Speed Up-Greedy Perimeter Stateless Routing Protocol for Wireless Sensor Networks (SU-GPSR)

This paper proposes a position-based routing scheme called Speed Up-Greedy Perimeter Stateless Routing Protocol for Wireless Sensor Networks (SU-GPSR). The speed up mode works together with greedy mode to provide a solution for data transmission in WSN. Unlike other variants of greedy perimeter stateless routing protocols, SU-GPSR not only embraces both still nodes and mobile nodes in one unified scheme, but provide a complete energy consumption consideration when evaluating the potential next hop. The simulation results reveal that the SU-GPSR outperforms EGPSR and FA-GPSR from various aspects in both dense and loose network size.
