| Popis: | 98 The provision of anytime anywhere communication is an essential issue for many network applications. The rapid advance development in information and communication technologies has made mobile users access service more efficiently and conveniently. This thesis investigates the routing issue in different applications in ubiquitous computing. Mobile users face very different routing issues in different ubiquitous environment. For example, when driving on the road, mobile users are more interested on connecting to a nearby information provider to retrieve environmental context information or looking for travel planning information. On the other hand, in a high speed rail train where connecting to the Internet is usually unavailable from mobile devices, mobile devices are more appropriate to communicate over mobile ad hoc network (MANET) and mobile users are more interested in sharing resources, such as newspaper, video files and music files, over a P2P overlay. Therefore, this thesis studies the routing issue in ubiquitous networks from following three perspectives: 1) context aware routing, 2) anycast routing and 3) P2P routing. Context aware routing focuses on designing a human-centric, context-aware and intelligent path planning service while satisfying individual user requirements. Anycast routing focuses on designing a anycast routing protocol based on swarm intelligent to help a mobile device to find a short path to a neighboring server quickly and efficiently. P2P routing mechanism deploys a P2P system on MANET to maintain the overlay connectivity and share information. P2P routing focuses on designing a scalable, self-organizing, self-addressing, self-routing and location-aware peer-to-peer system to allow mobile nodes form an MANET flexibly and share information easily and efficiently. Simulations are conducted to show high data rate, low overhead, efficient, and autonomous of the proposed context-aware, anycast and P2P routing mechanisms. The main contribution of this thesis is to propose routing mechanisms which provide mobile users wireless connectivity and apt applications at anytime anywhere in ubiquitous networks. |
