A Knapsack-based buffer management strategy for delay-tolerant networks
In delay-tolerant networks, the dramatic change of topology and the frequent interruption of connections make it difficult to forward the message to destination. Routing protocols in DTNs seek to improve the delivery ratio through increasing the number of message copies. However, the redundant message copies easily cause the occurrence of buffer’s overflowing. In this paper, in order to maximiz...
متن کاملA Knapsack-Based Message Scheduling and Drop Strategy for Delay-Tolerant Networks
Because of the dramatic changes in topology and frequently interrupted connections between nodes, messages in delay-tolerant networks are forwarded in the store-carry-forward approach. Routing methods in such an environment tend to increase the number of messages to improve the delivery ratio. However, excessive message copies lead to buffer overflows because of limited storage space. Therefore...
متن کاملBuffer Management for Preferential Delivery in Opportunistic Delay Tolerant Networks
Delay Tolerant Networks (DTN) present many challenges that are not present in traditional networks. Many stem from the need to deal with disconnections which directly impacts routing and forwarding. However as these networks enable communication between wide range of devices, there are secondary problems that routing strategies may need to take care of such as to deal with limited resources lik...
متن کاملIntegrating Buffer Management with Epidemic Routing in Delay Tolerant Networks
Problem statement: The Design of Delay Tolerant Network (DTN) routing protocols has focused to operate in an environment where there is no guarantee of end to end path between source and destination at all points of time. The DTN research has focussed primarily on applications that are delay tolerant. But it can also be used to provide real time information like accident alert in VANETs and eme...
متن کاملLMOP Based Hybrid Routing Strategy for Delay/Disruption Tolerant Networks
In this paper, routing problem of Delay Tolerant Networks (DTN) was investigated and a new routing scheme was proposed based on the Epidemic routing. By combining the advantage of a variety of related routing algorithm, a Limited Multi-copy Optimal Path-Hybrid Routing (LMOP-HR) was put forward belonging to the flooding message copies strategy. An optimal tree mixed strategy based on priority wa...
