A resource allocation method for performing resource competition between protocols based on a protocol in a home network environment using multiple protocols is provided. In the resource allocation method, a request of using a resource is received from an external device. An AIFS value is allocated according to a data type of the resource requested from the device. Then, the resource is not provided to the device for an AIFS period. After passing the period of the AIFS value, a back-off timer period is entered. In the back-off timer period, an application protocol of the external device requesting the resource is identified, and an idle time value is allocated according to a type of the identified protocol. Then, a corresponding resource is provided to the first device coming out of the allocated idle time.
