Abstract: 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.

Abstract: A wireless communication device providing a node in the network includes a wireless transmitter, a wireless receiver, a transmission buffer, and a packet prioritizing unit configured to obtain data relating to packets to be transmitted in the network, obtain indications of the remaining lifetime of the packets, where the indications are based on the time needed for reaching a destination node, prioritize the packets according to the remaining life time indications, where the prioritization is made in ascending order from an indication of a low remaining life time to a high remaining lifetime, and place the packets in the transmission buffer for transmission according to the prioritization.
