Routing in Opportunistic Networks

چکیده
In Opportunistic Networks (OppNets), mobile devices transmit messages by exploiting the direct contacts, without the need of an end-to-end infrastructure. Disconnections of nodes and high churn rates are normal features of opportunistic networks. Hence, routing is one of the main challenges in this environment. In this article, we provide a survey of the main routing approaches in OppNets and classify them into three classes: context-oblivious, mobility-based, and social context-aware routing. We emphasize the role of context information in forwarding data in OppNets, and evaluate the relative performance of the three routing techniques. Finally, we present how context-based information is used to route data in a specific subclass of OppNets: Sensor Actor Networks (SANETs).

Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...
متن کاملMax-Pivot Routing for Opportunistic Networks
Opportunistic networks are challenging types of networks where network connections are imminent. Network topologies are dynamic and can rapidly change. A path between a source node and a destination node may or may not exist, the network can be disconnected. This type of behavior observed under opportunistic networks makes classical networking solutions impractical. Thus, traditional routing al...
متن کاملOptimum node placement in wireless opportunistic routing networks
In recent years there has been a growing interest in Opportunistic Routing as a way to increase the capacity of wireless networks by exploiting its broadcast nature. In contrast to traditional uni-path routing, in opportunistic routing the nodes overhearing neighbor’s transmissions can become candidates to forward the packets towards the destination. In this paper we address the question: What ...
متن کاملEncounter based Routing in Opportunistic Networks
Opportunistic networks are wireless networks which may be used in areas where large delays are presented between data transmission also long distances may be handled by nodes. In these networks nodes may communicate with others through intermediate nodes. Data transmission takes place via various routing protocols. An opportunistic network provides standard routing protocols that are epidemic r...
متن کاملSurvey on Opportunistic Routing in Multihop Wireless Networks
Opportunistic routing is based on the use of broadcast transmissions to expand the potential forwarders that can assist in the retransmission of the data packets. The receptors need to be coordinated in order to avoid duplicated transmissions. This is usually achieved by ordering the forwarding nodes according to some criteria. The proposed opportunistic routing protocols differ in the criterio...

Opportunistic networks are a kind of Ad Hoc networks that make use of meeting opportunities from mobile nodes to realize the network communication which doesn't need a full path between the source nodes and destination nodes. It’s tolerant in latency and network division. It’s a great challenge to design routing protocols in opportunistic networks in that the movements of nodes are uncertain le...
