Group Polling Method for Sensors Detecting in Unsynchronized Structured Wireless Monitoring Networks

Ivan Tsitovich
It is investigated the problem of detecting alarming sensors in large monitoring networks when there are objects where sensors can activate alarming signals simultaneously. We propose a generalization of the method of a sensor signal coding for an alarm signalization when a sensor signal can not be synchronized in time. This method bases on the method of group polling for alarming sensors identification for a synchronized network and has similar characteristics of complexity. Our methods has more complicated structure than previous ones. For a network with very large object we propose to use a sub-network of sensors at the object based on the Wi-Fi HaLow technology. For a network with middle size objects it is proposed the method with synchronized in time sensors at every object.
