Wireless sensor networks (WSN) have a great impact on most of the current applications, so great research efforts have been redirected in order to solve its problems. Some of the WSN applications are critical in which sensors energy is very important to be saved. Sensors might need to work effectively not for days but years. In addition, in some applications, sensors are left unattended and replacing the sensors batteries or even the sensors might not be possible, especially in hazardous and dangerous areas. Therefore, sensors energy has to be managed in a certain way to keep the overall network operating for a long time. Our contributions in this work are three-fold: 1) Introducing the concept multi-root tree to the WSNs to avoid nodes contention, 2) Proposing a new distributed algorithm based on the fuzzy logic controller to determine the status of each node dynamically based on the global network conditions, and the local nodes conditions, 3) Introducing a new mode of operation for the WSN node, which is the co-operative mode
