Nowadays, the emerging hyper-dense heterogeneous network (HetNet) is an effective solution to building an easy-Access wireless communication environment. In the hyper-dense HetNet, however, the inescapable handoff procedure is the key to its success. An effective handoff algorithm can not only achieve the goal of load-balancing but also enhance the overall system capacity. In this paper, we proposed an efficient load-Aware vertical handoff (VHO) algorithm for HetNets. With the aid of the system load information from the neighboring cells, the computational complexity during the VHO procedure can be significantly reduced. Moreover, by effectively off-loading the cells with relatively light traffic loads (i.e. non-worst conditioned cells), the dropping rate can be significantly reduced. Most importantly, the user and the overall system capacity can be greatly enhanced as well.
