Many researchers proved that Wireless Sensor Networks (WSN) is one of the most overwhelming technologies for meters information collection systems. In this research, we proposed a network design for the WSN to collect the electric meters information in Jableh city-Syria using mobile gateway. We improved the performance of IEEE 802.15.4 protocol using Guaranteed Time slots (GTS) according to our application need. WE also deduced the mathematical equations that describe the protocol and thus we could get pre-simulation results. We used NS 2.35 and SUMO 0.32.0, and we found that by choosing the appropriate values for the protocol parameters according to our network design and method of collection, we could achieve the reliable collection of electric meters for a gateway speed of up to 70 Km/h which is considered an improvement of the protocol performance compared to other literature studies. 2023 08 22 2136 https://creativecommons.org/licenses/by/4.0/ 10.54216/PMTCS.020201 https://www.americaspg.com/journal/40/article/2136 https://www.americaspg.com/storage/91696388674.pdf
