摘要 无线传感器网络中的机会路由协议—MORE协议,即独立于MAC层的机会路由和编码协议,从对MORE协议的学习中,得知MORE协议在源节点准备发送数据包时,首先将K个数据包随机地分成批(batch)进行流内随机网络编码,再以广播的形式发送出去,这种提前设定好批的大小的方法不能满足实时的要求,对信道利用率和时延造成影响。针对MORE协议的这种弊端引入一种根据块时延的大小自主适应选择数据块大小的算法对MORE协议进行优化。 wireless sensor network opportunity routing MORE protocol is independent of the MAC layer routing and coding protocol. From the MORE protocol of the study, told the MORE protocol to send data packets in the source node, the K data packets are randomly divided into group （ batch ）to flow within a random network coding, and then in the form of broadcast is sent out, the predetermined number of size method cannot meet the real time requirements, on the the channel utilization rate and delay effects. Based on the MORE protocol is introduced according to this abuse of a block of time delay size self adapted to select the size of the data blOcks of the algorithm on the MORE protocol optimization.
