We will propose an adaptive distributed power management (DISPOW) algorithm that adaptively preserves network connectivity and cooperatively reduces interference for the dynamic environment and the changing network topology thereby improving the network performance. The proposed algorithm distributively builds a unique stable network topology tailored to its surrounding node density and propagation environment over random topologies in a dynamic mobile wireless model. We will show that DISPOW, with adequate power levels, provides strongly connected reliable network, reduces interference and routing overhead consequently providing a shorter packet delay and improving network throughput by as much as 37%. We will also show how it stabilizes node connectivity over the dynamic network and environment and attempts to prevent node from being completely disconnected from the network. Comparing with common node power strategy, DISPOW significantly reduces average node power level in highly attenuating environment and alleviates the dependency of common node power strategy on few nodes that are isolated in the network because of their physical location and surrounding network environment.
