Energy-efficient smart retail system design is a challenging research area. In this paper, we propose an automated retail system using a femtolet-based fog network. A femtolet is an indoor base station providing computation and storage. Femtolets in our system work as indoor base stations and maintain databases of the products located in their respective coverage areas. The femtolets switch to active or idle mode according to the user's presence in its coverage. A smart trolley is proposed for our retailing system, which guides the user to the particular product type selected by the user. The user, after entering the shopping mall, carries the smart trolley. The customer selects and purchases products using this trolley. On the basis of product purchasing, the respective databases maintained inside the femtolets are updated. An Android application for the proposed retailing is developed. We compare the power consumption and delay of the proposed retail system with the existing retail system. Simulation analyses illustrate that the proposed approach reduces power by approximately 89% and 94%, respectively, in comparison to the local cloud server-based and remote cloud server-based retail systems. Thus, we refer to the proposed system as a green retail system. The performance of the proposed system through experimental analysis is also evaluated.

“…It is an indoor base station containing large storage and having processing power. The femtolet contains the components of a femtocell and a cloudlet, and it has the features of both. A femtocell is a home node base station (HNB) with low transmission power, and it is used for providing a good signal level at the indoor region .…”

Mobile devices have become an essential part of our daily life. Different types of cellular networks exist for providing service to the mobile users. GSM is the first mobile communication system which raises the popularity of mobile services. After GSM, other kinds of wireless communication systems come into the scenario such as WCDMA, LTE etc. Each of these systems has their own pros and cons. In this paper we have performed a comparative signal analysis between these popular networks considering noise effect, bandwidth, and power using vector signal generator to draw a conclusion on their effective deployment in different scenarios. The power transmission by the base stations in an area covered by GSM, WCDMA and LTE network based on user density is determined and compared with the same using only GSM network. Simulation results present that using proposed deployment scenario 10.22-17.5% reduction in power transmission is achieved and hence it is referred as a green network.

“…The primary goal of sensor cloud is to facilitate the connection of sensors, people and software objects to build community-centric sensing applications. Incorporation of mobile devices like mobile phones, laptops, tablets into CC introduces mobile CC (MCC) [12][13][14]. In this paper, the architecture of green sensor MCC (SMCC) is proposed as an integration of WSN, mobile network and CC with simulation and experimental analysis.…”

This study presents an architecture of green sensor mobile cloud computing which integrates sensor network and mobile network with cloud computing. In the proposed scheme, the sensor data are transmitted to the cloud through a mobile device. To develop the proposed architecture both the indoor and outdoor region are considered. For indoor region light weight access point and home node base station are used by the mobile device for sensor data transmission to the cloud, whereas for outdoor region macrocell and microcell base stations are used. Simulation results present that using home node base station the power consumption at indoor region can be reduced by ∼10% than the light weight access point, and using microcell base station at outdoor region the power consumption can be reduced by ∼30% than the macrocell base station. Hence, using home node base station and microcell base station green sensor mobile cloud computing can be obtained at indoor and outdoor regions, respectively. In this study, an experimental analysis of the proposed architecture is also performed.
