A Rate-Allocation Based Multi-path Congestion Control Scheme for Event-Driven Wireless Sensor Networks

In this paper, we proposed a rate-allocation based congestion control approach, called multi-path-congestion control method (MUCON for short), which enforcing high path availability of packet delivery for event-driven Wireless Sensor Networks (WSNs) consists of two parts. The first is constructing a spanning tree to connect all sensor nodes of a WSN to the sink for initial routing. The second is establishing a fair packet forwarding environment by employing multi-path and rate control to deliver packets through routing paths with a balanced manner. Experimental results show that this method can effectively improve a WSN's throughputs, shorten end-to-end delays and reduce packet loss rates.
