摘要: Multi-hop wireless networks are vulnerable to free-riders because they require nodes forward packets for each other. Deployed routing protocols ignore this issue while proposed solutions incorporate complicated mechanisms with the intent of making free-riding impossible. We present Catch, a protocol that falls between these extremes. It achieves nearly low mechanism requirements former imposing as effective barriers latter. Catch is made possible by novel techniques based on anonymous messages. These enable cooperative detect nearby and disconnect them from rest network. has overhead broadly applicable across traffic workloads. evaluate it an 802.11 testbed well through simulation.
