下面结合说明书附图， 对本发明实施例进行详细描述。
在本发明实施例中， 无线传感网包括： 网络侧设备和移动汇聚节点。 移 动汇聚节点可以为各种类型的移动终端，例如，个人数字助理（ Personal Digital Assistant, PDA ). 移动电话等， 并且在该无线传感网中包括至少一个移动汇 聚节点。 当网络侧设备确定发送待发送数据时， 与移动汇聚节点进行通信， 将待发送数据发送给移动汇聚节点， 移动汇聚节点再将接收到的数据上传至 上层网络。
图 1 为本发明实施例提供的无线传感网建立通信的过程， 具体包括以下 步骤：
SI 01 : 网络侧设备确定发送待发送数据时， 向移动汇聚节点广播唤醒信 号。
在本发明实施例中， 网络侧设备包括： 传感器节点和唤醒节点。 其中， 传感器节点用于对周围环境的探测和感知， 在确定发送待发送数据时， 指示 唤醒节点向移动汇聚节点广播唤醒信号； 唤醒节点用于向移动汇聚节点广播 该唤醒信号。
当网络侧设备确定发送待发送数据时， 即网络侧设备中的传感器节点确 定发送待发送数据时， 向唤醒节点发送指示信息， 指示该唤醒节点向移动汇 聚节点广播唤醒信号； 或传感器节点确定发送待发送数据时， 向唤醒节点发 送该待发送数据， 指示该唤醒节点向移动汇聚节点广播唤醒信号。
其中， 唤醒节点可以是无线传感网本身的节点， 如传感器节点， 也可以 是单独定义的节点。 为了减少无线传感网的复杂度及冗余度， 在本发明实施 例中， 该唤醒节点可以为增加了具有广播唤醒信号功能的传感器节点。
S 102： 该网络侧设备接收至少一个移动汇聚节点在接收到唤醒信号后广 播的接入信号。
在本发明实施例中， 移动汇聚节点在接收到唤醒节点广播的唤醒信号后， 开始广播接入信号。 每个移动汇聚节点广播的接入信号中包含该移动汇聚节 点的标识信息。
S103 : 该网络侧设备根据接收到的各接入信号， 确定发送各接入信号的 移动汇聚节点， 并在确定出的移动汇聚节点中， 选择用以接收数据的移动汇 聚节点， 将该待发送数据发送给该选择出的移动汇聚节点。
其中， 每个移动汇聚节点广播的接入信号中包含该移动汇聚节点的标识 信息， 网络侧设备可以根据各接入信号中包含的移动汇聚节点的标识信息， 确定发送各接入信号的移动汇聚节点， 并在各接入信号分别包含的移动汇聚 节点的标识信息中， 选择用以接收数据的移动汇聚节点的标识信息， 将该待 发送数据发送给选择出的该标识信息对应的移动汇聚节点。 由于该网络侧设备通过与移动汇聚节点进行通信， 将该待发送数据发送 给移动汇聚节点， 移动汇聚节点再将接收到的该数据上传至上层网络， 因此， 当该网络侧设备接收到两个或多个移动汇聚节点广播的接入信号时， 只需要 选择该两个或多个移动汇聚节点中的一个进行通信， 就可以将待发送数据通 过该移动汇聚节点上传至上层网络。
其中， 该网络侧设备通过一跳传送或多跳传送的方式， 将待发送数据发 送给移动汇聚节点。 该一跳传送的方式为， 当该网络侧设备与该移动汇聚节 点的距离比较近时， 该网络侧设备直接将该待发送数据发送给该移动汇聚节 点。 该多跳传送的方式为， 当该网络侧设备与该移动汇聚节点的距离比较远 时， 该网络侧设备将该待发送数据发送给其他距离该移动汇聚节点比较近的 网络侧设备， 通过距离该移动汇聚节点比较近的网络侧设备， 将待发送数据 发送给该移动汇聚节点。 例如， 网络侧设备中的传感器节点 a、 b和 c与移动 汇聚节点的距离 La、 Lb和 Lc的关系为 La〉Lb >Le, 当传感器节点 a将待发送 数据发送给该移动汇聚节点时， 采用该多跳传送的方式， 具体为， 传感器节 点 a先将该待发送数据发送给传感器节点 b，传感器节点 b再将该待发送数据 发送给传感器节点 c，最后传感器节点 c将该待发送数据发送给该进行数据发 送的移动汇聚节点。
