Résumé:
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.
