Most of the power allocation schemes rely on centralized server to resolve resource allocation problem, provided the server must have a global knowledge about the channel state information and interference information of every receiver. Due to this, computational ability of server becomes tedious as it create interference to other secondary users. This paper is to allocate power for secondary users in distributed manner using frequency division multiplexing access within the node power budget. A power allocation algorithm is proposed to maximize throughput of secondary users by calculating pay off function.
