Wireless sensor networks have a wide variety of applications in many areas from detecting enemy targets in the military to moni- toring patient health or water/gas usage in the civil. However, sensor devices are usually equipped with a limited power battery and deployed at a very high density in inaccessible environments. Therefore, it is im- practical to change or maintain manually these sensor networks. In this paper, we have designed and implemented a general and extendable man- agement framework called DIstributed Self-Organizing NEtwork man- agement (DISON) framework to provide an autonomous management mechanism for WSNs. In DISON, sensor nodes exploit local knowledge or cooperate with other nodes to coordinate and adapt management and application tasks effectively according to their capabilities. To verify the efficiency of the proposed framework, we have evaluated DISON in a data collection application scenario, where DISON is used to optimize the number of active nodes. The simulation results show that running DISON reduces the energy consumption up to 30%, and also improves other key parameters such as the packet delivery rate and the end-to-end delay. With the rapid development of technologies in IC (Integrated Circuit) and MEMS (Microelectromechanical systems), Wireless Sensor Networks (WSNs), networks of tiny sensor devices, have been extensively used nowadays in various applications such as target tracking, habitat monitoring and many others. How- ever, sensor nodes have very limited power and resource constraints. Therefore, they are prone to fail. The sensor failure may cause changes in network topology and affect the quality of offered services. Moreover, sensor nodes can be deployed in a large number of nodes and in inaccessible environments depending on the application. Thus, the manual replacement of failed sensor nodes is impossible or expensive. To cope with these challenges, the development of self-organizing management functionalities in WSNs is desirable. Due to the limited resource nature of sensor nodes, a management system for WSNs needs to be lightweight, autonomous and scalable. In addition, the
