MAIN HUB, SUB HUB, AND SENSOR NODE COMMUNICATING IN WIRELESS BODY AREA NETWORK (WBAN) INCLUDING AT LEAST ONE SUB HUB, AND COMMUNICATION METHOD THEREOF
First Claim
1. A communication method of a main hub in a wireless body area network (WBAN) comprising the main hub, a sub hub, and a sensor node, the method comprising:
- assigning a beacon slot to the sub hub;
receiving, from the sub hub, a beacon signal based on the beacon slot;
verifying whether the sub hub comprises data to be transmitted to the main hub based on the beacon signal; and
receiving, from the sub hub, the data based on a result of the verification.

Abstract
A main hub, a sub hub, and a sensor node communicating in a wireless body area network (WBAN) including at least one sub hub, and a communication method thereof, are provided. A communication method of the main hub, includes assigning a beacon slot to the sub hub. The method further includes receiving, from the sub hub, a beacon signal based on the beacon slot. The method further includes verifying whether the sub hub includes data to be transmitted to the main hub based on the beacon signal. The method further includes receiving, from the sub hub, the data based on a result of the verification.
