JSensor: A Parallel Simulator for Wireless Sensor Networks and Distributed Systems

In this paper, we present a sensor network simulator called JSensor which executes parallel simulations for shared memory or multi-core architectures. JSensor allows synchronous and asynchronous large sensor networks simulations. In our test scenarios we consider flooding data propagation. In experiments, the application code level of concurrence on shared memory hardware is close to $90%$, the speed-up is nearly linear when the number of computer cores is increased, and the runtime function is nearly linear when the number of nodes is increased until five hundred thousand nodes.
