“…Given this situation, each device can experience interference from the transmissions on the other network (Shin et al 2007), degrading performance and leading to packet loss. IEEE 802.15.4 standards recommend using the clear channels where the energy of the Wi-Fi network is typically lower (Hubler 2005); however, if many IEEE 802.15.4 devices are operating in the area, using the clear channels may not ensure that interference is avoided (Shin et al 2007). Two sets of tests were conducted with the sensor nodes placed 7.6 meters, or 25 feet, and operating at full radio power (Power Level 31).…”

The Newmark Structural Engineering Laboratory (NSEL) of the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign has a long history of excellence in research and education that has contributed greatly to the state-of-the-art in civil engineering. Completed in 1967 and extended in 1971, the structural testing area of the laboratory has a versatile strong-floor/wall and a three-story clear height that can be used to carry out a wide range of tests of building materials, models, and structural systems. The laboratory is named for Dr. Nathan M. Newmark, an internationally known educator and engineer, who was the Head of the Department of Civil Engineering at the University of Illinois and the Chair of the Digital Computing Laboratory . He developed simple, yet powerful and widely used, methods for analyzing complex structures and assemblages subjected to a variety of static, dynamic, blast, and earthquake loadings. Dr. Newmark received numerous honors and awards for his achievements, including the prestigious National Medal of Science awarded in 1968 by President Lyndon B. Johnson. He was also one of the founding members of the National Academy of Engineering. Contact:Prof ABSTRACTA critical aspect of using wireless sensors for structural health monitoring is communication performance. Unlike wired systems, data transfer is less reliable between wireless sensor nodes due to data loss. While reliable communication protocols are typically used to reduce data loss, this increase in communication can drain already limited power resources. This report provides an experimental investigation of the wireless communication characteristics of the Imote2 smart sensor platform; the presentation is tailored towards the end user, e.g., application engineers and researchers. Following a qualitative discussion of wireless communication and packet delivery, a quantitative characterization of wireless communication capabilities of the Imote2 platform is provided, including an assessment of onboard and external antenna performance. Herein, the external antenna was found to significantly outperform the onboard antenna in both transmission and reception reliability. However, the built environment, including building materials and other wireless networks, can significantly reduce reception rate and thus increase packet loss. Finally, implications of these results for a full-scale implementation are presented. CONTENTS

“…In [22], the authors performed mathematical analysis for the coexistence of WLAN and ZigBee network under some specific MAC and network settings. Specifically, this work assumed that the clear channel assessment (CCA) mode 2 is employed where each network node can only detect the transmission of other nodes of the same network (transmissions from WLAN nodes are transparent from or cannot be detected by ZigBee nodes and transmissions from ZigBee nodes are transparent from or cannot be detected by WLAN nodes).…”

Wireless personal area networks (WPAN) and wireless local area networks (WLAN) based on IEEE 802.15.4 and 802.11 standards operate in overlapping unlicensed frequency bands; therefore, they create harmful interference for each other if deployed in the same geographical area. There has been various performance analysis of the media access control (MAC) protocols for both networks individually. However, the coexistence performance of the two networks is less well-understood, which has been mainly studied via computer simulation. In this paper, we attempt to close this gap by developing a comprehensive mathematical model to evaluate the throughput performance of the carrier sense multiple access with collision avoidance (CSMA/CA) protocols of coexisting 802.15.4 WPAN and 802.11 WLAN. Specifically, we consider two coexistence scenarios, called symmetric and asymmetric scenarios. In the symmetric scenario, wireless nodes in both networks can sense one another while in the asymmetric scenario, only WPAN nodes can sense active WLAN nodes but WLAN nodes cannot sense the transmissions from WPAN nodes. The proposed models effectively resolve the major challenge arising from the fact that the MAC protocols in the two networks operate in different time scales. In addition, we explicitly capture detailed operations and interactions of the underlying MAC protocols. We then propose to employ the developed models for channel allocation to achieve fair throughput sharing among WPAN nodes. Numerical results confirm the excellent accuracy of the proposed models and their usefulness for performance evaluation and design of the heterogeneous network.

“…The performances of IEEE 802.15.4-based low rate wireless personal area networks (LR-WPANs) are seriously degraded about 10∼100% due to the interference from wireless local area networks (WLANs) reported in [1], [2]. To resolve the issue, most methods proposed in [3]- [5] abandon the interfered-channels and switches a non-interfered channel being already used by other piconets.…”

SUMMARYTo reduce perforamnce degradations of LR-WPANs due to interference from WLANs, this letter proposes a protocol to allow a piconet to switch an operating channel to an interference-free channel only for transmitting beacon frames. The proposed method does not only increase network performances because of hgh reliability of the beacon frames, but also increase overerall channel utilizations because of using even interfered-channels.
