ABSTRACT
The advancement of science and technology had made mobile ad hoc network an important tool to access network
of next generation. Recently, numerous multipath routing protocols for mobile ad hoc network are reported in
literature. Each routing methods works based on their salient feature, but failed to control congestion, energy
efficiency, overhead packets, signal stability during data transmission which leads to edge effect, signal decay and
bottleneck situation of the bandwidth consumption. In this paper a novel approach havely Geographical Distance
based Ad Hoc On-demand Distance Vector Routing (GD-AOMDV), which selects the path based on transmission
distance value to limit and control the congestion and control overheads has been proposed. The salient feature of
the proposed model is that it establishes a relationship between path distance and MANET design parameters
including transmission range, consumption of energy and bandwidth. The accuracy of the proposed scheme is
analyzed and validated with the experimental results in respect to various flow using NS2 simulations.
