A Hierarchical Routing Protocol for Ad Hoc Network

A hierarchical structure has been introduced to wired network.But,In Ad hoc network, it is difficult to introduce the hierarchical structure because all mobile hosts are always moving in the network. A new hierarchical routing protocol called Hi-TORA based on the autonomous clustering scheme is proposed to solve this problem.Hi-TORA includes cluster scheme and routing protocol among nodes.It applies TORA's thought,but they are different in some point.In the end,this article compares Hi-TORA with DSDV, DSR, ARP and TORA.
