| Summary: | The problem of load imbalance in HetNets among wireless access technologies is addressed in this
article. A two-step strategy algorithm was adopted in this work, which considers both load and bandwidth. The first
step is a randomized algorithm based on the Monte Carlo scheduling strategy while the second step was a load
leveling algorithm that used the brute force method to classify the load on access technologies as average, below
average and above average. The obtained results when compared to those of Least Connected Algorithm (LCA)
performed better. The results achieved a global load balancing fairness of 0.9119 which was 12.37% better than
LCA. The significance of the achieved result translates to better resource utilization among the wireless access
technologies and better Quality of Service (QoS) for users. |
