N2 - Most existing routing algorithms assume wireless nodes use maximal transmission power or set up the power at the beginning of the network configuration. These static approaches potentially introduce signal interference that can be mitigated through power control. In this paper, we propose a Joint Channel assignment, stable Routing and adaptive Power control (JCRP) approach that dynamically controls the transmission power to avoid the channel interference for improving the channel utility. Our JCRP allows a node to control its transmission power to a certain value at which it has a longest channel conflict-free time. Besides, we propose a novel routing metric integrated selecting stability (ISS) to measure the quality of links, which considers node mobility and channel interference, together with the dynamical power control. The simulation results demonstrate that our JCRP significantly outperforms the related routing algorithms in terms of network throughput.
