First Claim
Patent Images
1. A method of two-stage adaptive frequency hopping for a clustered wireless sensor network (WSN), comprising the steps of:
- a) building a clustered wireless sensor network;
b) defining a superframe structure based on IEEE 802.15.4 according to a topology of the clustered wireless sensor network;
c) extending a beacon frame payload based on a beacon frame format of an IEEE 802.15.4 Media Access Control (MAC) layer; and
d) performing a two-stage adaptive frequency hopping mechanism on nodes based on the above superframe structure and the extended beacon frame of the IEEE 802.15.4 MAC layer.
