quality that will result and the suitability of the existing pseudo-streaming schemes for video transfer. This paper sets out the case for wireless broadband video streaming based on a simple negative acknowledgment (NACK) scheme, which for convenience is called broadband video streaming...
One of the key targets for LTE/SAE is 100 Mbps peak data rate in downlink. While compared to the lined data rate, the wireless data rate is still a bottleneck. This means if there is no flow control in aGW; packets will be buffered in eNB. While the buffer in eNB is limited, packets may be dropped. To reduce the harm to the performance of the TCP based application from packet loss, flow control is...
The widespread use of heterogeneous wireless technologies and their integration with multi-mode terminals enable users get associated to the best available networks according to user preferences and application specific requirements. In this paper we present a user-centric network selection approach where negotiation between users and network operators is carried out using multi-attribute auctioning...
In future wireless networks, the users will have the capability to access to multiple networks via multi-mode terminal. There is a need to have mechanism in place to decide which radio access network is the most suitable for the user and for the services that the user requires. To address these issues, we propose an access system(AS) selection algorithm, based on a combination of multi-attribute utility...
The use of Broadband Wireless Access (BWA) technology is increasing due to the use of Internet and multimedia applications with strict requirements of end-to-end delay and jitter, through wireless devices. The IEEE 802.16 standard, which defines the physical (PHY) and the medium access control (MAC) layers, is one of the BWA standards. Its MAC layer is centralized basis, where the Base Station (BS)...
