摘要：With the development of computer technology and widespread use rapidly, computer goes deeply into every areas of life and plays a very important role. AD HOC network technologies and standards, such as IEEE 802.11's ad hoc mode, allow the quick set up of a wireless network among a group of mobile stations, where the stations communicate with each other either directly or indirectly through multiple hops, without the aid of an inf rastructure (e.g., cables, access points or base stations). Since mobile stations are typically powered by batteries, the success of MANETs strongly relies on energy eff icient communications. The radio of a mobile station can be in one of three awake states, namely, transmitting, receiving, and idle listening, or in the doze state. To achieve this, at the same time, high precision time synchronization among computers appears more important than before. Especially in measurement, communication, f inance, electric, transportation, military affairs and other major areas, the precision of time synchronization have great effect on every system's safe directly
