• Nowadays, there has been skyrocketing demand in data surge. Therefore, there is need of massive network densification along with various technological advancements to meet the demand. Deploying macro cells to meet these demands is not economically viable due to high capital and operational cost. Therefore, operators would be deploying dense small cell networks to meet these demands. Small cell has issues of interference and mobility management. We were targeting to sort out the mobility management issue by exploring the techniques of coordination among small cells and predicting the cells in advance for optimal resource management. For this, an optimization problem was formulated and solved using cplex tool.
