摘　　要：基于无线传感器网络的应用层多播特性,提出了一个灵活的多播生成树算法MSTA(Multicast Spanning Tree Algo-rithm)。MSTA以一种动态的,分散的,递增的方式构建一个覆盖多播树。它不仅可以满足性能目标和各种应用需要,而且MSTA具有高度自适应性,即MSTA可响应移动和拥塞而重新配置多播树。MSTA算法在应用层实现,并具有部署简单,与底层协议独立等应用层协议的优点。仿真结果表明MSTA比ODMRP有着显著的优良性能。A flexible multicast spanning tree algorithm based on wireless sensor network was proposed,which called MSTA（Multicasting Spanning Tree Algorithm）.MSTA constructs an overlay multicast tree in a dynamic,decentralized and incremental way.It not only can satisfy the performance goals and the needs of a wide range of applications.But also it is highly adaptive：it reconfigures the tree in response to mobility or congestion.In addition,MSTA has advantages of an application layer protocol of simplicity of deployment and independence from lower layer protocols.Compared with ODMRP,MSTA performs significantly.
