Since the existing power control algorithms for ad hoc nodes are simple and consume too much energy,this paper proposes a step power control of ad hoc nodes(SPCA).This algorithm divided the radiative power at each node into several regions,and Ad hoc nodes applied a stepping probe strategy to choose the appropriate power region according to conditions such as network connectivity,the state of the communicating environment,and so on,which could improve the power efficiency,lengthening the battery life of the nodes and enhancing their adaptability to complex environments.Theoretical analysis and simulation of the proposed algorithm were given.The results indicated that SPCA serves the needs of complex ad hoc environments well,decreasing the number of alterations to connecting states and increasing the Ad hoc lifetime.
