A Wireless Sensor Network Reliable Architecture for Intrusion Detection

An important aspect of homeland security is securing public buildings and places against intrusion. Wireless sensor networks (WSN) are an efficient means of detecting intrusion and extremely convenient to deploy in such situations. However, the software running on top of the sensor nodes that directly supports the alarm applications defined by the security forces needs to provide reliability, security and ease of use. In this paper we introduce the new concept of tinyDSM that combines distributed shared memory like behaviour with event mechanisms and a new transport protocol called DTSN which provides reliable and efficient transport of messages in WSN. Both contribute to the WSN reliability that is required for the intrusion detection application. The specific security aspects are not treated in this paper.
