Abstract

We present a sensor network simulation environment that allows users to evaluate the effects of different architectural choices and strategies on the lifetime and performance of a sensor network. Our tool can also be used to evaluate new approaches (routing protocols, cooperation algorithms), and compare them with the ones already in place. This simulator is an extension of the Georgia Tech Network Simulator (GTNetS) and leverages its design choices for maximum performance. It incorporates models for the different functional units composing a sensor node and characterizes the energy consumption of each. It also has a model for a network base station and its interactions with the rest of the network. We report our results from a set of tests that demonstrate some of the capabilities of our simulator. In particular, we were able to simulate sensor networks of several hundred thousand nodes while using less than 2 GB of memory, which exceeds the capabilities of existing simulators by an order of magnitude. The simulator is also used to study the performance of an algorithm that assigns globally unique IDs to nodes in a sensor network.
