Per-hop Data Encryption Protocol for Transmitting Data Securely Over Public Networks

an efficient protocol for data aggregation in wireless sensor networks

sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...

Reversible Data Hiding For Embedding Data Securely in Encrypted Image by Reserving Room Before Encryption

Reversible data hiding with image encryption (RDH), since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. In previous work vacating room after encrypted image, which subject to some errors on data extraction and/or image restoration. In this paper, a novel method by res...

A New Fast Data Encryption Algorithm (FDE)

Effective data dissemination over multi-hop gigabit wireless networks

Optimal Transmission of Data Over Multi-Hop Networks

We study the end-to-end delay performance when transmitting data traac over multi-hop networks. Data is normally carried in transmission units (e.g., packet, frame, cell). The performance is strongly aaected by several factors, including header and payload sizes of the transmission units, and the eeect of pipelining these units over the multiple links. We determine the optimal payload size as a...
