1. A method for providing low complexity dynamic persistence for random access in a wireless communication system, comprising the steps of:

  • A) registering, by an access point device, a plurality of peripheral devices;

    B) determining, by the access point device, a persistence level based on a number of peripherals in the plurality of peripheral devices;

    C) setting, by the access point device, a source address within a block assignment to a contention address and the persistence level;

    D) broadcasting, by the access point device, the block assignment;

    E) identifying, by each peripheral device, the contention address and reading the persistence level;

    F) generating, by each peripheral device, a random number based on the persistence level;

    G) determining, by each peripheral device, whether the random number is equal to zero;

    H) transmitting, by any peripheral device for which the random number is equal to zero, a payload burst containing a resource request;

    I) deferring transmission of a payload burst, by any peripheral for which the random number fails to equal zero;

    J) receiving a payload burst, by the access point device; and

    K) acknowledging, by the access point, reception of the payload burst and which peripheral device transmitted the payload burst.
