Hybrid Monitoring Proposal for Wireless Sensor Network

Hybrid systems and tools have been developed on several computer areas along years, for harnessing of advantages of different approaches. Monitoring is one of the goals of hybrid computer systems. However there is not a complete hybrid system for monitoring Wireless Sensor Networks (WSN) operation. This work presents a proposal of a Hybrid Monitoring System (HMS) for WSN. It consists on a combination of active and passive approaches. This achieves a complete view of WSN behavior with very low intrusion on the observed system. Active components consist on monitor nodes attached to WSN nodes. Passive component is implemented by means of a sniffer network. Data collected by both components is sent to a server for analysis and visualization. The proposed HMS provides enough information about WSN performance in order to determine sources of problems.
