基于TCP的HTTP协议或者是依赖第三方框架传输的物联网通信设备，数据包比较大，应用在互联网中就显得庞大耗费资源，因此也提高了相应的设备成本，有的设备资源所限，则不能支持，造成设备使用的局限性。

图2示意性示出了根据本公开实施例的用于物联网设备间的数据传输方法的流程图。
如图2所示，该方法包括操作S210～S230。
在操作S210，处理待传输数据，生成验证标识。
在操作S220，采用不可靠传输协议发送所述待传输数据以及所述验证标识，使接收端能够基于所述验证标识验证所述待传输数据是否传输成功。根据本公开实施例，所述不可靠传输协议例如可以包括用户数据报协议(UDP)。

根据本公开实施例，所述接收端基于所述验证标识验证所述待传输数据是否传输成功，例如可以是通过循环冗余校验的方式进行验证。

根据本公开实施例，该预定运算例如可以在诸如异或运算等简单运算的基础上，增加另外的运算。例如，可以引入一个校验表，在每次异或运算结束时，将运算结果作为索引值，查找校验表中相应的值作为本次运算的运算结果。
在操作S321，判断是否存在下一字节，若存在，则继续执行操作S322，否则跳转到操作S323。
在操作S322，读取下一字节并与前次运算结果进行预定预算，获得当前运算结果，之后转入操作S321。
在操作S323，将当前运算结果作为验证字节。当最后一个字节即第N个字节运算完毕时，得到一个运算结果作为校验字节。根据本公开实施例，将种子字节以及校验字节连同待传输数据一起发送的接收端，使接收端能够基于同样的算法验证数据的完整性。

在操作S531，将当前运算结果与验证字节比较。
在操作S532，若最终的运算结果与验证字节一致，则表明数据传输成功，否则表示其中存在数据丢失，需要重发。
根据本公开实施例，所述方法还包括识别所述数据中不能传输的部分，以及基于预定规则，使用特定数据替代所述数据中不能传输的部分。例如，该不可靠传输协议不支持某些字符的传输，本公开实施例的方法可以将该些不支持的字符根据预定规则转换为可以传输的字符，在传输后，通过同样的规则将其还原。

本领域技术人员可以理解，本公开的各个实施例和/或权利要求中记载的特征可以进行多种组合或/或结合，即使这样的组合或结合没有明确记载于本公开中。特别地，在不脱离本公开精神和教导的情况下，本公开的各个实施例和/或权利要求中记载的特征可以进行多种组合和/或结合。所有这些组合和/或结合均落入本公开的范围。
以上对本公开的实施例进行了描述。但是，这些实施例仅仅是为了说明的目的，而并非为了限制本公开的范围。尽管在以上分别描述了各实施例，但是这并不意味着各个实施例中的措施不能有利地结合使用。本公开的范围由所附权利要求及其等同物限定。不脱离本公开的范围，本领域技术人员可以做出多种替代和修改，这些替代和修改都应落在本公开的范围之内。
