“…IEEE 802.15.4 nodes, however, may still suffer from the IEEE 802.11b/g interference in case of weak IEEE 802.15.4 links, because a range in which a wireless device can cause interference to others is usually larger than that where it can be sensed by the others. This means both IEEE 802.15.4 nodes and IEEE 802.11b/g nodes can freely transmit packets without deferring for the other, which is described as an assumption called blind transmissions in [3].…”

“…• R3: Although the IEEE 802.11b transmit power is 17 dBm, only 16.9% falls into the 2 MHz band of IEEE 802.15.4 [3], i.e., 9.3 dBm. Given the CCA threshold of −85 dBm, the IEEE 802.15.4 nodes will not be able to sense the IEEE 802.11b nodes when x ≥ 94.3 dB, i.e., R3 is the region where x ≥ 94.3 dB.…”

“…While the conclusion is true in general, these studies dealt with only limited coexistence scenarios. For example, in [3], the Packet Error Rate (PER) of IEEE 802.15. 4 WSNs under IEEE 802.11b interference was analyzed based on an assumption of blind transmissions, i.e., both IEEE 802.11b and IEEE 802.15.4 nodes can transmit packets freely regardless of whether the channel state is busy or not.…”

IEEE 802.15.4 Wireless Sensor Networks (WSNs) and IEEE 802.11b/g Wireless Local Area Networks (WLANs) are often collocated, causing a coexistence issue since these networks share the same 2.4 GHz Industrial, Scientific, and Medical band. In our previous work, we built a coexistence model of IEEE 802.15.4 WSNs and IEEE 802.11b/g WLANs. By identifying three distinct coexistence regions, the model explained the coexistence behavior of IEEE 802.15.4 WSNs and IEEE 802.11b/g WLANs, and the model was experimentally validated. In this paper, we improve the model by introducing two important implementation factors: the transceiver's Rx-to-Tx turnaround time and the Clear Channel Assessment partial detection effect. The enhanced model significantly improves the accuracy on explaining and predicting the coexistence performance of IEEE 802.15.4 WSNs in the real-life environment. Furthermore, under the guidance of the model, the coexistence performance of IEEE 802.15.4 WSNs is extensively investigated in various coexistence scenarios by analysis, simulation and experiments, respectively. The simulation and experimental results agree with our analysis. The coexistence model is believed to be helpful in resolving the coexistence issue.

In this paper, we propose EasiTest, a multi-radio testbed for heterogeneous wireless sensor networks (WSN). Two types of sensor nodes, specifically, high speed multi-radio node (EZ271) and low speed single radio node (EZ521) are developed. An administration platform is provided to monitor and control the testbed. EasiTest enjoys high flexibility, powerful processing capability and ease of expansion. EasiTest provides a powerful tool not only for the study and evaluation of large scale, heterogeneous sensor networks, but also for quick prototyping of practical WSN applications. To demonstrate the capability of the testbed, we study the co-existence problem of IEEE 802.11 and IEEE 802.15.4. Guidelines are given on channel allocation and network parameter configuration to minimize the interference.

A novel method for mitigating the effects of dynamic coexistence on the operation of IEEE 802.15.4‐based mobile WSNs

Wireless networks dynamically coexist when their transmission ranges overlap as a result of mobility. Mobile wireless sensor networks (WSNs) may suffer from significant degradation of performance due to the interference caused by dynamic coexistence, which is particularly critical for health monitoring WSNs. In this paper, we propose a novel method to detect and mitigate the harmful effects of dynamic coexistence on the operation of IEEE 802.15.4-based mobile health monitoring WSNs. IEEE 802.15.4 uses the guaranteed time slots (GTS) mechanism to eliminate contention; however, successful transmissions cannot be guaranteed for coexisting WSNs. We show that using limited clear channel assessments at the beginning of the GTS enables the mobile WSNs to avoid collisions with minimum overhead. This method can also be used in combination with the previously proposed mechanisms for coexistence management. We analytically investigate the effects of using this method on the performance of the dynamically coexisting WSNs. We use OPNET simulation to investigate the coexistence of health monitoring WSNs and also to validate the proposed method. Our results indicate that using the proposed mechanism, 2-10 coexisting mobile WSNs with relatively high transmission rates (20-30% of maximum throughput) can achieve 20-90% higher rates of successful transmissions, with less than 10% increase in power consumption.Coexistence of IEEE 802.15.4-based mobile wireless sensor networks
