Description

Mesh网络处理方法、装置、设备和存储介质 技术领域
本发明实施例涉及终端设备技术领域，尤其涉及一种Mesh网络处理方法、装置、设备和存储介质。
背景技术
无线网状网络简称无线Mesh网络，也称为“多跳(multi-hop)”网络，它是一种与传统无线网络完全不同的新型无线网络技术。
无线Mesh网络，由根节点、中间节点和叶子节点组成。根节点是一个无线Mesh网络与外部通信的唯一出口，根节点支撑起整个无线Mesh网络，将无线Mesh网络内部的数据转发到外部。中间节点是整个无线Mesh网络内部具有转发功能的节点，接收根节点发送的数据并转发至叶子节点，同时也接收叶子节点的数据并转发至根节点。叶子节点没有转发功能，只能接收由中间节点发送的数据，或者将自身产生的数据发送至中间节点。
无线Mesh网络在组网的过程中，只要打开设备，连接电源，设备自动进行自我配置，确定最佳的传输路径。这样，无线Mesh网络在组网过程中可能会出现多个根节点。图1是现有技术中存在多个根节点的无线Mesh网络的结构示意图，如图1所示，无线Mesh网络有3个根节点110，多个中间节点120和多个叶子节点130，组成了3个无线Mesh子网络，无线Mesh子网络10、无线Mesh子网络20、无线mesh子网络30。这种组网方式会导致处于不同无线mesh子网络内的中间节点120和叶子节点130间无法直接通信，需要通过所在无线 mesh子网络的根节点转发才能进行通信，这种数据传输方式会增加根节点的业务处理量。

具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
实施例一
图2是本发明实施例一中的Mesh网络处理方法的流程图，本实施例可适用于选择Mesh网路中根节点的情况，该方法可以由Mesh网络中的节点来执行，进一步的，该方法可以由Mesh网络中的根节点来执行，该方法主要包括如下步骤：
步骤110、若检测到Mesh网络中存在根节点冲突，则获取冲突的至少两个根节点的根节点信息。
在本实施例中，检测到Mesh网络中存在根节点冲突，包括：若接收中间节点广播的根节点冲突，则检测到Mesh网络中存在根节点冲突；或者，若从中间节点和/或其他根节点接收的根节点信息，与本机根节点信息不同，则检测到Mesh网络中存在根节点冲突。
Mesh网络中的各个节点在组成网络之后，将自己所属网络内的根节点信息放在自定义的信息元素，也称为网络IE中，并通过WIFI信标进行广播。进一步的，中间节点在检测到存在根节点冲突之后，将根节点冲突信息放在一个自定义的信息元素中，也称为根节点冲突IE并通过WIFI信标进行广播。
在本实施例中，Mesh网络中的各个根节点在接收到中间节点广播的WIFI信标之后，检测WIFI信标中是否携带有根节点冲突IE，其中根节点冲突IE由中间节点定义并通过WIFI信标进行广播，若信标中携带有根节点冲突IE，则检测到Mesh网络中存在根节点冲突。
在本实施例中，还提供另外一种检测Mesh网络中存在根节点冲突的方法。接收中间节点或者其他根节点广播的网络IE，检测网络IE中是否存储有根节点信息，若是存储有根节点信息，则判断网络IE中携带的根节点信息与本机的根节点信息是否相同。若网络IE中携带的根节点信息与本机的根节点信息不相同， 则将测到Mesh网络中存在根节点冲突。
步骤120、依据冲突的至少两个根节点的根节点信息，从冲突的至少两个根节点中选择新的根节点作为Mesh网络中使用的根节点。
在本实施例中，根据冲突的至少两个根节点的根节点信息，从冲突的两个根节点中选择新的根节点作为Mesh网络中使用的根节点。当检测到存在根节点冲突时，说明Mesh网络中存在多个根节点，根据根节点信息从多个根节点中选择一个根节点作为Mesh网络中使用的根节点，其他的根节点则断开与Mesh网路中外部IP网络的连接，建立与新的根节点的连接。通过这种选择新的根节点方法，可以删除Mesh网络中其他的根节点，只留一个根节点，消除多个网络的存在，让所有设备处在同一个网络里。
