A packed transmission scheme for improved throughput over multi-hop routes of a wireless multihop network

摘要

The invention is directed in general to packet transmission mechanisms for multi-hop wireless networks that optimize throughput over multi-hop routes, mostly by mitigating self-interference and congestion.;A method for transmitting packets through a wireless multi-hop network is prposed wherein data packets may gravel along a multi-hop route (10) in a bi-directional way, which comprises a source node (20), a plurality of relay nodes (301 to 30n) and a destination node (40), where nodes can only hear each other if they are a couple of hops away from each other. In particular, each node comprises a single wireless interface (33) which is adapted to receive data packets from on of its adjacent nodes and to transmit packets in both directions along the route (10). Furthermore, each relay node (301 to 30n) comprises a buffer (32) having a size for storing only one packet so that a relay node can only send a packet to its respective preceding or succeeding relay node, if there is no packet stored.
