Abstract
A system and method for data collision resolution wherein the same back-off window is sent to a plurality of remote users and is recalculated to maintain a constant collision rate and thereby increase throughput. The collision rate of the network is estimated in the present invention by detecting collisions in reservation slots and the size of the back-off window is adjusted to maintain a collision rate of approximately 1−2/e.
Claims19
A method for resolving data collision in a network shared by a plurality of users, the method comprising:
- sending a first back-off window to more than one of the plurality of users of the network;
- calculating a second back-off window based on at least one operational characteristic of the network;
- and
- sending the second back-off window to more than one of the plurality of users of the network.
A method for resolving data collision in a shared network, the method comprising:
- sending a common back-off window to a plurality of users of the network;
- and
- recalculating and sending new back-off windows to at least some of the plurality of users to increase throughput of the network.
A system for resolving data collisions in a shared network, comprising:
- a plurality of remote devices;
- and
- an access point in communication with the plurality of remote devices, wherein the access point further comprises:
- a switch for communicating with the plurality of remote devices;
- a transceiver for sending information to and receiving information from the plurality of remote devices;
- and
- a collision resolution device that calculates an initial back-off window to be sent to the plurality of remote devices and dynamically adjusts a back-off window to substantially maintain a predetermined constant collision rate.
