MoM - a real time monitoring and management tool to improve the performance of Vehicular Delay Tolerant Networks

Abstract

Vehicular Delay Tolerant Networks (VDTNs) appears as an innovative approach to deal with several issues faced by vehicular communications. By exploiting vehicles and deploying a DTN store-carry-and-forward paradigm with an Internet protocol over VDTN it is possible to enable asynchronous communications in the absence of end-to-end links. VDTNs also combine a bundle-oriented communication with an out-of-band signaling approach. To ensure that network nodes follow the protocol contributing to the welfare of the network, network monitoring and management functions play a key role. This paper proposes and describes a monitoring and management tool for VDTNs, called MoM, which collects real-time information from the network in order to improve the overall network performance. Conducted studies shown that MoM contributes to increase the bundle delivery probability and decreases the amount of wasted resources.
