Abstract
In this paper, an effective congestion control al- gorithm is proposed to increase the end-to-end delivery success ratio of upstream tra±c by reduction of bu?er drop probabili- ties and their deviation in wireless sensor networks. According to the queue length of parent and child nodes, each child node chooses one of the parents as the next hop to the sink and controls the delay before transmission begins. It balances tra±cs among parents and mitigates congestion based on congestion level of a node. Simulation results show that the proposed algorithm re- duces bu?er drop probabilities and their deviation and increases the end-to-end delivery success ratio in wireless sensor networks.
