Multicast is an important collective communication operation on multicomputer systems, in which the same message is delivered from a source node to an arbitrary number of destination nodes. The star graph interconnection network has been recognized as an attractive alternative to the popular hypercube network. In this paper, we first address a dual-hamiltonian-path-based (DHPB) routing model wi...

Path planning is an important part of the unmanned aerial vehicle (UAV) to realize its autonomous capabilities. Aiming at shortcomings traditional ant colony algorithm-based trajectory method, which has slow convergence speed and easy fall into local optimum, a path method based on improved algorithm proposed. First, dynamic adjusting factor added heuristic function improve directivity selectio...

1 Supported in part by a grant from the Texas Advanced Research Program. Abstract-We consider the problem of finding an optimum path from each node in the network to a destination node in the network. Typically, each edge in the network is assigned a weight value (e.g. bandwidth or delay), and a metric function (e.g. min or +) is applied consecutively to the edges in the path. The result is the...

In the last years, tablets and smartphones have been widely used with the very same purpose as desktop computers: web browsing, social networking, banking and others, just to name a few. However, we are often facing the problem of keeping our information protected and trustworthy. As a result of their popularity and functionality, mobile devices are a growing target for malicious activities. In...
