back20 (back20) 于 (Tue Apr 1 10:33:43 2008) 提到:
Given n nodes in the field(assuming in a large rectangle area) randomly
deployed, and all of them are doing random movement( you can assume speed v,
if needed, and nodes cannot move out of the large rectangle). What is the
probability that there are 0 node, 1 node, 2 nodes,..., n nodes in a small
rectangle(the small rectangle is inside the large rectangle)?
Anyone have ideas for the solution?
