【摘要】 E-mail:wenkaikai@21cn.com摘要在移动Adhoc网络(MANET)中,节点兼备主机和路由器的功能,各个节点协同工作维持网络的连接性。由于能量的限制,网络面临生存周期、无线资源利用率以及时延等几方面的挑战,这使得Adhoc网络中的功率控制成为当前的研究热点。文章分析了功率控制对网络性能的影响以及目前功率控制的主要方法,并在文章的最后指出功率控制研究的发展方向。更多还原

【Abstract】 In the mobile Ad hoc networks(MANETs),node cooperate each other to maintain network connectivity and perform the function of host and router.Due to energy-limited,MANETs faces to the challenge of lifetime,wireless resource utilized efficiency and delay.At present,power control is a focus of research in the MANETs.In this paper,we will provide a detailed description of issues and survey the power control approaches that have been proposed in the literature,and the direction of power control is proposed.更多还原
