[ns] Node Position

[Najma Ismat]

Hi,I am want to implement grid topology in mobile wsn and before the start of 
specific protocol operation i want to identify nodes in a grid so that routing 
protocol should only used nodes that exists in that grid. Nodes initial 
position and movement pattern is stored and taken from mobility pattern file. 
Can anyone guide how to achieve this also how should i run individual routing 
solution in every grid. I'll be extremely grateful if anyone can 
guide.Regards,Najma Ismat
