In this paper, we analyze the performance limits of the slotted CSMA/CA mechanism of IEEE
802.15. 4 in the beacon-enabled mode for broadcast transmissions in WSNs. The motivation …

The IEEE 802.15. 4 protocol proposes a flexible communication solution for low-rate
wireless personal area networks including sensor networks. It presents the advantage to fit …

The IEEE 802.154 standard is designed as a low power and low data rate protocol offering
high reliability. lt defines a beaconed and unbeaconed version. In this work, we analyze the …

In this paper, we propose an analytical Markov chain model of the slotted carrier-sense
multiple-access/collision-avoidance (CSMA/CA) protocol for IEEE 802.15. 4 under …

Supported by IEEE 802.15. 4 standardization activities, embedded networks have been
gaining popularity in recent years. The focus of this paper is to quantify the behavior of key …

The IEEE 802.15. 4/ZigBee protocols are gaining increasing interests in both research and
industrial communities as candidate technologies for Wireless Sensor Network (WSN) …

Network games are becoming increasingly popular, but their traffic patterns have received
little attention from the academic research community. A better understanding of network …

In this paper, we propose a Markov chain-based analytical framework for modeling the
behavior of the medium access control (MAC) protocol in IEEE 802.15. 4 wireless networks …

In this paper, we propose two mechanisms, ie, 1) backoff exponent differentiation (BED) and
2) contention window differentiation (CWD), to provide multilevel differentiated services for …
