In MANET, nodes are able to communicate with each other for a short range only. To extend the communication range of MANET, an Internet gateway is used which acts as a bridge between the conventional network and MANET. To enable the long range communication, a MANET node needs to discover and then select the appropriate gateway using various proposed schemes. Some of the schemes suffer from lack of efficient gateway discovery mechanism. They use a single Hop count metric to select gateway which can be a bottleneck in the network. This paper aims at providing a simple and an efficient adaptive gateway discovery and selection mechanism using fuzzy logic to combine two metrics Hop Count and Latency which leads to selection of a less congested as well as short path.
