中文摘要：
传感器网络中，多径传输既要考虑负载均衡，又要考虑能量节约．本文提出一种能量敏感负载均衡的多径传输策略，数据基于决定性能量比例（DER）沿着多径传输，容易实现而且开销较小．同时，提出DEROA策略避免关键节点的过量负载．仿真结果表明DER可以进行有效的传输．
英文摘要：
Multipath must provide load balancing along with the energy-awareness in sensor networks. This paper proposes an energy-aware load-balancing delivery scheme. The packets can be transmitted along the multiple paths according to their Decisive Energy Ratio （DER）, which is the proportion of the minimum equivalent residual energy of each path to the sum of the minimum equivalent residual energy on all the paths. It is easy to be implemented and brings only a few overheads. Also, DER with Overload Avoidance （DEROA） is proposed to avoid heavy traffic on some critical nodes. The simulations show that DER can efficiently deliver packets.
