In this work, we focus on real-time routing in Wireless Sensor Networks (WSN) and the Prolongation of their operational lifetime. Specifically, we aim to find a solution that minimizes energy consumption in WSNs as well as data collection delays. To address this issue, we proposed a new protocol named ERRMS, which stands for « Energy-efficient Real-time Routing Mobile-Sink based». ERRMS is based on another protocol called EDEDA, which relies on a fixed path mobile sink approach. We worked on application scenarios with periodic data collection and made improvements in the selection of rendezvous points (RP) to minimize their number. This reduces the travel time required for the mobile sink to collect data from all the sensor nodes in the network, thereby reducing the collection delay for real-time communication. Our solution was validated through simulation using the NS-3 simulator. Both our protocol and EDEDA were integrated into the simulator. The results obtained from various experiments are presented in the form of graphs and snapshots, showing extremely positive outcomes.