在上述过程中， 网络侧设备确定发送待发送数据时， 向移动汇聚节点广 播唤醒信号， 移动汇聚节点只有在接收到该唤醒信号后， 才进行接入信号的 广播， 避免了作为该移动汇聚节点的移动终端大量的电量的消耗。
在本发明实施例中， 当网络侧设备中的唤醒节点为增加了具有广播唤醒 信号功能的传感器节点时， 在该无线传感网中选择可以作为该唤醒节点的传 感器节点的方法为， 预先设定一些传感器节点作为唤醒节点， 或者将电量较 强、 接收信号强度较好的传感器节点作为唤醒节点。 在本发明实施例中， 唤 醒节点与传感器节点的組网方式可以以簇为单位， 其中， 可以将每个簇的簇 头作为唤醒节点。
针对每个簇， 当该簇中的传感器节点确定发送待发送数据时， 指示作为 唤醒节点的该簇的簇头广播唤醒信号。 其中， 当该唤醒节点接收到该传感器 节点发送的指示信息时， 唤醒节点广播唤醒信号， 移动汇聚节点接收到该唤 醒信号后广播接入信号， 与该传感器节点进行通信。
图 2 为本发明实施例提供的以唤醒节点接收到传感器节点发送的指示信 息为例， 无线传感网建立通信的过程， 具体包括以下步骤：
S201 : 传感器节点确定发送待发送数据时， 向唤醒节点发送指示信息。 S202: 唤醒节点接收到该指示信息后， 开始广播唤醒信号。
其中， 该唤醒节点按照设定的时间间隔， 周期性的广播该唤醒信号。 S203 : 该传感器节点接收至少一个移动汇聚节点在接收到该唤醒信号后 广播的接入信号。
S204 : 该传感器节点根据接收到的各接入信号， 在发送各接入信号的移 动汇聚节点中， 选择进行数据发送的移动汇聚节点， 将待发送数据发送给选 择的该移动汇聚节点。
在本发明实施例中， 作为移动汇聚节点的移动终端并非一直开启传感网 通信功能， 而是按照设定的时间间隔， 周期性的开启该传感网通信功能， 即 根据设定的时间间隔将自身唤醒。 只有该移动终端在自身唤醒的时间长度内， 即开启该传感网通信功能时， 该移动终端才能对接收到的唤醒信号进行解析， 从而进行接入信号的广播。 当该移动终端不在自身唤醒的时间长度内， 即关 闭该传感网通信功能时， 即使唤醒节点进行唤醒信号的广播， 该移动汇聚节 点也不能对接收到的唤醒信号进行解析， 而只能丢弃该唤醒信号， 不能进行 接入信号的广播。
并且， 为了减少同一区域内同时广播接入信号的移动汇聚节点的数量， 以减小移动汇聚节点之间存在的严重的干扰， 本发明实施例中的移动汇聚节 点在自身唤醒的时间长度内， 即在开启传感网通信功能时接收到该唤醒信号， 还要根据自身当前的电量值、 自身当前的接收信号强度值和其他自身的状态 信息中的一种或几种， 判断自身是否进行接入信号的广播。
下面以该移动汇聚节点根据自身的剩余电量和自身的信号强度， 判断自 身是否进行接入信号的广播为例， 对该过程进行详细说明。
图 3 为本发明实施例提供的移动汇聚节点接收唤醒信号， 并判断自身是 否进行接入信号的广播的过程， 具体包括以下步骤：
S301 : 移动汇聚节点接收唤醒节点广播的唤醒信号， 判断是否对该唤醒 信号进行解析， 当确定对该唤醒信号进行解析时， 进行步骤 S302， 否则进行 步骤 S305。
在本发明实施例中， 移动汇聚节点根据设定的时间间隔将自身唤醒， 当 该移动汇聚节点在自身唤醒的时间长度内， 即开启传感网通信功能时接收到 唤醒信号， 则对接收到的唤醒信号进行解析， 当该移动汇聚节点不在自身唤 醒的时间长度内， 即关闭传感网通信功能时接收到唤醒信号， 则不能对接收 到的唤醒信号进行解析， 丢弃该唤醒信号。
