  • Publication number: 20070121545
    Abstract: A method of resource allocation among mobile stations in distributed communication network enables a mobile station to perceive existence of another mobile station through a time slot for resource allocation without having to communicate with a sensor node. If perceiving another mobile station, the mobile station allocates time slot resources not to overlap with the time slot resources of another mobile station, and performs location measurement or media access and reception of service from the sensor node through the allocated time slot resources. Because the mobile stations of the network can perceive each other by communicating with each other, and accordingly allocate their own resources without overlapping with the resource of the others, frequent collision of the signal for location measurement can be prevented.
