An optimized dynamic fair resource allocation technique in a femtocell



Mobile application usage has grown tremendously over the past few years. This is as a result of increased user tool applications that require multiple bit streams from the mobile providers. These applications therefore tend to make it necessary to look into ways of optimizing on the resources allocation to users in order to accommodate these increasing requests.
In this paper, two techniques that allocate resources to users based on their requests are analyzed. These are Global mobility prediction under the mobility aware algorithm and the proposed Combinational allocation of resources requests to users, in priority order of Signal to Interference plus noise ratio (SINR) values. The combinational scheme also incorporates fairness in resource allocation by considering the low-SINR valued users who have been left out and reallocating them a resource from the next low-SINR valued users to enable all users communicate in the femtocell. Examples of users who are positioned in groups of 4 inside a femtocell at 8 different time snapshots: A to H, are carried out using the two algorithms: Global mobility prediction and Combinational allocation scheme. They are simulated using MATLAB and plots done to determine the best SINR total groups for the combinational scheme and graphical plots drawn from the tabulated results.
The findings of the simulations done show that the combinational approach yields higher SINR totals and also ensures that all users are able to communicate due to the fairness consideration to the low SINR valued users. The combinational scheme also utilizes fairness in resource allocation by considering the low-SINR valued users who are reallocated a resource from the next users with the next low-SINR values. This ensures that all users who request for resources communicate in the femtocell. The global prediction on the other hand allocates resources in the sequence provided and hence results in some users being left out and also low SINR totals for users. Hence higher throughput is realized using the combinational allocation scheme.
