Abstract
As the demand for “anytime, anywhere and anyway” communications increases, heterogeneous network design trends will grow faster supporting user affordable and transparent device technologies.
The Internet, a network of networks, most popularly called “network of things” has been playing significant ro le in changing a person’s lifestyle with services ranging from shopping, finding local entertainment to helping children with homework. The future global communication network will be all IP-based supporting heterogeneous core and access technologies for broadband, fixed and mobile services. To meet future applications such as multicast, media streaming, content delivery distribution, and broadband access new communications infrastructure that offers greater bandwidths and service level guarantees is required. Satellite communication plays a significant role in supporting such architectures through hybrid Satellite/Wired/Wireless infrastructure due to its main characteristics of ubiquitous coverage, bandwidth flexibility, and multipoint-to multipoint connectivity. This presentation will address various satellite networking architectures , with current system examples and trends for future network systems deployment. For example a hybrid communication network model could consist of personal (Body /Area), local and home (W -LAN, UWB), cellular (GSM, GPRS, UMTS) and wide area (DVB-S/S2/RCS, and BWA) networks to provide global communications. This presentation will include the technical challenges e.g. bandwidth allocation, DAMA, end-to-end Quality of Service (QoS), TCP enhancements, and cross-layer design approaches and a discussion of technology solutions. A brief status on the standardization activities from ITU, ETSI, TIA and IETFwill be provided. The cross layer design methodologies for improved QoS will be de tailed through simulation examples for “net centric” hybrid network e.g. SATCOM/ WiMAX and fading effects on multimedia QoS. The presentation concludes with a few thoughts on social implications of satellite/ wireless pervasive communications on a fast growing “personalized creative” society.
