摘　　要：One main issue of degrading IEEE 802.15.4performance is the beacon conflict which increases the energy consumption.However,IEEE 802.15.4does not address a solution to avoid the beacon conflict.In order to reduce this beacon conflict,an individual time division(ITD)algorithm based on IEEE 802.15.4is proposed.In this algorithm,a coordinator assigns the time division(TD)for each associated coordinator so that different coordinators transmit a beacon frame at different time slice.In this way,the beacon conflict is decreased substantially.The experimental results show that ITD reduces both the beacon conflict and the network energy consumption,and improves the network performance.One main issue of degrading IEEE 802.15.4performance is the beacon conflict which increases the energy consumption.However,IEEE 802.15.4does not address a solution to avoid the beacon conflict.In order to reduce this beacon conflict,an individual time division（ITD）algorithm based on IEEE 802.15.4is proposed.In this algorithm,a coordinator assigns the time division（TD）for each associated coordinator so that different coordinators transmit a beacon frame at different time slice.In this way,the beacon conflict is decreased substantially.The experimental results show that ITD reduces both the beacon conflict and the network energy consumption,and improves the network performance.
