Channel and time slot scheduling method suitable for WIA-PA network

Abstract

The invention requests for protection of a channel and time slot scheduling method suitable for a WIA-PA network. The channel and time slot scheduling method includes that scheduling rules according to which channel and time slot scheduling is executed and a scheduling method meeting the scheduling rules are provided by combining actual WIA-PA network environment according to superframe structure of WIA-PA and characteristics of communication resource distribution; the scheduling rules include known conditions, hard conditions and scheduling priority which illustrate indicators in the scheduling method respectively; the scheduling method includes specifying scheduling of channels and time slot in a beacon state, a CAP state, an in-cluster communication stage and an inter-cluster communication stage in the WIA-PA superframe structure, and the method is used for scheduling the channels and the time slot of each equipment in the WIA-PA network; transmission of corresponding frames is arranged at corresponding stages according to the superframe structure of the WIA-PA, and all frames in the WIA-PA are ensured to be sent to a target node within a superframe period. By the channel and time slot scheduling method, scheduling of the channels and the time slot of the WIA-PA network is realized, the channels and the time slot are distributed for each equipment in the WIA-PA network, and requirements on time slot communication of the WIA-PA network are met.
