Wireless sensors have been described in detail in the previous article. As the focus of future technological development, wireless sensors are one of the two major technologies-Wireless Technology + micro-sensing technology. This article focuses on the MAC protocol classification of wireless sensor networks. Classification Based on MAC protocol of wireless sensor networks using node Access Channels Currentl

A wireless sensor network consists of a large number of low-cost micro-sensor nodes deployed in the monitoring area. A multi-hop self-organizing network system is formed through wireless communication, it is mainly used to collect, disseminate, and process sensing information. Unlike traditional wireless self-organizing networks, wireless sensor networks have a large number of nodes and are densely distributed. Due to environmental impact and energy depletion, nodes are prone to faults; environm
