Algorithm and Architecture for Control of Wireless Sensor Networks

Sensor nodes in a Wireless Sensor Network (WSN) organize themselves into a cooperative network and perform the three basic functions of sensing, computations and communications. Energy constraints of the sensors pose a major challenge and have become an extensive research in WSN. An event driven secure topology discovery algorithm for a WSN is proposed where individual nodes are responsible for sending update messages to the base station when they detect a topological change in their own descendent sub tree. The collision between neighbour nodes has been minimized Denial of Service (DOS) threats and countered and hence the lifetime of the nodes been prolonged thereby improving the robustness of WSN.
