Reliable Link-Based Routing Protocol for Highly Dynamic Mobile Adhoc   Networks
  Traditional topology-based MANET routing protocols use stateful routing which increases the processing,communication and memory overheads. The high mobility of nodes in MANETs makes it difficult to maintain a deterministic route. To overcome this, stateless geographic routing protocols which ensure reliable data delivery have been proposed. It is found that link instability can be a major factor for unreliable data delivery. Driven by this issue, Link and Position based Opportunistic Routing (L-POR) protocol which chooses a forwarder based on the reception power of a node has been proposed. A back-up scheme is also proposed to handle communication holes. Simulation results show that the proposed protocol achieves excellent performance even under high node mobility.
