Abstract

Wireless health monitoring networks (WHMNs) usually characterized by limited bandwidth resource and large amount of data, so to improve the network throughput of the wireless health monitoring network is a key challenge. Besides, as the data transmitted in the WHMNs are about the health or even the life of the people being monitored, so the real-time ability of the network should be ensured. In this paper, an adaptive transmission power based congestion control (Acc) mechanism was designed to achieve high throughput and real-time for a three-tier semi-self-organizing health monitoring network. The router nodes adjust their wireless transmission power according to the current network topology state and the communication state of the network adaptively to balance network load and reduce network congestion. The congestion control methods proposed in this paper have the characteristics of low power consumption and low communication overhead. Experiments have shown that the WHMN with the proposed Acc mechanism performs better than the WHMNs without the Acc in end-to-end delay and network throughput.
