摘要：User cooperation in wireless networks implemented on the Network Protocollayer level attains a higher stable throughput and improved transmission delay. Thecooperation is designed between a set of source user nodes transmitting to a common

destination, where users with channels providing a higher successful delivery probability,in addition to their own traffic, relay packets of other source users whose transmissionsto the destination fails. Each source user node is provided with an ample queue bufferhaving capacity to accumulate packets inadvertently received from other users in thesystem in addition to its own packets. Ranking mechanism facilitates in determining the“quality” of wireless channels, and the Acknowledgement mechanism facilitates incoordination of the transmissions in the system. The nodes exchange information on thequeues status, and decision is made by a scheduling controller on the priority oftransmission.
