摘要: | 最近,Barsi等人针对无线的异质传感器网路提出了一个节省能源的位置训练协定,传感器可经由此协定被训练并认知出它本身相对于附近之actor的粗略位置。在此协定中,传感器是利用actor所传输之讯息以及二元搜寻法,来认知出自己的粗略位置,因此Barsi等人称其协定为BINARY TRAINING PROTOCOL。在BINARY TRAINING PROTOCOL的运作中,actor交替广播control broadcast及data broadcast,因此,若传感器的清醒周期长度d为偶数,则在此清醒周期中,d/2个control broadcasts及d/2个data broadcasts被播放。我们因此猜测:如果在一个清醒周期中,actor所广播的d个broadcasts中仅有一个是control broadcast,其余(d − 1)个均是data broadcasts,则BINARY TRAINING PROTOCOL的效益能否提升?本论文之目的即在于验证此一猜测。 Recently, Barsi et al. proposed an energy-e?cient location-training protocol for heterogeneous actor-centric sensor networks where the sensors acquire coarse-grained location awareness with respect to the actor in their vicinity. This training protocol is called BINARY TRAINING PROTOCOL according to its nature that the sensors perform a binary Recently, Barsi et al. proposed an energy-efficient location-training protocol for heterogeneous actor-centric sensor networks where the sensors acquire coarse-grained location awareness with respect to the actor in their vicinity. This training protocol is called BINARY TRAINING PROTOCOL according to its nature that the sensors perform a binary search among the actor transmissions to locate their correct corona. In BINARY TRAINING PROTOCOL, the actor alternates control broadcasts (at full power level) with data broadcasts (at decreasing power levels), transmitting corona identities in decreasing order. Therefore in this training protocol, if the awake period of a sensor is an even number d, then during this awake period, d/2 control broadcasts and d/2 data broadcasts are broadcasted by the actor. We therefore conjecture: if during an awake period, the actor broadcasts only one control broadcast and all of the other (d-1) broadcasts are data broadcasts, will the performance of BINARY TRAINING PROTOCOL be improved? The purpose of this thesis is to confirm this conjecture. |
