摘　　要：综合了基于距离和基于角度的两种路由方案的优势,提出一种新的基于距离和角度的路由方案DDR(Distance and Di-rection based Routing),将它作为选取下一跳的评判标准。仿真结果表明,DDR能够在能耗和延时之间达到有效的折中,其综合能耗和延时性能要优于单一的基于距离和基于角度的路由方案。A new distance and direction based routing（DDR） scheme,which combines distance based and direction based geographical strategy as the standard for selecting the next hop, is proposed.The results of simulation experiments show that DDR achieves an efficient trade-off between energy consumption and delivery latency.The overall performance of DDR in terms of energy consumption and delivery latency is better than those of both only distance based and direction based scheme.
