M2M Gateway Selection Scheme for Smart Wireless Devices: An Energy Consumption Perspective

Wireless standardization activities such as Bluetooth V4.x have led to an explosive growth in innovative short-range wireless devices capable of providing various services to assist everyday life. Allowing Machine-to-Machine (M2M) communication between these M2M devices also enable new commercial service opportunities. Typically, short range M2M devices need another capable device such as a smartphone to act as a gateway (GW) to connect to the Internet to operate at its full potential. We investigate an architecture where any Internet enabled device in the wireless range acts as an M2M GW for M2M devices. This eliminates the need for the M2M device user to also own an Internet enabled device to obtain services such as Online-to-Offline. This scheme faces new challenges such as, how to identify a best M2M GW for a required service and QoS. This paper investigates the performance of M2M GW selection schemes in terms of energy consumption using real world data collected at an exhibition with encouraging results.
