Embodiment Construction
[0014] Such as figure 1 Shown is a network topology diagram of a wireless sensor network protocol based on IEEE 802.15.4. A PAN wireless short-range local area network 10 involved in the present invention includes two types of equipment, a central coordinator 100 and terminal nodes 101-10n, wherein the central coordinator 100 is responsible for the establishment of the network, and sends Beacon beacon frames as a clock source. The terminal nodes 101-10n form a star network with the central coordinator 100, establish a connection with the central coordinator 100 through a single hop, and realize two-way transmission of wireless data. No direct connection can be established between the terminal nodes 101-10n. The central coordinator 100 also acts as an external gateway of the wireless local area network 10 , and realizes data interaction with an upper layer network or system 111 through a wired or wireless interface 110 . In this way, the wireless data from the terminals 101~...
