Abstract

The availability of adequate resources will always remain  to be  a concern for mobile network operators. Therefore, for Orthogonal Frequency Division Multiple Access (OFDMA)  networks, factors such as Signal to Interference plus Noise Ratio (SINR) and resource capacity continue to be feasible areas of research. A combination resource allocation  with fairness control  is hereby explored with reference to users’ individual requests for resources at a given femtocell being taken into account. In addition, their signal to noise ratios is calculated alongside serialized users’requests per individual. This chooses the users with best SINR values with a given resource allocation to each user.An example of 3 users is considered with the resource requests and SINR values as follows: user 1 requests for 3 resources and has 5dB, user 2 requests for 2 resources and has 7 Decibels (dB) and user 3 requests  for 4 resourcesand has4dB. The total requests are 9 resources and only 5 are available. When the  combination is  applied it determines that the best allocation would be as follows:  user 1 to be allocated 3 resources and user 2 to be allocated 2 resources. The fairness scheme then allocates a resource to user 3  by deducting one from user 1  to enable him to communicate through the femtocell.
