Delay Tolerant Networks (DTN) are sparse ad hoc networks in which no contemporaneous path exists between any two nodes in the network most of the time. Due to non-availability of end-to-end paths, multicast protocols of traditional networks fail in DTN because they try to find connected multicast graph between source and destination nodes before forwarding data packets. Routing protocols proposed...
This paper aims to introduce the hard optimization problem of determining tree-based explicit multicast routes with minimum cost. Explicit multicast routing has been proposed as a technique to solve the problem of multicast scalability in IP-based networks. Tree-based explicit routing is a special routing technique in which the multicast tree is encoded explicitly in the datagram headers. These enlarged...
Delay-tolerant networks (DTNs) have the capacity to interconnect the devices in roomy regions unlike todaypsilas networks. In this paper, we propose a routing scheme named time interval routing (TIR) to increase deliver ratio and decrease deliver latency in DTNs. TIR, only using limited and local information as well as simple algorithm, chooses the node in transmission range with the least time interval...
Based on the study of IEEE-1355 communication bus protocol in rugged environment, this paper puts forward a scheme of wormhole routing in network layer. Also a prototype of this wormhole router based on FPGA in rugged environment is designed and implemented. Experiment result shows that this solution can meet the demand of IEEE-1355 communication bus.
Opportunistic routing (OR) schemes, such as ExOR, have been shown to provide significant throughput gains over traditional best-path routing schemes for wireless networks. Though the performance of OR schemes depend on the bit-rate, they currently use a fixed rate for transmitting packets. While several schemes have been proposed for selecting bit-rate for unicast transmission to a single receiver,...
Network coding is known to improve throughput by mixing information from different flows and conveying more information in each transmission. Recently some proposals have demonstrated the benefits of applying network coding to wireless networks with broadcast transmissions. It is expected that the opportunities for coding and the corresponding gains depend on the bit-rate chosen for determining routes...
