Method for granting medium access in a wireless network and network therefor

摘要

The present invention relates to a method for granting medium access to a node in a wireless network, the network comprising at least two nodes, and the method comprising the step of determining, for one of the at least two nodes, a medium access rate to be used, a medium access rate determining how often a node transmits data throughout the network, wherein the rate is determined as being different from one node to another and dependent on the number of neighbors of a node. The invention also relates to a wireless radio network comprising at least two nodes, wherein a medium access rate to be used by a node is determined as being different from one node to another and dependent on the number of neighbors of a node, a medium access rate determining how often a node transmits data throughout the network.

1. A method for granting medium access to a node in a wireless network, the network comprising at least two nodes, and the method comprising:
determining, for one node of the at least two nodes, a medium access rate to be used, the medium access rate determining how often a node senses the medium in order to transmit data throughout the network; each node determining a number of nodes of the network in its carrier sense range; distributing a minimum number of nodes in the carrier sense range of any node in the network; wherein the medium access rate for the one node is determined as being different from the medium access rate for each of the remaining nodes in the network and dependent on a number of nodes of the network in a carrier sense range of the one node; and based on the distributed minimum number of nodes, determining, for each node of the network, the respective medium access rate to be used, wherein the medium access rate to be used by each node is calculated as follows:
medium access rate of node i=σ(1+σ)γ(i)−γ*,wherein σ is a positive quantity corresponding to a basic access rate, γ(i) is the number of nodes in the carrier sense range of node i, and γ* is the minimum number of nodes in the carrier sense range of any node in the network.
