碩士 === 義守大學 === 電機工程學系 === 100 === The wireless sensor network is posed by the sensor nodes, because sensor nodes are battery to provide electricity sources, and reduce sensor node duty cycle, however, the superframe can not be adaptive adjustment structure in IEEE 802.15.4 standard, when the network load increased, under the limited duty cycle, easy to cause the collision of data between devices, resulting in additional energy consumption and network performance of the decrease low order in accordance with network network's status condition dynamics of the to tune superframe the work cycle, this paper, is through the main ECAP (Extend Contention Access Period) and its improvement of active extend contention access period (AECAP) algorithm to modify the bottom part to save battery power.
