In this paper, the effect of channel conditions on the global behavior of a wireless Visible Light Communications (VLC) optical network are studied. It presents a system-level simulator that considers jointly a channel propagation model and the MAC mechanisms to have a realistic description of the network, even in situations where the emitted signal is heavily affected by reflections in any close surface or obstacle. The resulting platform also accurately evaluates both Line-Of-Sight (LOS) and Non-LOS (NLOS) contributions on each node and enables the effective use of Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) schemes as defined by IEEE 802.15.7r1 standard, as well as allows a correct evaluation of lifelike problems such as the effect of hidden nodes. This work shows the necessity of accurately modeling VLC MAC layer performances, taking also into account the physical nature of visible light propagation in indoor scenarios.

The IEEE 802.15.4 standard is designed for low-power and lowrate wireless Personal Area Networks. Although energy is a key parameter in shaping the communication and interaction methods of wireless sensor nodes, the specification of the MAC layer doesn't embed enough information for energy and mobility support. For instance, using the IEEE 802.15.4 beacon frames, a node will be able just to discover whether other peers are powered by mains or are they fully or reduced functional devices. However, sensors nodes are able to gain power by different means including: rechargeable batteries, moving sensor charger, ambient or renewable energy, or a combination of these methods. To address these issues, we propose an extension of the IEEE 802.15.4 frame formats to support mobility and embed new energy powering modes and levels. We discuss how the MAC layer extensions could be used to optimize device discovery and routing processes in IEEE 802.15.4 based wireless sensor networks.

“…Moreover, authors adopt the Time Division Multiple Access (TDMA) mechanism to access the medium. Authors in this paper [7], propose an idea of extended IEEE 802.15.4 superframe structure by considering both the PCF and DCF modes. The performance in terms of throughput and data delivery ratio is examined.…”

Due to low power consumption and low duty cycle, IEEE 802.15.4 standard is widely used for Low Rate Wireless Personal Area Networks (LR − W P ANs). It works in Beacon Enabled (BEn) and Non Beacon Enabled (NBEn) mode. In BEn mode, it has Contention Access Period (CAP) and an optional Contention Free Period (CFP). During CAP, nodes contend to access the medium for communication while CFP period provides Guaranteed Time Slot (GTS) for low latency and applications requiring specific bandwidth. In this paper, we evaluate the comprehensive energy consumption of slotted CSMA/CA algorithm of IEEE 802.15.4 standard during idle and backoff periods. Simulation results with acknowledgment frame are given at the end of the paper.
