Adaptative power-aware metric for mobile ad-hoc networks

Energy efficiency routing is required to well use limited power resources in wireless ad hoc networks,. In this paper, we investigate problems of minimizing transmission power routing, which depends on distance between nodes, and cost aware routing, which depends on remaining battery power of nodes, as reference algorithm. As the result of our research we propose a new linear algorithm, called power-cost-aware algorithm, that uses both power consumption and cost metric depending on the battery's residual capacity, to maximize the lifetime of both network and node. Our simulation results indicate that the proposed power-cost-aware metric performs as good as minimization transmission power and cost aware metrics in sparse networks and outperforms those metrics as the network becomes more dense.
