Many applications, especially those that require visualizing complex information, rely on manipulating and presenting data as graphs composed of nodes and links. A graph, in the mathematical context, is a set of objects represented as vertices, or nodes, and a set of links connecting some pairs of objects. The graph… Read more »
This is another example of using Processing to create animations. The GraphAnimation program demonstrates packet forwarding by flooding. A packet sent by node A is replicated by every node (router) it reaches and sent in all connected links until it reaches the destination node N. Knowing the shortest route, node… Read more »
An ad hoc node refers to a device in a wireless ad hoc network. Ad hoc networks (or more accurately, mobile, multi-hop, wireless networks) are a class of networks that does not depend on any central administration or infrastructure in its operations. Unlike wired networks, an ad hoc network could… Read more »
