Abstract-This paper proposes LBA, a lifetime balanced data aggregation scheme for asynchronous and duty cycle sensor networks under an application-specific requirement of end-to-end data delivery delay bound. In contrast to existing aggregation schemes that focus on reducing the energy consumption and extending the operational lifetime of each individual node, LBA has a unique design goal to balance the nodal lifetime and thus prolong the network lifetime more effectively. To achieve this goal in a distributed manner, LBA adaptively adjusts the aggregation holding time between neighboring nodes to balance their nodal lifetime; as such balancing take place in all neighborhoods, nodes in the entire network can gradually adjust their nodal lifetime towards the globally balanced status. Experimental studies on a sensor network testbed shows that LBA can achieve the design goal, yield longer network lifetime than other non-adaptive and nodal lifetime-unaware data aggregation schemes, and approach the theoretical upperbound performance, especially when nodes have highly different nodal lifetime.
Finally, in REF , a lifetime balanced data aggregation scheme for asynchronous and duty cycle sensor networks is presented, which dynamically adjusts the aggregation holding time between two neighboring nodes and hence balances their nodal lifetime.
