Look A-Head Probabilistic energy-aware Routing Strategy For Delay Tolerant Network

چکیده
DTN probabilistic routing protocols forwards message to a node that holds high predictability value to meet its destination. However, the message replication continues on the high probable peers while high probable peers continue to receive the transmissions from multiple sources. Such rampant transmissions drain out the battery and node can go to the dead state thus will not be able receive its destined messages. In this paper, we have proposed a Look-ahead probabilistic energy aware routing strategy for delay tolerant network. In proposed method, the message forwarding decision jointly observes the probability value and remaining energy of the current connected node. We have compared the performance of LaHEA with energy aware routing strategy. The proposed method has reduced the number of transmission, message drop and increase the delivery ratio.

Energy-Aware Probabilistic Epidemic Forwarding Method in Heterogeneous Delay Tolerant Networks
Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...
متن کاملCongestion estimation of router input ports in Network-on-Chip for efficient virtual allocation
Effective and congestion-aware routing is vital to the performance of network-on-chip. The efficient routing algorithm undoubtedly relies on the considered selection strategy. If the routing function returns a number of more than one permissible output ports, a selection function is exploited to choose the best output port to reduce packets latency. In this paper, we introduce a new selection s...

Abstract Vehicular Ad Hoc Network (VANET) is a particular type of mobile ad hoc network in which vehicles communicate between themselves using wireless antenna. Due to unique characteristics of VANETs (e.g. high mobility of nodes and dynamic topology), routing is one of the challenging tasks in such networks. Consequently, delay tolerant networks which consider the disconnect nature of...
