The 2.4 GHz industrial, science and medical (ISM) band is a license free band allocated for a variety of consumer applications: environmental monitoring, agriculture, medical care, smart buildings, factory monitoring and automation, and numerous military applications. This project focuses on the adaptive interference avoidance scheme for IEEE 802.15.4 to allow coexistence with IEEE 802.11b/g in the 2.4GHz ISM band. A wireless sensor network (WSN) consists of small nodes with sensing, computation, and wireless communication capabilities. It is an exciting new technology and can also be considered as the underlying infrastructure that will be integral part of future ubiquitous and embedded computing applications. Due to the independent design and development in WSN, together with the unexpected dynamics during deployment of co-existing networks such as IEEE 802.11b/g and devices within the same frequency spectrum, it is crucial to ensure that each wireless technology maintains and provides its desired performance requirement. Therefore, a method to determine and avoid the collision between IEEE 802.15.4 and IEEE 802.11b/g devices when co-exist within a certain environment needs to be carried out.
