hi everybody,

i would be very pleased if someone gives me any informations about theses problems in ad hoc networks:

1- why and when do we use clustering? what are the services that the clusterhead is supposed to give?

2- can we consider the clusterheads as partial central authorities? if yes how can clusterheads authenticate each others?

3- can we simulate clustering using a network simulator like ns? can we apply clustering in a realistic environment? 

any help will be appreciated.

regards
