针对传统数据传输机制能耗较大,不利于无线传感器网络(WSNs)寿命延长的问题,提出一种基于mini-slot交叉MAC路由协议(CLRP-MS)位置叠取的节能WSNs数据传输机制。针对固定数据传输位置选取机制中,数据传输冲突几率较大,浪费网络吞吐量并增加能耗的问题,提出一种随机位置选取方式,并且给出基于mini-slot的改进版本和数据监听窗口选取方式,提高了数据传输的稳定性并降低能耗;利用数学分析给出定位函数的最佳选取方式,提高了定位准确度和合理性。通过在测试对象上的对比实验表明:所提CLRP-MS算法比对比算法PLOSA和ALOHA算法具有更好的数据传输性能和更低的能耗。
Aiming at problem of large energy consumption of traditional data transmission mechanism ,which is not conducive to wireless sensor networks (WSNs) for prolonging lifetime, a WSNs data transmission mechanism for energy saving based on CLRP-MS position stacking is proposed, Aiming at problem of large probability for data transmission conflict in fixed data transmission position selection mechanism, which wastes network throughput and increases energy consumption, a random position selection method is proposed, and its modified version based on mini-slot is also desiged,then selection method of data monitoring windows is presented,which improves stability of data transmission and reduces energy consumption; mathematical analysis is used for the best positioning function selection mode, which improves positioning accuracy and rationality; contrast experiment on test object show that,the proposed CLRP-MS algorithm has both better performance on data transmission and lower energy consumption than PLOSA algorithm and the ALOHA algorithm.
