Name resolution system for mobile ad hoc networks RANR (randomly-assigned name resolution)

摘要

Due to recent advancement in technology of wireless communication, use of small sized computers in a mobile environment has become possible. Mobile ad-hoc networks are temporarily constructed by mobile hosts without established infrastructure. Such networks can constitute a base for human cooperative works as well as for communications between information systems. However, there have not been sufficient work of name resolution systems suitable for ad-hoc networks. In this paper, we propose a name resolution system called RANR suitable for ad-hoc networks as a base technology for application construction environment. RANR can provide a node with a unique user-oriented names in an ad-hoc network, thereby adapting to dynamic changes of network identifier configuration. In addition, RANR relieves users and their applications from the necessity of identifying the network addresses (IP addresses) of nodes by introducing unique names as employed in DNS. We have designed and implemented RANR in FreeBSD, and evaluated the performance in an ad-hoc network system built with PCs running Dynamic Source Routing (DSR) protocol.
