Angular Routing Protocol for Mobile Ad Hoc Networks

We present angular routing protocol (ARP) for mobile ad-hoc networks. ARP is a new position-based routing protocol that uses an improved geographic forwarding route packets as and when possible. If the geographic forwarding fails, it uses an angle-based forwarding scheme to circumvent voids in sparser networks. ARP does not require a routing table nor does it require nodes to establish/maintain routes. Each node maintains a one-hop neighbor table using an adaptive beaconing protocol. Nodes forward packets to the destination solely based on the neighbor table. To evaluate the performance of our protocol we simulated ARP in GloMoSim. Our simulation study shows that our protocol achieves high packet delivery rate while incurring low overhead compared to greedy perimeter stateless routing (GPSR)
