摘要： A multi-path routing method is provided a multi-path routing method for selecting appropriate multiple paths when information sensed from a source node is transmitted to a sink node in wireless sensor networks. The source node for transmitting the sensed information first transmits a Hello message to the sink node to identify the existence and position of the sink node. The sink node receives the Hello message and then re-transmits the Hello message with respect to all the received Hello messages. Respective middle nodes accumulate distances between the middle nodes while the Hello message is transmitted to the source node through a reverse path of the Hello message, and all the middle nodes maintain a real distance from the sink node. The source node receiving all the Hello messages can rout a plurality of appropriate paths through Hop-by-hop to the sink node by providing respective weights to an energy remaining amount, an appropriate transmission radius and a real distance from the sink node. Accordingly, priorities can be provided to lifetime of the source node, average energy consumption and the shortest path by adjusting the respective weights when routing the plurality of paths. In addition, appropriate paths can be routed considering the transmission success rate of a path, and a load balancing effect can be obtained using path cost.

摘要翻译： 提供多路径路由方法，用于当从源节点感知的信息被发送到无线传感器网络中的汇聚节点时，选择适当的多个路径的多路径路由方法。 用于发送感测信息的源节点首先向宿节点发送一个Hello消息，以识别宿节点的存在和位置。 汇聚节点接收到Hello消息，然后针对所有收到的Hello消息重新发送Hello消息。 各个中间节点累积中间节点之间的距离，而Hello消息通过Hello消息的反向路径发送到源节点，并且所有中间节点与sink节点保持实际距离。 接收所有Hello消息的源节点可以通过向能量节点提供相应的权重，从能量剩余量，适当的传输半径以及从宿节点的实际距离，逐跳跳过多个适当的路径。 因此，当路由多个路径时，可以通过调整相应权重来提供源节点的寿命，平均能量消耗和最短路径的优先级。 此外，考虑到路径的传输成功率，可以路由适当的路径，并且可以使用路径开销获得负载平衡效果。
