Abstract. Wireless technology has been seen as the communication technology of the future. One of many challenges is the support for predictability and time-bounded communications over this technology. In this way, the control of temporary partitions, called inaccessibility, is of fundamental importance. For this reason, this paper makes a characterization of inaccessibility in wireless networks and describes an exhaustive study about it on IEEE 802.15.4 wireless standard. The knowledge of inaccessibility incidents and their duration is a first step to define means to control network partitioning and therefore to form a basis for supporting real-time communications over wireless technology.

“…In [19], the authors proposed to employ renewal theory for analysis of the slotted non-persistent IEEE 802.15.4 MAC. The authors in [20] invented another analytical Markov chain (MC) model for the unsaturated slotted carrier sense multiple access with collision avoidance (CSMA/CA) of the IEEE 802.15.4 MAC considering the superframe structure. The MC model for throughput analysis of saturated and unsaturated IEEE 802.15.4 networks was developed in [21].…”

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 first approach is inspired from the seminal work of Bianchi on the analysis of IEEE 802.11 [4], and is based on modelling the behavior of a sensing node using a Markov chain. The most relevant contributions along this approach are [5], which adapts Bianchi's model to the specific contention access procedure of the slotted IEEE 802.15.4 CAP under unacknowledged saturated traffic conditions, [6] which corrects the analysis in [5] and extends it to include acknowledgment transmission, and [7] which proposes a more complex model reflecting additionally the superframe structure under unsaturated traffic conditions. A final relevant contribution, upon which our work is based, is the work of Ramachandran et al [8] which develops a framework based on two Markov chains; the Node-State chain to determine the frac-tion of time a node spends in different states and the Channel-State chain to calculate the throughput of the network.…”

The IEEE-802.15.4 standard is poised to become the global standard for low data rate, low energy consumption Wireless Sensor Networks. By assigning the same sets of contention access parameters for all data frames and nodes, the Contention Access Period (CAP) of the slotted IEEE-802.15.4 currently provides an even channel access functionality and no service differentiation. However, some applications may require service differentiation and traffic prioritization support to accommodate high-priority traffic (e.g., alarms). In order to simulate a scenario in which different sets of access parameters for different node classes can be configured, this paper develops a Markov-chainbased model of the CAP of the IEEE-802.15.4-MAC. Our Markov model can be used to evaluate the impact of mixing node classes in important factors like the throughput, energy consumption, probability of delivery and the packet latency. The model has been used to provide traffic differentiation in a high saturation scenario in which a set of nodes can be configured to increase 76% the probability of sending a packet and reduce 58% latency, with a 69% energy penalty, in comparison with a standard scenario. The accuracy of the Markov model is validated by extensive ns-2 simulations.
