1. 无线自组网:
无线自组织网络是在没有任何框架或基础设施的情况下部署的无线网络。这包括无线网状网络、移动自组织网络和车载自组织网络。它的历史可以追溯到国防高级研究计划局 (DARPA) 和分组无线电网络 (PRNET),它们演变成生存自适应无线电网络 (SARNET) 计划。无线自组织网络,尤其是移动自组织网络 (MANET),正在快速增长,因为它们使通信变得更简单和可访问性越来越高。在任何情况下,由于无线通信的拓扑相关行为以及它们对拓扑动态的分布式和自适应操作,它们的约定或协议通常将难以构建。他们可以在任何时候自信地行动。因此,MANET 的网络拓扑可能会在不可预测的时间随机且快速地变化。这使得路由变得困难,因为拓扑不断变化,并且不能期望节点具有稳定的数据存储。
应用:
- 数据挖掘
- 军事战场
- 商业部门
- 个人局域网或蓝牙
2. 无线传感器网络:
无线传感器网络可以表征为一个设备系统,表示为节点,这些节点可以检测环境并通过远程或无线连接传递从被监控的领域(例如,区域或体积)积累的数据。它可以被描述为一个节点系统,可以很好地感知并控制环境,从而实现人或计算机与周围环境之间的关联。信息可能通过不同的跳转被发送到一个接收器(表示为控制器或监视器),该接收器可以在本地使用它或通过门户与不同的系统(例如,互联网)相关联。节点可以是固定的或移动的。
应用:
- 环境监测
- 卫生保健
- 定位和监控
