Abstract

Energy-Saving techniques for mobile communication systems has recently received a great deal of attention in Fifth Generation (5G) networks. The Device-to-Device (D2D) communication in 5G networks has increased number of users and the data transmission rate among the mobile nodes in Cloud Assisted-Mobile Ad Hoc Networks (CA-MANETs). However, the connection between these mobile nodes and peer nodes has to frequently renew due to mobility, link failure, routing overhead and low battery power. During this period, it consumes high energy in searching and linking the mobile nodes. Hence, this research work attempts to reduce the energy consumption by proposing an Energy-Efficient Cloud-Assisted Routing Mechanism (EECRM) for CA-MANETs. Energy consumption is minimized by performing fast local route recovery among mobile nodes and peer nodes. If the link failure occurs, the backup nodes are identified by neighbour nodes and these backup nodes form an overlay that provides the coverage and this overlay network consumes less energy in routing. The results obtained from this proposed routing algorithm provides better performance in terms of less energy consumption, residual energy and network lifetime when compared with other existing network models and routing protocols.
