| 摘 要： | 针对农田环境信息量丰富的特点,提出一种基于LEACH算法的改进型无线传感器网络路由算法--LEACH-SMC.在LEACH-SMC算法的稳态阶段,簇头节点到基站间通信采用临界距离来判断和选择多跳或单跳方式,在多跳方式中采用基于最小能量消耗的路由方式.应用Matlab对LEACH-SMC算法和LEACH算法进行仿真对比分析,结果表明, LEACH-SMC算法能提高网络有效覆盖面积并延长整个网络的寿命.

| Abstract: | An improvement of LEACH algorithm was proposed,named LEACH-SMC.The LEACH-SMC protocol algorithm was carried out round by round,and every round was divided into two sections of setup phase and steady station.A critical distance was specified for every cluster head to judge when to use the single-hop or the multi-hop mode between the cluster heads and the base station.The coverage area was greatly improved by the multi-hop manner,and this manner also provided practical value in the nodes distribution in the f... |
