A Scheme Encouraging Mobile Nodes to Forward Packets via Multiple Wireless Links Aggregating System Between the Internet and Mobile Ad Hoc Networks

We have proposed a system that achieves high-speed and high-quality communication between mobile nodes and the Internet by using multiple network interfaces of multiple mobile nodes. In this system, adjacent mobile nodes connect to each other with short-range high-speed links and establish temporary networks. A mobile node in a temporary network simultaneously uses multiple links owned by the nodes in the network when it communicates with nodes outside the network. In this system, a part of data packets for one node have to be relayed by the other nodes in the temporary network. However, other nodes might not relay data packets unless they receive some profit from their contribution. In this report, we introduce credits as an incentive to network nodes to relay packets. We propose a method that provides secure credit exchanges between nodes relaying packets and a node requesting the relays, and the method provides a trusted third party that assists those nodes exchanging credits.
