摘要： A method for maintaining network lifetime of a wireless network in wireless communication system, the network including a plurality of device nodes. Selected ones of the wireless nodes have assigned roles in the wireless network. To improve and maintain network lifetime the method includes determining a below threshold operating condition of a first sensor node assigned to a first role and re-assigning the first role to another second node in said network. In other aspects of the invention a method, system and a computer program for carrying out the method are described.

摘要： A method for localizing a node in a wireless network, the method including: receiving location signals transmitted by beacons, the location signals including information about the locations of the respective beacons; detecting the respective received signal strengths of the received location signals; obtaining information about the different signal levels at which the beacons can transmit; studying the received location signals; determining the signal levels used by each of the beacons for the transmission of the location signals, based on the studying of the received signals; calculating a distance to each of the beacons based on the detected signal strengths and the determined signal levels; and localizing the node by means of the received location information and the calculated distances. The invention also relates to a node ant to a wireless network.
