  • Abstract Mobile communication is important and the trend of future. Homogeneous networks are used by 2G and 3G. Heterogeneous networks are introduced to cellular systems to enhance coverage, save energy, reduce budget and improve capacity. Deploy different kind of Base Station is profitable. The problem of base station deployment has proven to be NP-hard. An excellent planning can improve network performance effectively. In addition, energy saving is an important issue along with the increase of network traffic as well as limited resources.
    Many researches deploys the Macro-cell and small-cell in the environment simultaneously. However, in most cases, when the provider deploys the small-cell for network enhancement, they add the small-cell into an environment which has had several Macro-cell. As mentioned above, because of those reason, we focus on adding the small-cell flexibly with budgeted cell planning. We take into account the UE location and different base station and proposed the algorithm which combine K-Means and MDBSCA to achieve the objective of high-satisfied rate. Moreover, we adjust the power emission to attain the target of low power consumption and high-energy efficiency.
    The performance improvement of the proposed algorithm has been validated by simulation result. Compare with K-means and DBSCAN, the proposed method can decrease the power consumption by 34% at most. In regards to UE satisfied ratio, the improved rate is 36% at most. The utilized rate rise to 75% at best in terms of energy efficiency.
