“…Max-Util [27] is a utility based algorithm proposed in this paper whereas their routing decisions are based on parameters like destination utility, relay utility, buffer utility, contact, and overall utility. There is another paper [28] which is related to network management, the network is managed by selecting the managers who are stable nodes. A priority-based scheduling and drop policy are proposed in this paper [29] along with a hybrid routing algorithm that routes messages which are scheduled built on priorities.…”

Vehicular delay tolerant network (VDTN) is a widely used communication standard for the scenarios where no end to end path is available between nodes. Data is sent from one node to another node using routing protocols of VDTN. These routing protocols use different decision metrics. Based on these metrics, it is chosen whether to send data to connected node or find another suitable candidate. These metrices are Time to live (TTL), geographical information, destination utility, relay utility, meeting prediction, total and remaining buffer size and many other. Different routing protocols use a different combination of metrics. In this paper, a metric called "estimation-time" is introduced. The "estimation-time" is assessed at the encounter of two nodes. Nodes may decide based on that whether to send data or not. This metric can be used in routing decisions. The simulations results are above 88% which proves "estimationtime" metric is calculated correctly.

“…Another approach is to use in DTNs a management protocol that is tailored to the environment with high delays and packet loss and to guarantee interoperability with Internet management protocols, such as SNMP. Salvador, Macedo, and Nogueira present the HiErarchical MANagement (HE-MAN) architecture [27,28] for Vehicular Delay-Tolerant Network (VDTN) environment. In the architecture, nodes that are close to each other are clustered together and managed locally using SNMP.…”

Network management in Delay/Disruption Tolerant Networks (DTNs) is an active research topic and covers topics such as system architecture, roles of actors, and management protocol. The existing solutions either expect a flat management hierarchy or do not address the hierarchical structure used in management. However, in many real-world DTN use cases, particularly in emergency and military contexts, the actors using the DTN system are a part of an organizational or operational hierarchy, and the network design and topology follow the hierarchical structure. This paper introduces a DTN management scheme that is based on that hierarchy. The paper presents a node categorization that is based on the hierarchy, the characteristics of the hierarchical management, roles and responsibilities of the managed and managing nodes in the hierarchy, and the related concept of management responsibility stack. Further, the paper discusses the characteristics of the messaging and configurability of the nodes in a hierarchical network, and introduces a problem called DTN management trilemma. The paper also presents a use case where the concepts of this paper are applied to network management of a hierarchical organization in a reference scenario, and the performance of the hierarchical management methods is compared to an equivalent nonhierarchical solution.

Mobile Ad hoc Networks (MANETs) is a collection of wireless mobile nodes, which form temporary networks over infrastructure-less environments. Over the last few years, Vehicular Ad hoc Network (VANET) technology has been considered as an active research area. VANET is a sub class of MANET with some unique characteristics such as fast vehicle speed, frequent topology changes and restricted mobility on roads. The communication between vehicles provides a new avenue for different types of applications such as safety, traffic management, entertainment, etc. These applications are categorized based on how data is transmitted from source to destination. The performance of such applications does not only depend on routing protocols, but also on the data dissemination mechanism. Data dissemination in VANETs is a significant factor, which can be accomplished using four different models: Dynamic Source Dynamic Destination (DSDD), Dynamic Source Static Destination (DSSD), Static Source Dynamic Destination (SSDD), and Static Source Static Destination (SSSD). Each one of these models is suitable for specific types of applications. In this paper, the authors study and evaluate the fault-tolerance of VANET under different data dissemination techniques in terms of throughput, average End-to-End delay, and percentage of packet loss. the authors used NCTUns 6.0 network simulator and IEEE 802.11p wireless communication standard. Their findings show that DSDV is more fault-tolerant than both DSR and AODV in terms of packet loss percentage for all dissemination techniques. However, AODV shows better performance in average End-to-End delay and throughput under DSDD and SSDD techniques.