在本发明实施例中， 当作为该移动汇聚节点的移动终端的移动速度很快 时， 若接收到了该移动终端目前所在区域内唤醒节点广播的唤醒信号， 但不 在自身唤醒的时间长度内， 即关闭传感网通信功能时， 则会丟弃该唤醒信号， 等到了设定的时间间隔， 开启传感网通信功能时， 该移动终端已经不在该区 域内， 这样就会错过与该区域内的传感器节点进行通信的机会。 因此， 在本 发明实施例中， 该作为移动汇聚节点的移动终端将自身唤醒的时间间隔， 即 开启该传感网通信功能的时间间隔， 可以根据自身的移动速度来调节， 自身 的移动速度越快， 则该时间间隔越短。
S302 : 该移动汇聚节点确定自身当前的电量值， 将确定的电量值与保存 的电量阈值进行比较， 当该电量值大于保存的该电量阈值时，进行步骤 S303 , 否则进行步骤 S306。
其中， 该移动汇聚节点自身保存电量阈值， 当该移动汇聚节点当前的电 量值大于该电量阈值时， 则继续进行该移动汇聚节点的接收信号强度的判断， 否则确定自身当前的电量值不足， 不广播接入信号。
S303 : 该移动汇聚节点确定自身当前的接收信号强度值， 将确定的接收 信号强度值与保存的信号强度阈值进行比较， 当该接收信号强度值大于保存 的该信号强度阈值时， 进行步骤 S304， 否则进行步骤 S306。
其中， 该移动汇聚节点自身保存信号强度阈值， 当该移动汇聚节点当前 的接收信号强度值大于该信号强度阈值时， 广播接入信号， 否则确定自身当 前的接收信号强度值不够强， 不广播接入信号。
并且， 该移动汇聚节点判断自身当前的电量值是否大于保存的电量阈值 的过程， 与判断自身当前的接收信号强度值是否大于保存的信号强度阈值的 过程的顺序可以为任意。
S304: 该移动汇聚节点向网络侧设备广播接入信号。
该移动汇聚节点确认自身当前有足够的电量值， 且自身的接收信号强度 值较强， 开始广播接入信号。
S305 : 该移动汇聚节点丢弃该唤醒信号。
该移动汇聚节点不在自身唤醒的时间长度内， 即处于关闭传感网通信功 能的状态时， 不能对该唤醒信号进行解析， 因此丢弃该唤醒信号。
S306: 该移动汇聚节点不广播接入信号。
当移动汇聚节点在自身唤醒的时间长度内接收到唤醒信号时， 若直接进 行接入信号的广播， 那么一些当前电量值不足， 或接收信号强度值不强的移 动汇聚节点即使与该传感器节点进行通信， 则该通信的质量也会很低， 甚至 不能接收到该传感器节点发送的待发送数据， 并且该移动汇聚节点广播的接 入信号也会干扰到其他移动汇聚节点进行接入信号的广播。 因此， 为了提高 移动汇聚节点与网络侧设备的通信质量， 移动汇聚节点在确定自身当前有足 够的电量值， 且信号强度值也较强时， 才开始进行接入信号的广播。
在上述过程中， 该移动汇聚节点只有在确认自身当前的电量值大于自身 保存的电量阈值， 且自身的接收信号强度值大于自身保存的信号强度阁值， 才进行接入信号的广播， 也进一步避免了作为该移动汇聚节点的移动终端大 量的电量的消耗。 同时， 由于作为该移动汇聚节点的移动终端只有在确认当 前自身有足够的电量值， 且自身的接收信号强度值较强时才广播接入信号， 降低了同一区域内同时广播接入信号的移动汇聚节点的数量， 从而有效的降 低了移动终端之间的严重干扰。
