Abstract
A communication method in a wireless sensor system of networks served by a first non-beacon mode coordinator and a second beacon-mode coordinator, initially, placing all network devices in a first network of the first coordinator; monitoring a parameter of each entity by sensors of the network devices; transmitting sensor data from the network devices in the first network to the first coordinator; detecting an emergency state with respect by using the monitored parameters; in response to detection of the state, handing over the network devices to the second network; transmitting sensor data from the network devices in the second network to the second coordinator; and in response to detection of the emergency state, handing over the associated network devices to the first network.
