    ABSTRACT
    The recent advances in the application of Software Defined Networks
    (SDN) concepts in Wireless Sensor Networks (WSNs) leads the
    implementation of centralized algorithms. In this work, the SDN
    concept is considered, together with two routing procedures, with
    the purpose of disjoint paths generation, aiming to extend WSN’s
    lifetime. Both approaches are based on Dijkstra algorithm for the
    selection of minimum paths. The first approach allocates distinct
    paths for various flows towards the same destination. The second
    one, penalizes computed paths using an adaptive cost function.
    Simulation results are performed using the Cooja sensor network
    simulator.
