- Propose an individual beacon order adaptation (IBOA) which can individually adapt the beacon interval and duty cycle of each node at the same time to the node’s individual performance requirements
- IEEE 802.15.4 is one of the most important protocols for wireless sensor networks.
- In an IEEE 802.15.4, low power consumption or long lifetime can be achieved by low duty cycles. However, low duty cycle can bring large end-to-end delay, since any unfinished or newly added operation in the current active portion has to wait until the next active portion to perform.
- To improve the performance of that protocol in consideration of the trade-off between power consumption and end-to-end delay, duty cycle adaptation algorithms are effective solutions.
- In this paper, the authors propose an individual beacon order adaptation (IBOA) algorithm which can individually adapt the beacon interval and duty cycle of each node at the same time to the node’s individual performance requirements.
General Description of IBOA :
- In this algorithm, the authors set SO to a constant and set BO to the adaptation performed by IBOA algorithm.
- The IBOA adapts BO of each node individually. The IBOA assigns a BO for each nodes in the network. Thus the beacon interval and duty cycle of each node may not be as same as that of another node at one time and can be adapted to the node’s individual performance.
- The benefit of individually adapted beacon intervals is that the active portions of any two different nodes, which are used to compete for channel access, may not begin at the same time.
