Abstract

With the increase in the number of wireless end users, the demand for high-speed wireless network has increased by multiple folds. Moreover, most of the data traffic is observed to be generated from the indoor environment. Hence, researchers have come up with the solution of deploying Small Base Stations (SBSs) in the indoor environment, which proves to be immensely effective in providing the last mile connectivity. However, since the deployment of the SBSs is unplanned, there exists a high chance of co-tier interference, which might be mitigated by transmission power control but at the cost of degraded quality of service for some of the end users. Hence, in this work, we propose the concept of mobile SBSs which are connected to power grids located in the ceiling of the deployment region. The mobile SBSs position themselves at the received signal strength-based centroids of the end user clusters, thereby mitigating the co-tier interference as well as conserving power of the handsets by minimizing the distance between the SBS and the end-user handsets. To enhance the security of the system, the SBSs are considered to form a closed group. The proposed system requires about 13% lesser number of SBSs while enhancing the end-user coverage by 9.3%. Moreover, about 10% improvement has been observed in terms of cumulative throughput for mobile SBSs compared to fixed SBSs. Thus, the deployment of mobile SBSs proves to be more effective compared to the fixed SBSs for indoor communication.
