Link reliable on-demand distance vector routing for mobile ad hoc networks

An established infrastructure or centralised control system is not necessary for communication between nodes, or mobile devices, in a mobile ad hoc network, or MANET. To adhere to the quality of service (QoS) standards, Unipath routing protocols find a single dedicated route between a pair of solicited source and destination within the network. In this study, a modified version of the popular ad hoc on-demand distance vector (AODV) called the link reliable on-demand distance vector (LRODV) is proposed. The AODV uses the traditional routing measure hop count to determine the shortest path between a source and destination pair, but this does not ensure link dependability. The LRODV uses an enhanced cumulative expected transmission count (enh-CETX) to select a link trustworthy route between a source and destination pair, preventing link failures and route breaks in highly dynamic ad hoc networks. In terms of quality of service (QoS) metrics, the performance of the LRODV protocol using NS 2.35 with different network flows under the random way-point mobility model is compared with that of the AODV routing protocol. The LRODV reduces 4.822741% of routing overhead, 2.938256% of packet loss ratio, 7.429350% of normalised routing overhead, and 0.609278% of energy usage as network traffic increase. In comparison to the AODV routing protocol, it boosts the throughput by 2.741449% and also packet delivery ratio by 2.938256%.
