Anchor-based Group Relay MAC

The world moves into a new era with the advent of the Internet of Things (IoT). This technology changes many things from daily life to society as a whole. To use the technology, data are the fundamental factors. If more sensor data is generated, more information or more specific information can be provided to people. Some of the technologies for collecting data are the various Medium Access Control (MAC) protocols. Especially for the IoT System, the Wireless Sensor Network (WSN) MAC protocols have been proposed among the MAC protocols. However, even among the WSN MAC protocols, there are many of them. Each of them has its own characteristics. Some of them depend on the places where the MAC protocol operates. Previously, WSN is usually composed of the stationary sensors. This static environment has changed as the technologies are advanced in many ways. Not only is it possible for sensors to move around, but sinks can also move around. In real life, these various sensors are mixed. Thus, MAC protocols for WSN with stationary sensors and mobile sensors are needed. In this paper, we propose an Anchor-based Group Relay-MAC (AGR-MAC) for the WSN with mixed sensors.
