| 摘 要： | 针对特定的应用场合,考虑低速率无线个人局域网(LR-WPAN)网络节点的能耗问题,提出了一种基于CSMA/CA与TDMA相结合的传输方法。方法以网络同步为前提,通过增加网络休眠时间和划分数据传输时间槽等措施,降低网络的整体功耗。实验结果表明,所提方法在增加路由节点的休眠时间和减少终端节点载波侦听功耗方面都优于CSMA/CA算法,延长了网络生命周期。

| Abstract: | A transmission method based on the combination of CSMA/CA and TDMA was proposed considering the low rate wireless personal area network （LR-WPAN） problem of the energy consumption of network nodes for specific applications.The method starts from the premise of network synchronization reducing the overall power consumption by increasing network sleep time and partitioning the data transmission time slots.The experimental results show that,the method is better than the CSMA/CA algorithm in terms of increasing Router sleep time and reducing power consumption of End Device carrier sensing.And the method also prolongs the life span of network. |
