References	Algorithm/method	Problem discussed	Benefit/achievement	Drawback/limitation
[20]	Optimal decision rule	Selection of the bridge node in the virtual sensor network	Reduces the energy consumption of every node	Heterogeneity and node mobility are yet to be considered
[21]	Customizable sensor information system	To modify the transmission of data and frequency of data collection	Energy efficient and reduces the emission of CO2	Not scalable
[22]	Wireless energy transfer	Energy harvesting and deadline constraints	Less energy consumption	Does not support multitasking
[23]	Pull-push communication	Sensor and cloud integration	Less bandwidth consumption, energy efficient, and collects more data	Does not support QoS
[24]	Compression algorithm	Reduction of replicated data	Transmission energy is minimized	Data prediction is yet to be implemented
