Green Handover with a Hybrid Satisfaction Mechanism

Green communications have emerged as one of the most important trends in wireless communications because of its several advantages of interference reduction, battery life increase and electrical bill cut. Its application to handover mechanisms is a crucial operation for its integration in practical systems, as handover is one of the most resource-consuming operations in the system, and it has to be optimized under the objective of green communications. On the other hand, a decrease in the energy consumption should not mean lower performance for the operator and customers. Therefore, this paper will present a hybrid handover mechanism where two conflict objectives of load balancing and energy consumption are tackled, where the operator'[s objective is to balance the data load among its macroand small-cells, while the user equipment objective is to decrease the consumed energy in order to guarantee a larger battery life. Interesting conclusions are obtained about the presented approach through computer simulations.
