For mobile ad hoc networks (MANET) optimization of energy consumption has greater impact as it corresponds directly to lifetime of a network. Geographic adaptive fidelity (GAF) protocol extends the lifetime of self configuring system while preserving connectivity. By identifying the redundant nodes GAF switch off their radios to conserve the energy. Due to limited radio range, node connectivity is limited to adjacent vertical and horizontal grids only and neighbors in diagonal are out of reach. This issue is known as unreachable corner of GAF square grid architecture. This paper proposes hexagonal grid architecture for GAF named as GAF-HEX which replaces virtual square grid into hexagon grid. This paper introduces two node mapping algorithms GAF-C and GAF-E for GAF-HEX. GAF-C maps nodes with reference node at centre and GAFE maps with reference node at the end of hexagonal grid. These architectures are evaluated on different performance metrics like packet delivery ratio, throughput and energy consumption. Our simulation results shows that GAF-HEX improves packet delivery ratio and throughput by keeping energy consumption almost same as GAF. These protocols are tested for different mobility and traffic rate.
