... A Mobile Adhoc Network (MANET) is one that nodes come collectively as needed, not essentially with any sustain from the active Internet infrastructure or any other kind of permanent stations. We can say that an ad hoc network is an autonomous system of mobile hosts connected by wireless links. The c ...
