Abstract: Mobile ad hoc network is without infrastructure and without base station wireless network and decentralized way for a large network thier number of nodes dynamically, therefor, the connection established between source node to destination node is very difficult. The challenge is interconnecting ad hoc network to the internet seems from the needs to inform ad hoc nodes about available gateways in an extremely challenging scenario while a making a minimum consumption of the source network resources. Then an efficient gateway discovery of an ad hoc network becomes one of the central factors to enable the economic consumption of hybrid ad hoc network in future mobile and wireless network. In mobile ad hoc network have multihop, therefore, several reachable gateways for mobile node at any period of time. If the mobile node receives gatways advertisement from more than one gateway. It has to determine which gateway to use for connecting to the network. Most existing protocol choose the gateway which is closer in terms of the number of physical hops. This study has focused on design an efficient and adaptive subnetting hybrid gateway discovery mechanism on the basis of dynamic TTL value adjustment such that congestion and unnecessary overhead is reduced. Selecting the gateway on the basis of one and two parameters will increase the performance and throughput of the network. The main objective of adaptive gateway discovery to determine the optimal TTL value in terms of number of hops to determine the proactive area, nodes outside this area follow the reactive approach. Consequently, for achieving a good trade off between performanceand network operating expense.
