Abstract

A system method for transmitting / receiving frames of a MAC (Medium Access Control) protocol layer module that processes data frames and control frames transferred from a MANET (Mobile Ad Hoc Network) protocol layer module in a station receiving frames transmitted through a MANET including a plurality of stations. The method comprises: (1) distinguishing between control frames and data frames in analyzing frames transferred from the MANET protocol layer module; (2) providing the control frames with higher priority than the data frames so that the control frames firstly preempt a medium earlier than the data frames; and (3) transmitting the control frames and the data frames in order according to their respective priorities. By the construction, the control frames are processed first in preempting a medium, before the data frames, in the MAC layer of a station in which the MANET exists, thereby preventing the data loss caused by transmitting the data frames first.

Description

technical field [0001] The present invention relates to a mobile ad hoc network (MANET) in which a network is formed by a plurality of mobile stations (hereinafter referred to as "stations"), and more particularly to media access of stations in the MANET Control (MAC) protocol layer components and methods for transmitting / receiving frames of MAC protocol block components. Background technique [0002] MANET is an unstructured network without fixed routers, hosts and wireless base stations. In MANET, mobile nodes are connected by using multi-hopping for classes. The topological structure of MANET can be changed dynamically and the network has self-forming and self-restoring functions. Since it is not a network in which only fixed base stations can provide mobile services, each node itself can form a network routing architecture in a special form and each node included in MANET can move automatically. Therefore, MANET uses a protocol that can be adapted to structural change...
