Routing protocols for wireless ad hoc ATM networks

Abstract

One of the major problems in multihop ad hoc ATM networks is the establishment and maintenance of virtual connections. Therefore, PNNI, IP and ZRP are investigated as possible routing protocol candidates. All three are modelled and analysed in terms of signalling overhead. The analytical model shows that ZRP is the most promising candidate as it is able to be adapted to any kind of network topology. As ZRP has been developed for IP it has been changed for ATM routing. Computer simulations show that the analytical model is accurate and the delays due to topology changes are very limited.
