基于选择解码转发协作协议，从跨层设计的角度提出了一种新的分布式服务质量（QoS）路由算法，以最小化无线链路的总能耗.对于非协作和协作截断自动重传请求方案，首先分析了在Nakagami-m衰落信道下采用M-PSK和M-QAM符号时的误包率性能，然后推导了系统吞吐量。随后，在满足端到端吞吐量要求的同时最优地分配传输功率。在多项式复杂度下，利用传统的分布式最短路径算法，构造出包含非协作和协作积木级联的、总链路代价（定义为平均总消耗功率）最小的路由来承载信息流。与以往的非合作路由方案相比，该合作路由算法可以显著降低总能耗。
Based on the selection decode-and-forward cooperative protocol, a novel distributed quality of service (QoS) aware routing algorithm is proposed to minimise the total energy consumption of the wireless links from the cross-layer design perspective. For the non-cooperative and cooperative truncated automatic repeat request schemes, performance of packet error rate with M-PSK and M-QAM symbols over Nakagami-m fading channels is first analysed, and then system throughput is derived. Subsequently, transmission power is optimally allocated while satisfying the end-to-end throughput requirement. With polynomial complexity, using the traditional distributed shortest path algorithm, the route that includes a cascade of non-cooperative and cooperative building blocks and has the minimal total link cost (defined as the average total consumed power) is constructed to bear the information flow. In contrast to the previous non-cooperative routing schemes, this cooperative routing algorithm can significantly reduce the total energy consumption.
