摘要： 在无线传感器网络中，普遍采用周期性广播元数据的数据包来判断代码分发，存在能耗过大的问题。为此，提出一种低能耗的代码分发协议。该协议在节点正常通信时便可判断是否需要代码分发。仿真结果表明，与现有的分发协议相比，该协议可降低代码分发的能量消耗。

Abstract: For the too much energy consumption issue in the commonly used periodical broadcasting metadata packages to determine whether code dissemination is needed in Wireless Sensor Networks(WSN), a low energy consumption code dissemination protocol is proposed. That is whether code dissemination is necessary can be determined when the sensor node is under normal communication. Simulation result shows that the protocol can reduce the energy consumption, compared with now code dissemination protocols.
