Method and apparatus for a hybrid limited contention and polling protocol

摘要

An apparatus and method to implement a hybrid contention and polling protocol for a communications or computer network is disclosed. Various apparatus and method embodiments of the invention employ specific polls from a primary station for polling identified secondary stations of the network which may be in an active state; limited contention polls to an identified individual secondary station which may be in an idle state or to an identified subset of a plurality of secondary stations which may be in an idle state to initiate limited contention access to the network; limited contention polls for collision resolution in the event that a plurality of secondary stations in an idle state may have simultaneously contended for network access; general polls to any of a plurality of secondary stations of the network which may be in an unresponsive state to initiate contention access to the network; and general polls for collision resolution in the event that a plurality of secondary stations may simultaneously contend for network access. Various embodiments may also include frequency channel allocation for transmission and reception of data and other information within the network.