例如， 在同一区域内有 10个移动终端在自身唤醒的时间长度内接收到唤 醒信号， 但其中只有 5个移动终端有足够的电量值， 且接收信号强度值较强， 则只有该 5个移动终端进行接入信号的广播， 相比于现有技术中 10个移动终 端同时进行接入信号的广播， 有效的降低了移动终端之间的严重干扰。
在本发明实施例提供的当唤醒节点接收到传感器节点发送的指示信息 时， 传感器节点与移动汇聚节点建立通信的过程中， 若该传感器节点只接收 到一个移动汇聚节点广播的接入信号， 则直接选择广播该接入信号的移动汇 聚节点作为进行数据发送的移动汇聚节点， 并将待发送数据发送给该移动汇 聚节点。 若接收到两个或多个移动汇聚节点广播的接入信号， 由于只需要选 择一个移动汇聚节点进行通信， 就可以将待发送数据通过该移动汇聚节点上 传至上层网络， 因此该传感器节点 4艮据接收到的各接入信号， 确定发送各接 入信号的移动汇聚节点中， 可以根据在确定出的移动汇聚节点中， 任意选择 一个移动汇聚节点作为用以接收数据的移动汇聚节点， 并将待发送数据发送 给该移动汇聚节点。
为了提高该传感器节点与移动汇聚节点的通信质量， 提高该待发送数据 的发送效率， 在本发明实施例中， 当该传感器节点接收到两个或多个移动汇 聚节点广播的接入信号时， 确定接收到的各接入信号的强度， 选择发送接入 信号的强度最强的移动汇聚节点作为用以接收数据的移动汇聚节点， 即选择 该两个或多个移动汇聚节点中信号强度最强的一个进行通信， 将该待发送数 据发送给该移动汇聚节点。
图 4 为本发明实施例提供的该传感器节点选择用以接收数据的移动汇聚 节点对应的标识信息的过程， 具体包括以下步骤：
S401： 该传感器节点确定接收到各接入信号的强度。
S402 : 该传感器节点选择发送接入信号的强度最强的移动汇聚节点作为 用以接收数据的移动汇聚节点。
在上述过程中， 传感器节点将接收到的每个接入信号的强度进行比较， 确定强度最强的一个接入信号， 并选择发送该接入信号的移动汇聚节点作为 用以接收数据的移动汇聚节点， 提高了传感器节点与移动汇聚节点的通信质 量。
在本发明实施例中， 由于当网络侧设备确定发送待发送数据时， 向移动 汇聚节点广播唤醒信号的方式还可以为， 该网络侧设备中的传感器节点确定 发送待发送数据时， 将待发送数据发送给该唤醒节点， 指示该唤醒节点广播 唤醒信号。 采用该方式指示唤醒节点广播唤醒信号时， 由于该传感器节点已 经将该待发送数据发送给了唤醒节点， 则将该待发送数据通过移动汇聚节点 上传至上层网络的方式为， 该唤醒节点与移动汇聚节点进行通信， 将该待发 送数据发送给移动汇聚节点， 移动汇聚节点再将该待发送数据上传至上层网 络。
图 5 为本发明实施例提供的以唤醒节点接收到传感器节点发送的待发送 数据为例， 无线传感网建立通信的过程， 具体包括以下步骤：
S501 : 传感器节点确定发送待发送数据时， 向唤醒节点发送该待发送数 据。
S502: 唤醒节点接收到该待发送数据后， 开始广播唤醒信号。
其中， 该唤醒节点节按照设定的时间间隔， 周期性的广播该唤醒信号。 S503 : 该唤醒节点接收至少一个移动汇聚节点在接收到该唤醒信号后广 播的接入信号。
S504 : 该唤醒节点根据接收到的各接入信号， 在发送各接入信号的移动 汇聚节点中， 选择进行数据发送的移动汇聚节点， 将该待发送数据发送给选 择的该移动汇聚节点。
在本发明实施例中， 由于该唤醒节点为增加了具有广播唤醒信号功能的 传感器节点， 并具体为一簇传感器节点中的簇头， 因此该唤醒节点也可以使 用传感器节点的功能， 与该移动汇聚节点进行通信， 即将待发送数据发送给 移动汇聚节点。
