Based on the current situation of the network and the degree of the nodes , rdab calculates the relative degree of the nodes , decides which nodes need to relay and which nodes only need to receive . the higher the neighbor node ' s relative degree , the more uncovered nodes it can cover , so this kind of nodes can be selected to relay the broadcasting messages in the networks 该算法以密集节点的一次转发可覆盖更多节点为原则，动态的选择转发节点，即根据网络中节点的实时相对密度，每个需要发送数据分组的节点独立执行rdab算法，通过尽可能少的转发节点，到达覆盖全网的目的。
