Method and system for controlling radio resource dynamic access in body area network simulation process

Abstract

The invention discloses a method and system for controlling radio resource dynamic access in the body area network simulation process. The method includes the steps that request information is received; priority is acquired from the request information; an initial value of a backoff counter is determined; when any windowing pull-up event occurs in the time slot cycle stopping period and the initial value is determined, whether a channel continues to meet all windowing conditions or not in a shortest interframe interval is judged, if yes, a time slot cycle is started, and if not, the time slot cycle is stopped; whether the channel meets all the windowing conditions or not when start monitoring time of each time slot is end is judged, if yes, 1 is subtracted from the number of the backoff counter, and if not, the time slot cycle is stopped; the time slot cycle is stopped when the number of the backoff counter becomes 0 through subtraction, a data sending command is sent out when a next time slot is started, and then data frames are sent to a physical layer through a transceiver. Simulation of media access control is separated from a simulation platform structure, and by the combination of a mechanism, for receiving and sending the data frames, provided by a simulation platform, body area network simulation is achieved.

Description

technical field [0001] The invention relates to the field of network simulation, in particular to a method and system for controlling dynamic access of wireless resources in body area network simulation. Background technique [0002] The wireless body area network is a wireless sensor network for monitoring human body conditions formed by self-organizing micro sensor nodes with low cost, low power consumption and capabilities of perception, data processing, storage and wireless communication. Wireless body area network is an emerging technology, its communication protocol is complex, and there are research requirements such as multi-network coexistence, multi-network integration, and multi-network interference. Therefore, how can researchers realize its complex medium access control (medium access control) in system simulation? , MAC) and wireless resource dynamic access control have become the focus and difficulty. [0003] The current body area network research does not h...
