无线传感器是目前最受关注的研究领域之一,它涉及到航空机载测试技术、通信网络技术、信息处理技术以及微电子技术等研究方向。但是无线传感器的体积通常很小,导致携带的电量也非常有限,而替换传感器的电池或者给电池充电是很不现实的。因此,如何降低无线传感器的发射功率成为目前科学领域的研究重点。本文针对无线传感器的功率控制问题,提出了将博弈论与功率控制相结合,目的在于保证每个传输节点的最低Qo S的前提下,尽可能的降低无线传感器的发射功率,提高传感器的使用寿命。
Wireless sensor is one of the most concerned research fields at present. It involves the research direction of airborne test technology, communication network technology, information processing technology and microelectronics technology. However, the size of the wireless sensor is usually small, resulting in a very limited amount of power to carry, and replacing the sensor battery or charging the battery is not realistic. Therefore, how to reduce the transmit power of wireless sensors has become the focus of scientific research. In order to solve the problem of power control in wireless sensor, this paper proposes combining game theory with power control. The purpose is to ensure the lowest QoS of each node and reduce the transmitting power of wireless sensor as much as possible and to improve the service life of the sensor .
