Predicting and bounding performance is a fundamental requirement in wireless sensor network (WSN) protocol development. To support a fast development cycle principled methods are required for experimentation with wireless protocols in testbed environments that can provide repeatable performance guarantees in the target environment. In this paper we propose a method to achieve performance repeatability across test and target environments, that relies on analytical prediction of expected protocol performance as a function of RF environment parameters and forwarding protocol. For the validation of the proposed method, we present analytical, simulation, and experimental results for one-dimensional networks deployed in indoor and outdoor propagation environments, and for two-dimensional networks on four major indoor WSN testbeds to validate the performance of the proposed method on achieving repeatable protocol behavior across diverse set of RF environments.
