Abstract: Provided is a recording medium for storing a structure of a frame for performing Medium Access Control (MAC) and allocating resources in a multi-hop wireless Ad hoc network, and a method of performing Medium Access Control (MAC) and allocating resources in a multi-hop wireless Ad Hoc network. The method includes performing initialization of communication by receiving or transmitting a Request-To-Send (RTS) message and a Clear-To-Send (CTS) message from or to a node that is to be communicated with in the multi-hop wireless Ad hoc network; constructing a frame comprising at least one slot comprising an initialization field for performing the initialization of communication, a high level link region for communication between Full Function Device (FFD) nodes in the multi-hop wireless Ad hoc network which exist within a one-hop distance in the multi-hop wireless Ad hoc network, and a low level link region for communication between Reduced Function Device (RFD) nodes in the multi-hop wireless Ad hoc network which exist within a one-hop distance from the reference FFD node; allocating the resources to the frame on the basis of data types, priorities, and estimated interference values; and performing communication between nodes in the multi-hop wireless Ad hoc network within the length of the frame, and then returning to the operation of performing initialization of communication. Therefore, by effectively executing MAC and allocating resources according to a variety of data requests, it is possible to improve the reliability and Quality of Service (QoS) of the multi-hop wireless Ad hoc network and reduce power consumption.

The frequency hopping communication device includes a first frequency hopping unit for receiving data to be transmitted, orthogonal frequency division multiplexing (OFDM) modulating the received data using the frequency of a subcarrier corresponding to a first frequency hopping code among the frequencies of a predetermined number of subcarriers, and outputting first frequency hopped data on which the data to be transmitted is loaded and a second frequency hopping unit for second frequency hopping the first frequency hopped data by mixing the first frequency hopped data with a carrier composed according to a second frequency hopping code. When jamming occurs, the frequency affected by jamming is restricted to a narrow bandwidth. Therefore, it is possible to reduce the influence of jamming and to easily restore data even though jamming occurs. Also, it is possible to improve the degree of concealment of data.
