DRMA: A Dynamically Reconfigurable Management Architecture for Wireless Sensor Networks

Wireless sensor networks (WSN) is uniquely characterized by its limited resources and often deployed in remote and harsh environments. It is highly dynamic, prone to faults and usually kept unattended. Therefore, proper management of WSN and its limited resources is highly desirable for an effective and efficient functioning of the network. By introducing state machines and publish/subscribe scheme, a light-weight and dynamically reconfigurable management architecture for WSN is proposed, which is called DRMA. By dynamically configuring the data collection mode and processing method, it supports application dynamics and new application additions, which in practice are very desirable to make applications better meet a big diversity of real needs. The result of simulation shows that DRMA can collection and process data timely and accurately.
