Wireless sensor networks (WSNs) are often used for monitoring environmental conditions. One of the most important tasks in a WSN is to gather sensed data for the users to utilize the network with adequate flexibility. In this process, it is also very important to employ energy-efficient communication protocols since sensor nodes are usually battery-powered and hence their lifetimes are relatively short. Considering these practical aspects of WSN deployment for various types of application scenarios, in this paper, we propose a data query dissemination scheme and data gathering solution. By considering energy conservation and latency, we provide parameterized query which can be adapted according to the user’s profile to collect the required readings from sensor nodes. Simulation results prove that the proposed protocol is more energy-efficient compared to the other alternatives of the same kind.
