### Comparison of PARSLAD Performance in Three Scenarios
\begin{table}
\begin{tabular}{c c c c} \hline \hline
**Description** & **Base Scenario** & **Manually Controlled Scenario** & **Smart Scenario** \\ \hline Bulb operation state & ON and OFF. & ON and OFF. & ON, DIM and OFF. \\ \hline \multirow{4}{*}{Environment of scenario} & The light bulb is always in ON state in the evening and night time. This can be compared to public outdoor environment scenario. & The light bulb is turned to ON state when obstacle reaches and then is switched off. This takes place in indoor environment and in private outdoor environment (e.g.: Terrace, parking areas and garden in homes.) & In indoor, public and private out door environments. \\ \hline Control of Light bulbs & Centralized control. & Distributed or Decentralized control. & Both Centralized and Decentralized control. \\ \hline \multirow{4}{*}{Example of scenario} & Currently, the street lights in developing countries are ON even if there is no vehicle or obstacle movement. Emergency corridors and staircase two have ON Light bulbs. & In home switches turn on the light when needed and then turns OFF manually. & In all types of environment, the light is in ON or DMI state based on the motion sensing and daylight illuminance value. \\ \hline \multirow{4}{*}{Advantage and Disadvantage} & Though the street light in ON condition throughout in the evening and night time is beneficiary in highways as it is always busy. The criteria is also followed in rare streets in village as the street lights are controlled centrally. This leads to unnecessary power consumption. Even in the case of presence of partial sunlight at sun rising and setting time operation is not possible. So light should be either ON or OFF. & The light is OFF when there is no intervention. Even in centralized control, outdoor environments, only the lights near the obstacle intervention is in ON or DMI mode and other light bulbs are in OFF state. In case of partial daylight, illuminance light is operated in DIM state on the detection of motion. In indoor environment, if the light is not for profitfulness of inhabitants the PARSLAD device switches to OFF state. Further this system uses alert control mode to surveillance the nearby areas of light buls and alert the surrounding. On future expansion of alert mode with GSM and camera facility will lead to enhanced surveillance and lighting control in one structure. \\ \hline \hline \end{tabular}

Table 8: Explanation of the three scenarios. PARSLAD with the 8 W LED bulb gives 57.5% and 15% of energy consumption reduction in comparison to the base and manually controlled scenario, respectively. Thus, the device works efficiently and the proposed proposed approach. \begin{table}
