The Content Centric Networks (CCN) replaces the IP narrow waist of the Internet architecture by a content layer. When a node wants to access a piece of content, it sends an Interest packet to the network. The network then, using the name of the content for routing, forwards the Interest to one or more copies of the content object. In this paper, we present the implementation of a OpenWRT OS based...

Mission planning plays an important role in satellite control systems, especially with increase of number of satellites and more complex missions to be planned. In a general setting, the satellite mission scheduling consists in allocating tasks such as observation, communication, etc. to resources (spacecrafts (SCs), satellites, ground stations). For instance, in ground station scheduling the aim...

Finding an optimal solution is computationally hard for most combinatorial optimization problems. Therefore the use of heuristics methods aims at finding, if not optimal, near optimal solutions in reasonable amount of computation time. Due to lack of knowledge about the landscape of fitness function, searching the solution space by heuristic methods becomes very challenging. One can search the solution...
