Abstract
A method, apparatus, system, and computer program product example embodiments of the invention are disclosed to structure access to a wireless medium to reduce interference between nearby nodes. In example embodiments of the invention, a method includes the steps of determining an amount of available wireless communication resources in a reception area; determining a number of wireless communication nodes in the reception area; generating a reservation limit of the available wireless resources; determining an inability to allocate the reservation limit of the available wireless resources; transmitting a request for release of resources to at least one other wireless communication node. Another node receiving the request, performs a method including the steps of determining a threshold; comparing an allocated amount of wireless communication resources against the threshold; and releasing at least a part of the allocated amount of resources, if the reserved number is greater than the threshold.
