Abstract [en]

NOVELTY - Several data packets are received in a receiving node from multi-transmitting nodes, and are decoded in a multi-user detection (MUD) mode. The decoded packets are then arranged sequentially and a correctly decoded packet is selected for forwarding. A packet acknowledge for each selected packet is transmitted to the multi-transmitting nodes. USE - For forwarding data packets in multi-hop network. ADVANTAGE - The performance of the multi-hop network is improved with respect to high throughput and less power consumption. The quality of service (QoS) support in the network is improved. The risk of congestion and buffer overflow in the network are reduced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) data packet forwarding system; and (2) communication node. DESCRIPTION OF DRAWING(S) - The figure shows a schematic process flow diagram of forwarding data packets.
