Abstract:

Based on the characteristics of sensor networks, this paper proposes a new algorithm for angle-area-based flood routing（AAFR）. The basic idea is that the packets generated by flooding are limited in a constructed angle area. Compared with traditional flooding, AAFR can reduce the routing overhead. I n addition, it is also simpler and more effective than the hierarchical algorithm. Theoretical analysis and simulation results show that the new algorithm has better performance.
