  abstract	= {In this paper we present an new ad hoc routing system
		  based upon simple principles regarding the routing strategy
		  and the implementation approach. In the routing area we
		  (re-)introduce the end-to-end principle, letting the
		  communicating end nodes make the decisions concerning the
		  behaviour of intermediate nodes. We adopt a routing
		  strategy that is a mixture of on-demand and pro-active
		  routing in order to minimize the possible down-times of
		  communication paths. Implementation-wise we use explicit
		  ``resolution commands'' sent to neighbour nodes to provide
		  LUNAR functionality. A freely available implementation has
		  been produced that includes auto-configuration of IP
		  network addresses and default gateway routing, making LUNAR
		  a fully self-configuring ad-hoc routing solution which
		  supports both unicast and broadcast styles of
		  communication.}
