Abstract: This paper proposes the distributed cooperation model (DCM) based hierarchical smart routing protocol (HSRP) to counter the denial of sleep (DoSL) attacks in Green Wireless Sensor Networks (GWSNs). DCM solution combined with the Dynamic Elliptic Curves-RSA (DECRSA) algorithm is used to provide high security level and protect Wake-Up Radio (WUR) for GWSNs against DoSL attack targeting the energy resources of sensors. The used distributed schema ensures the load balancing in the network through the selection of a new Supervisor Node at the beginning of each round based on a special equation taking into account different metrics such as the remaining energy and the number of neighbour nodes. Simulation results conducted under the NS3 simulator show that the proposed DCM helps to effectively protect the GWSNs against the DoSL attacks and improves the network lifetime by more than 60% when three malicious nodes are used. Obtained results show also that the DCM extends either the period of stability and instability to the maximum and helps to counter the fall in the number of alive nodes which cause the problem of isolated area.
