Reliable multicast in wireless networks has been well studied in the sense to solve the feedback implosion issue, which, however, can not reduce the number of retransmissions in order to recover all lost packets at receivers. Most recently, it has been proposed to use network coding for reliable multicast in wireless LANs to reduce the number of retransmissions. In this paper, we propose two new models...
The paper introduces a secure DSR protocol, which is based on the principle of the sequence number increment and the scheme of the end-to-end acknowledgement. The OPNET simulation result shows that the secure routing design can resist the black-hole attack effectively.
TMO Global Logistics currently provides cargo tracking services that rely on clients calling the TMO office to request estimated time of arrivals (ETAs) and TMO employees calling shipping dispatchers to find current cargo locations and relaying experience-based ETAs to the client. For TMO, minimizing the resources (dollars, man-hours, data storage space, and bandwidth) spent accepting ETA requests,...
Multidimensional data indexing has received much research attention recently in a centralized system. However, it remains a nascent area of research in providing an integrated structure for multiple queries on multidimensional data in a distributed environment. In this paper, we propose a new data structure, called BR-tree (Bloom-filter-based R-tree), and implement such a prototype in the context...
The construction of multicast light-trees in WDM network with sparse splitting has been proved to be an NP-complete problem. To reduce the diameter of the tree and average delay, an improved algorithm called Nearest Connector First Heuristic (NCFH) is proposed. The simulation results show that the proposed algorithm performs well.
Since forward reservation protocol (FRP) and backward reservation protocol (BRP) both have apparent drawbacks when they are used in multi-domain optical network. So we propose a reservation protocol based on priority in multi-domain optical network with wavelength conversion, which achieves the trade-off between blocking probability and connection setup time.
