Snoop based group communication scheme in cellular Machine-to-Machine communications

Abstract

Machine-to-Machine (M2M)communication is expected to be one of major communication methods in the future. In M2M communications, there are important requirements: extremely low power consumption of devices and mass device transmission. In order to meet the requirements, a novel snoop based relaying method in cellular M2M communications is proposed in this paper. The proposed scheme consists of two steps: 1. snooping group formation including group head selection and group members assignment based on link quality or location, 2 snooping and relaying packets to/from group members. By employing the proposed scheme, efficient M2M communication can be achieved without changing physical layer of wireless communication standards while meeting the requirements of extremely low power consumption and mass device transmission.
