Wireless sensor networks are continuing to receive considerable research interest. The energy constraint inherent in the small battery powered nodes presents a considerable problem, and much effort is being put into reducing the power consumption. In this paper, we introduce IDEALS (Information manageD Energy Aware aLgorithm for Sensor networks), which aims to extend the network lifetime for important messages. This is obtained through the possible loss of low importance messages. IDEALS is fundamentally built upon a concept of message and power priorities, and is particularly relevant for energy harvesting nodes. The results obtained from a developed simulator show that considerable advantages can be obtained from IDEALS.
