A Generalized Markov Chain Model for Effective Analysis of Slotted IEEE 802.15.4

by Pangun Park, Pablo Soldati, Carlo Fischione, Karl Henrik Johansson
"... Abstract—A generalized analysis of the IEEE 802.15.4 medium access control (MAC) protocol in terms of reliability, delay and energy consumption is presented. The IEEE 802.15.4 exponential backoff process is modeled through a Markov chain taking into account retry limits, acknowledgements, and unsatu ..."

An Analytical Model for the Contention Access Period of the Slotted IEEE 802.15.4 with Service Differentiation

by Eugène David, Ngangue Ndih, Nadia Khaled, Giovanni De Micheli
"... Abstract—The IEEE 802.15.4 standard is poised to become the global standard for low data rate, low energy consumption wireless sensor networks (WSN). By assigning the same sets of contention access parameters for all data frames and nodes, the contention access period (CAP) of the slotted IEEE 802.1 ..."

highpriority traffic (e.g., alarms or emergency alerts). By allowing different sets of access parameters and data frame lengths for different priority classes, this paper develops a Markov-chain-based analytical model of the CAP of the IEEE 802.15.4 MAC with service differentiation, under unsaturated traffic

Performance Analysis of Slotted Carrier Sense IEEE 802.15.4 Medium Access Layer

by Sofie Pollin, Mustafa Ergen, Sinem Coleri Ergen, Bruno Bougard, Liesbet Van Der Perre, Ingrid Moerman, Ahmad Bahai, Pravin Varaiya, Francky Catthoor , 2007
"... Advances in low-power and low-cost sensor networks have led to solutions mature enough for use in a broad range of applications varying from health monitoring to building surveillance. The development of those applications has been stimulated by the finalization of the IEEE 802.15.4 standard, which ..."

in the use of a per user Markov model to capture the state of each user at each moment in time. The key assumptions to enable this important simplification and the coupling of the per user Markov models are however different, as a result of the very different designs of the 802.15.4 and 802.11 carrier

Packet loss analysis of the IEEE 802.15.4 MAC without acknowledgements

by Feng Shu, Student Member, Taka Sakurai, Moshe Zukerman, Hai L. Vu, Senior Member - IEEE Communications Letters
"... Abstract — Transmission of the acknowledgement frame after a packet reception is optional in the IEEE 802.15.4 standard. Considering a set of sensor nodes, each of which has a packet to transmit at the beginning of an active period, we provide an analysis that yields the packet loss statistics of th ..."

"... Abstract. Here, we present the collision probability of the IEEE 802.15.4 slotted Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism over a real-time wireless sensor network (RT-WSN), also called a synchronous network system. The “backoff, ” the random delay of CSMA/CA, can be use ..."
