Internet Connectivity for Mobile Ad Hoc Networks Using Hybrid Adaptive Mobile Agent Protocol
Internet-based Mobile Ad Hoc Networking (MANET) is an emerging technology that supports self-organizing
mobile networking infrastructures. This is expected to be of great use in commercial applications for the next generation
internet users. A number of technical challenges ar e faced today due to the heterogeneous, dynamic nat ure of this hybrid
MANET. A new hybrid routing scheme AODV ALMA is pro posed, which act simultaneously combining mobile agents to find
path to the gateway and on-demand distance vector a pproach to find path in local MANET is one of the unique solution. An
adaptive gateway discovery mechanism based on mobil e agents making use of pheromone value, pheromone decay time and
balance index is used to estimate the path and next hop to the gateway. The mobile nodes automatically configure the address
using mobile agents first selecting the gateway and then using the gateway prefix address. The mobile agents are also used to
track changes in topology enabling high network con nectivity with reduced delay in packet transmission to Internet. The
performance tradeoffs and limitations with existing solutions for various mobility conditions are evaluated using simulation.
