A Survey on Opportunistic Routing Protocols
نویسنده
چکیده
Opportunistic routing (OR) is a recent routing technique for wireless multihop networks. It exploits the broadcast nature of wireless medium which is not utilized by traditional routing. The important features of OR is selection of forwarding nodes and co-ordination among the nodes to deliver the packets to their destination. Therefore, OR works well in wireless multihop networks with higher node density such as mesh or sensor networks. OR enables multiple paths and dynamic relay selection, thus it obtains higher link reliability and larger transmission range. This paper reviews some of the OR protocols.

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...

Mobility intertwines with routing protocols play a vital role in opportunistic networks. First and foremost, mobility creates opportunities for mobile nodes to connect and communicate when they encounter. A series of encounter opportunities can spread a message among many nodes and to a large area until eventual delivery. Further, mobility properties, when utilized by routing protocols, can gre...
متن کاملOpportunistic Routing Protocols for Wireless Sensor Networks: A Survey
One of the most discussed topics in Wireless Sensor Network (WSN) is the routing protocol used in the networks. These protocols largely affect the performance and the lifetime of the network as transmission of data uses a significant proportion of the total energy in WSNs. The sensors in WSNs run using batteries thereby making energy consumption an important design constraint for them. Over the...
متن کاملPerformance Comparison of Routing Protocols in Opportunistic Networks
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 paper, we provide a survey of the main routing approaches in OppNets and cla...
