Joint cost and secured node disjoint energy efficient multipath routing in mobile ad hoc network

The severe resource constraints and deployment environments of mobile ad hoc networks (MANETs) pose challenges for the security and energy consumption during data transmission for these networks. Multipath routing and energy consumption are the important factors to be considered in mobile ad hoc network as it provides a powerful tool for studying security aspects during data transmission. Advances in MANET technology have provided the availability of energy efficient reliable and multi path routing for intrusion tolerance with capability of identifying reliable routes, determining the best redundancy level to increase the operational lifetime of the network. Identifying a secured and energy efficient multipath routing for MANET represents the basic challenge during data transmission. In order to overcome such limitation, a hybrid method called as joint cost and secured node disjoint energy-efficient multipath routing (NDE-MR) is designed for MANET to reduce the energy consumption and execution time during the multipath routing and to improve security during data transfer. Node initialization initializes the mobile nodes with energy efficient model by obtaining the neighbor node data. Next, cost-based multipath route discovery model identifies the path with the least transmission cost through which data forwarding is made. Finally, security is achieved through node disjoint path model by splitting the data packets into different segments. Simulation results show that the NDE-MR model is able to reduce energy consumption and execution time during multipath routing and to increases the security of the network.
