摘　　要：针对无线传感器网络中不同业务对QoS的不同要求,提出了一种新的QoS路由算法—EBQoS算法。算法通过记录邻居节点到Sink节点的最小跳数信息建立到Sink节点的多条路径,并根据信息包的QoS要求和节点剩余能量选择合适的路径进行路由。通过仿真实验与顺序分配路由(SAR)算法的比较,结果表明该路由算法在提供差别服务和提高网络生存期方面具有明显的优势。Considering the different QoS requirements in different services, a new QoS Routing algorithm-EBQoS algorithm was proposed. The algorithm built multiple paths by memorizing the minimum hops to sink node of the neighbors. Then data was sent by the path that satisfied its QoS requirements and had enough residual energy. According to the comparisons with the SAR routing algorithm, this algorithm has obvious advantages in providing different services and prolonging the network lifetime.
