| Summary: | One class of Vehicular Delay-Tolerant Networks consists of two node types: stationary and mobile. Stationary nodes deployed along roadsides cannot directly communicate as they are considerably distant. Mobile nodes mounted over vehicles opportunistically entering the range of a stationary source serve as relays that carry bundles to the destination. In this letter, we introduce a novel relaying scheme that probabilistically determines a vehicle's suitability to carry bundles. Hence, bundles are released to a present vehicle if and only if that latter contributes in minimizing the mean transit delay. Extensive simulations were performed to gauge the merit of the proposed scheme. |
