Measuring Effective Capacity of IEEE 802.15.4 Beaconless Mode


IEEE 802.15.4 is an emerging wireless standard addressing the needs of Low-Rate Wire- less Personal Area Networks with a focus on enabling various pervasive and ubiquitous applications that require interactions with our surrounding environments. In view of the application potential of IEEE 802.15.4, knowing the fundamental network properties soon becomes essential in fasten the interactivity between these devices. Among all, knowing e®ective capacity of a path in wireless networks is of particular importance in routing and tra±c management. In this paper, we implement SenProbe, a recently proposed path ca- pacity estimation tool specially designed for the multi-hop ad hoc wireless environment. We present an implementation of SenProbe in Sensor Operating System (SOS), and evaluate the behavior/e®ectiveness of SenProbe in various testbed setups; including an interfered setting that cannot be simulated. Experiment results validate the workings of SenProbe and o®er insights into how the capacity of a wireless path changes in real wireless environments. Our e®orts provide a basis for realistic results that can be of assistance in activities such as capacity planning, protocol design, performance analysis, and etc.
