Abstract

Compared with traditional wireless networks, the congestion control design of Wireless Sensor Networks (WSN) is more significant to the network performance due to its own characteristics. In this paper, we design a mechanism using spare resources to mitigate congestion in a many to one network. We classify the node congestion into two categories according to the reasons and propose two distributed algorithms which can find an alternative path using the neighbor table efficiently. At the end of this paper, we simulate the drop rate of WSN to evaluate our mechanism. The simulation shows that using our mechanism improves network transmission quality significantly.

Keywords: wireless sensor network congestion control
