4-N intelligent MANET Routing Algorithm

Mobile Ad hoc Networks (MANET) use a communication technique that can transmit data between nodes without the support of fixed infrastructure. MANET is a multihop, self configuring and autonomous network that can use intermediate mobile nodes as a router and transmit data between mobile devices. A quadrant based intelligent energy controlled multicast algorithm for MANET identified during earlier research is the basis for the algorithm presented in this paper. Simulation results and comparison with other MANET routing algorithms highlighted that the algorithm is energy efficient and reliable but relatively slow for data transmission. An improved MANET routing algorithm is proposed in this paper which eliminates the data transmission delay limitation and increases the number of delivered packets. The new algorithm is called 4-N Intelligent Routing Algorithm as it selects a subset of 4 intermediate nodes located in the direction of the destination node and uses an intelligent energy matrix to distribute the load among the subset of nodes. Simulations were carried out of the proposed MANET algorithm using Opnet Modeler v16. Comparison with other MANET routing algorithms showed that the proposed algorithm successfully delivers more packets, reduces end to end delay and utilizes comparable energy for data transmission.
