Abstract
Recent technological progress in microelectronics has allowed a considerable development of Wireless Sensor Networks. These networks are deployed in several relevant applications such as healthcare and wildlife which require the support of sensor nodes mobility. However, this mobility is a real threat in breaking communications and packet loss accordingly. This paper proposes a fast handover procedure based on a smart association decision to handle mobility and to ensure continuous communication in IEEE 802.15.4 WSNs. In our proposed procedure, the mobile node can anticipate the coordinator change upon detecting the degradation of the link quality indicator. Then, it performs a fast re-association based on our smart criterion and it resumes the forwarding of stored packets. Simulations show that our fast handover procedure ensures better network performances than a similar approach.
