Extending Network Lifetime by Time-Constrained Data Aggregation in Wireless Sensor Networks

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 243)


The most important challenge in wireless sensor network is to reduce the energy consumption of each node and increase the network lifetime. Many networking schemes are used to minimize the amount of data transmission by data aggregation. Three main factors affecting the lifetime of sensor nodes are as follows: (1) the consumed energy for sending data from the leaves to the sink, (2) queuing delay during aggregation, and (3) the tree’s delay, which is equal to the tree’s depth, should be considered. We analyze the optimal time allotted for intermediate node data aggregation and optimal delay at each higher aggregation node. The adaptive scheme then dynamically adjusts the time constrain at the sensor node.
