摘要：Nodes in ad hoc networks form dynamic topologies typically with scarce resources, such as energy and bandwidth. A main challenge in the operation of such networks is the efficient allocation of resources for radio communications. In this context, the presented paper proposes a power control mechanism created as a network-assisted function of ad hoc cognitive packet-based routing and aimed at reducing both energy consumption in nodes and mutual interference of adjacent communications. Simulation results in NS-2 show significant energy savings after applying the proposed algorithm. In addition, simulation results and a mathematical analysis of interference models, depict a reduction of neighboring radio interference and results in a promising increase of network throughput.