在上述过程中， 作为移动汇聚节点的移动终端也根据设定的时间间隔将 自身唤醒。 并且为了减少同一区域内同时广播接入信号的移动汇聚节点的数 量， 以减小移动汇聚节点之间存在的严重干扰， 本发明实施例中的移动汇聚 节点在自身唤醒的时间长度内接收到唤醒信号时， 根据自身当前的电量值、 自身当前的接收信号强度值和其他自身的状态信息中的一种或几种， 判断自 身是否进行接入信号的广播的过程， 与本发明实施例提供的移动汇聚节点接 收唤醒信号， 并判断自身是否进行接入信号的广播的过程基本相同， 这里就 不——赘述。
并且， 在上述过程中， 为了提高该唤醒节点与移动汇聚节点的通信质量， 提高该待发送数据的发送效率， 在本发明实施例中， 该唤醒节点选择用以接 收数据的移动汇聚节点的过程， 与本发明实施例提供的该传感器节点选择用 以接收数据的移动汇聚节点的过程基本相同， 这里就不一一赘述。
下面以一个具体的实施方式， 对上述实现方式进行详细说明。
图 6 为本发明实施例提供的网络侧设备中的传感器节点确定发送待发送 数据时， 与作为移动汇聚节点的移动终端建立通信的过程， 具体包括以下步 骤：
S601 : 传感器节点确定发送待发送数据时， 向唤醒节点发送指示信息。 S602: 该唤醒节点接收到该指示信息后， 开始广播唤醒信号。
其中， 该唤醒节点按照设定的时间间隔， 周期性的广播该唤醒信号。 S603 : 移动汇聚节点接收唤醒节点广播的唤醒信号， 判断是否对该唤醒 信号进行解析， 当确定对该唤醒信号进行解析时， 进行步骤 S604 , 否则进行 步骤 S609。
也即， 移动汇聚节点判断是否在自身唤醒的时间长度内接收到唤醒信号， 若是， 则广播接入信号， 否则丢弃唤醒信号， 不广播接入信号。
S604 : 该移动汇聚节点确定自身当前的电量值及自身当前的接收信号强 度值， 将确定的电量值与保存的电量阈值进行比较， 并将确定的接收信号强 度值与保存的信号强度阈值进行比较， 当该电量值大于保存的该电量阁值， 且该接收信号强度值大于保存的信号强度阂值时， 进行步骤 S605 , 否则进行 步骤 S610。
S605 : 该移动汇聚节点广播接入信号。
S606: 该传感器节点接收至少一个移动汇聚节点广播的接入信号。
S607 : 该传感器节点确定接收到的各接入信号的强度。
S608 : 该传感器节点选择发送接入信号的强度最强的移动汇聚节点， 将 该待发送数据发送给选择的该移动汇聚节点。
其中， 该传感器节点通过一跳传送或多跳传送的方式， 将该待发送数据 发送给移动汇聚节点。
S609: 该移动汇聚节点丟弃该唤醒信号。
S610: 该移动汇聚节点不广播接入信号。
在上述过程中， 传感器节点确定发送待发送数据时， 指示唤醒节点广播 唤醒信号， 移动汇聚节点只有在自身唤醒的时间长度内接收到该唤醒信号时， 才能对该唤醒信号进行解析， 从而判断自身是否进行接入信号的广播， 并在 确认自身可以进行接入信号的广播时广播接入信号， 避免了作为该移动汇聚 节点的移动终端大量的电量的消耗。 同时， 由于移动汇聚节点只有在确定自 身可以进行接入信号的广播时， 才广播接入信号， 从而减少了同一区域内同 时广播接入信号的移动汇聚节点的数量， 因此有效的降低了移动汇聚节点之 间存在的严重的干扰。
并且， 在上述过程中， 传感器节点确定发送待发送数据时， 也可以将该 待发送数据发送给唤醒节点， 以指示该唤醒节点广播唤醒信号。 采用该方法 时， 唤醒节点与作为移动汇聚节点的移动终端建立通信的过程， 与本发明实 施例提供的当传感器节点确定发送待发送数据时， 与作为移动汇聚节点的移 动终端建立通信的过程基本相同， 这里就不——赘述。
