Routing in these networks is affected by some metrics, but the number of new connections especially is the crucial factor in delivering messages. Under this detection, we proposed every connection routing, which pay more attention to new connections between nodes but not the older ones. Further together with countdown timer and a fast buffer-released mechanism, every connection routing, are influenced by nodes speed, communication range and number, expiration time and simulation area. Buffer-release-enhanced weighted every connection routing may only increase processing time by the introducing of messages releasing time, but the benefit is lighter loaded buffers and higher efficiency of networks. The performance of buffer-release-enhanced weighted every connection routing is able to guarantees the validity of message delivery and improve the efficiency of the networks.]]>Jones, E.P.C., L.
