| 英文摘要: |
| The current geographic routing protocols arise data congestion if a multi-flow bypasses a hole simultaneously and excessive energy consumption of hole boundary nodes because these protocols tend to route data packets along the boundaries of void areas (holes) by perimeter routing scheme. This scheme possibly enlarges the holes phenomenon (called hole diffusion problem) and shortens the life span of the network. A novel geographical routing algorithm based on a potential field approach (PFA) is proposed to deal with multiple holes scenario and restrict data to forward near boundary of a hole. That is, data packets are attracted to its sink and are repulsed away from the hole(s). Simulation results show that PFA is superior to other protocols in terms of packet delivery ratio, network lifetime. |
