We propose a management system for wireless sensor networks based on EPCglobal Reader Management. Reader Management protocol is the standard network management protocol that use the exchange of SNMP message between managed device and management system. Extending the Reader Management protocol to manage WSNs, we are able to get an integrated management view point of heterogeneous WSNs. However, a sensor node which construct local network is incapable of supporting TCP/IP based stack due to resource constraints environment. For solving this problem, we propose that base station only work SNMP agent and represent other sensor nodes.
