1. A method of joining a first device and a second device with a network, the method comprising:
joining a first device with the network and subsequently joining a second device with the network, wherein a priority level for joining with the network associated with the first device is higher than a priority level for joining with the network associated with the second device, and the joining step further comprises sending, from the first device a first registration request to a registration apparatus that registers devices on the network, and sending, from the second device, a second registration request to the registration apparatus;
applying a first waiting period, being one of a back-off time period and a retry time period, to the first registration request, the first waiting period being shorter than a second waiting period applied to the second registration request;
setting respective upper and lower boundaries for the first waiting period and the second waiting period, in accordance with the priority level associated with the first and second devices;
randomly generating a first waiting time within the first waiting period; and
changing the upper and lower boundaries of the first waiting period for each subsequent retry attempt,
wherein the method further comprises storing the priority level of the first device within the first device and storing the priority level of the second device within the second device, and storing a table indicating both the first waiting period and the second waiting period in both of the first and second devices.
