【摘要】 为减少无线传感器网络(WSNs)大规模应用中出现的节点同步失效、数据丢失的问题,通过对现有WSNs应用系统的研究,提出了一种全网节点同步休眠机制下WSNs的自治愈方法。详细介绍了该方法的设计思路、实现方法及测试过程。测试结果表明:此方法可针对数据丢失和时间同步失效的节点进行节点自救,实现丢失节点的再入网、再同步,提高WSNs系统的稳定性,为WSNs的应用提供更好的条件。更多还原

【Abstract】 To reduce data loss and synchronization failure of node in large-scale applications of wireless sensor networks( WSNs),a kind of self-healing method of WSNs under sleeping mechanism is introduced by research of existing WSNs application system. Design ideas,implementation method of self-healing method and experimental process are discussed in detail. The experimental results show that this method can carry out node self-rescue aiming at data loss,and node of time synchronization failure,realize reaccess the Internet of lost node and resynchronization,improve system stability of WSNs and lay a foundation for further application of WSNs.更多还原
