Abstract
Many Wireless Sensor Network applications such as healthcare and wildlife monitoring require the support of nodes mobility. However, the mobility has large impact on the network behavior namely the dynamic network topology and the synchronization loss of mobile nodes. Given that, this paper proposes two new re-association procedures for reliable handover to deal with nodes mobility in IEEE 802.15.4 WSNs. In the first approach, the handover process is triggered by parent nodes based on their residual energy. In the second approach, the handover process is triggered by mobile nodes upon location change. Both approaches allow to minimize data packet loss during the handover process while optimizing energy consumption. We used simulation in order to highlight the efficiency of our proposals namely in terms of network throughput and reliability.
