System and method to achieve differentiation fairness and services in an ad hoc network

摘要

By a method and a system for the (MAC) scheduling algorithm medium access control, using the control RTS / CTS message indicating the node status information, in order to achieve differentiated services and fairness use in the ad hoc network system and method of having, a distributed self-regulation approach. Local scheduling algorithm, near status for multi-channel systems, such as those transmitted through the data channel by using the RTS / CTS information float out from including Identifying the status of the node, ACK messages and data messages are different I to maximize the recognition. If the system uses a single channel, it may be conveyed by using an ACK message or a DATA message, corresponding information. A given load in the vicinity, the load conveyed, and by measuring the load of backlog, fairness of the use of the stream between the various nodes of the various links and various to be achieved, the algorithm, the channel · I adjust the access timer. Furthermore, by performing both to calculate the priority level based on the node queue state, of having to calculate the priority level based on the close state, the algorithm, service differentiation to break the contention layer It can be made possible.
