But the high number of small cells and their low coverage involve more Handovers to provide continuous connectivity, and the selection, quickly and at low energy cost, of the appropriate one in the vicinity of thousands is also a key problem. In this paper, we propose a new method, to have an efficient, blind and rapid handover just by analysing received signal probability density function instead of demodulating and analysing received signal itself as in classical handover. The proposed method exploits kullback leibler distance (KLD), akaike information criterion (AIC) and akaike weights, in order to decide blindly the best handover and the best base station (BS) for each user.

The exponentially increasing demand for wireless data services [2] require a massive network densification that is neither economically nor ecologically viable with current cellular system architectures. Fifth Generation (5G) [3-4] have recently emerged to satisfy the increasing demand for high data bit rates. A crucial requirement for 5G networks is the deployment of Small Cells (SCs) [5] over Macrocells layer which introduces a new type of networks called Heterogeneous Networks (HetNets) [6]. A HetNet is simply the banding together of different sized cells to provide ultra dense coverage in defined geographic areas. Small Cells (SCs) are low-powered cellular radio access nodes that operate in licensed and unlicensed spectrum that have a range of 10 meters to a few kilometers. They will be a crucial component of 5G networks, because they have the ability to significantly increase network capacity, density and coverage, especially indoors. They are a relatively low cost deployment option and, because they are low power devices [7], are relatively cheap and efficient to run to give a low total cost of ownership. Like every other technology, SCs have some drawbacks that give rise to some major concern on part of the end users. In this paper, we are going to study the problem of the management of handovers. Handover is the practice of retaining a user’s active connection when a mobile terminal changes its connection point to the access network (called “point of attachment”) [8-9]. Because of the low coverage of SCs, it is essential to Journal homepage: http://ijai.iaescore.com
