NDN forwarding strategies are mainly developed receiver‐driven, where Interest forwarding and Data (content) delivery are controlled from the consumers' viewpoint. The receiver‐driven strategies are greedy by nature and emphasize optimizing the Interest forwarding, which is far from the performance bottleneck as an Interest is of tiny size in compared with a content's size. Thus, optimizing the content...
Routing messages in sparse and intermittently connected networks is one of the major challenging issues in Delay Tolerant Networking as an end-to-end path between the source and the destination is absent most of the time. To deal with this problem a wide range of routing protocols have emerged over time. One such protocol is MaxProp — which prioritizes both the schedule of packets to be transmitted...
Cloud computing becomes a buzzword now a day because of its simplicity, reliability, portability and security in maintaining and manipulating services from remote locations in the world. As the uses of cloud computing increase, more and more data centers are deploying throughout the world for providing high quality services to the consumers. The incremental performance of these data centers deserves...
A blind audio watermarking algorithm in Discrete Cosine Transform domain using the relationship among the consecutive groups of samples is proposed in this work. Here, we divided the DCT represented audio signal into equal-sized non-overlapping segments which in turn divided into four non-overlapping consecutive frames. Here, an informative relation between the frames in a segment is maintained to...
To reduce the passengers' adversity and elevate the social security, consumer rights, an effective and smart taxi control system is proposed in this paper. The system may help to reduce the different problems mass people face while travelling on a CNG driven taxi. Certitude of reasonable fare charging can be easily uphold by the proper implementation of this smart system. Forgery of driving license...
Optimizing the three most important network performance parameters i.e. Delivery probability, Overhead ratio, and Delay is challenging in Delay Tolerant Networks (DTN) due to high occurrences of network partitioning in these networks. Owing to the partitioning nature efficient routing or dissemination of messages is important in DTN. In this paper, we focused to improve the spray phase of Binary Spray...
A simple and effective audio watermarking algorithm based in time domain is proposed in this paper for controlling the unauthorized distribution of copyright audio. The algorithm makes use of the advantages of both embedding a watermark bit to an individual sample and embedding a bit to a group or frame of samples. Here, a frame of three positive valued samples is used to define the amount of distortion...
Routing schemes in Delay Tolerant Networks depend on the intermediate nodes to carry messages till the forwarding of the messages to other nodes or delivery of the messages to their destinations. Thus, efficient and faster spreading of messages is essential to reduce the delay of sending a message from source to destination. In this work, we aim to design a new agent aided routing scheme in Delay...
Delivering message in Delay Tolerant Networks is challenging due to its sparse nature and intermittent connectivity. Therefore efficient routing is very important for these networks. Here, we focus on the Spray and Wait routing schemes for Delay Tolerant Networks to avoid identical spraying technique and blind forwarding by mobile nodes. To avoid those problems, we first define an adaptive spraying...
Delivering messages in Delay Tolerant Networks is a nontrivial challenge due to its sparse nature and intermittent connectivity. Therefore efficient routing of messages is vital for these networks. In this work, we aim to adapt the spray phase of the Binary Spray and Wait routing scheme in Delay Tolerant Networks to avoid large communication overhead suffered by the scheme. We define an adaptive spraying...
Internet gateways are used to access the Internet services from the Mobile Ad Hoc Network (MANET). Internet gateways need to be discovered and selected in an appropriate way to deliver more packets to the Internet and reduce end-to-end delay. Existing gateway discovery schemes do not scale well with the number of nodes, traffic load, and speed of the nodes in MANET. To make it scalable, we proposed...
Integrating nodes in a MANET to the Internet require either a connection to the Internet or they can connect to the Internet through the Internet gateways or servers. For the second case a node in a MANET has to find out the gateway or server to connect to the fixed nodes in the Internet. End to end packet delay and throughput are strongly dependent on the time needed to discover the gateways. A source...
