In Ad-Hoc networks, user nodes, in addition to handling their own traffic, also act as routers and contribute to network connectivity for the benefit of other nodes. With such a collaborative routing technique, hybrid Ad-Hoc networks i.e. Ad-Hoc networks interconnected to an infrastructure-based network via an Access Point (AP) - become a means to extend the network coverage of APs. However, nodes may not be continuously available to route the traffic of other nodes. This can result in severe bandwidth degradation if nodes (partially) drop data packets. In this paper, we propose a new routing protocol suite called MOOR which enables Ad-Hoc nodes to discover dynamically the most reliable routes toward the AP. It is based on a reputation cross-layer system which runs on the AP side and makes use of the TCP control mechanisms to evaluate node cooperation.
