METHODS IN WIRELESS BODY AREA NETWORKS AND A HUB FOR A WIRELESS BODY AREA NETWORK

摘要

According to one embodiment is a method in a hub of a first wireless body area network (WBAN). The first WBAN includes the hub and at least one sensor node. The hub is configured to wirelessly communicate with the at least one sensor node on a first frequency channel and the method comprises: receiving a retention index of a second WBAN operating on the first frequency channel, wherein a retention index is a measure of the operational characteristics of the respective WBAN; comparing the retention index of the second WBAN with a retention index of the first WBAN; and changing the wireless communication behaviour of the first WBAN if the retention index of the first WBAN is lower than the retention index of the second WBAN.
