| Summary: | 碩士 === 逢甲大學 === 資訊工程所 === 93 === In mobile ad-hoc networks, anycast technology can be used to find the nearest service through the anycast address. Although some anycast schemes have been designed and developed for mobile ad-hoc networks, most of these schemes have only been simulated but not practically implemented on real mobile ad-hoc networks. As far as we know, there is no implementation of anycast system on IPv6 based mobile ad-hoc networks. As the network technology developed, the range of addresses of IPv4 is not enough to use. Due to the trend of IPv6, this work designs and implements an anycast scheme on IPv6 based mobile ad-hoc networks. The implementation of the system is a cruel testing of the system because it can reflect the reality of the system. In order to resolve the vibrated route of the connection oriented anycast service, the anycast address mapper should be integrated into our scheme. If the anycast service is provided in mobile ad-hoc networks, there may cause a lot of traffic. Although a distributed clustering scheme can be used to manage such kind of traffic, structures of control messages and related data flow may need to be refined and modified to adapt to the features of IPv6. Our system is implemented on the Linux platform and it can be run in the real mobile ad-hoc networks. Experiments are conducted on the real networks to get the reality of our system. Experimental results demonstrate that our anycast schemes can resolve the anycast address via anycast address mapper and these schemes can operate correctly under IPv6 mobile ad-hoc networks.
