Wireless sensor networks are envisioned to support an increasing number of applications having various Quality-of-Service (QoS) requirements. A possibility to provide a large variety of QoS is to deal with multi-stack WSN where several routing and MAC protocols coexist in the same network. However, routing loops can occur when several routing protocols are used alternatively. Such loops can yield to large delays and high packet loss and should therefore be avoided. In this paper, the authors propose a three-step solution to solve the loop problem.
