IEEE 802.15.4 (15.4) is a standard which specifies the physical and medium access control for Low-Rate, low-cost, low-power Wireless Personal Area Networks (LR-WPANs). Nowadays, due to its advantages of low power and low cost, IEEE 802.15.4 is widely used in a large number of applications such as health care monitoring, wireless sensor networks, and several industrial automation fields. With the recent increase in the importance of the beacon collision problem, several possible solutions have been proposed. These can be divided into two categories: proactive and reactive methods. However, due to their inherent limitations, neither type has provided substantial solutions to the beacon collision problem.
