Wireless sensor networks have a wide variety of applications in many areas from detecting enemy targets in the military to monitoring 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 impractical to change or maintain manually these sensor networks. In this paper, we have designed and implemented a general and extendable management framework called DIstributed Self-Organizing NEtwork management (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.
