A Mobility-Supporting MAC Scheme for Bursty Traffic in IoT and WSNs

Abstract

International audienceRecent boom of mobile applications has become an essential class of mobile Internet of Things (IoT), whereby large amounts of sensed data are collected and shared by mobile sensing devices for observing phenomena such as traffic or the environmental. Currently, most of the proposed Medium Access Control (MAC) protocols mainly focus on static networks. However, mobile sensor nodes may pose many communication challenges during the design and development of a MAC protocol. These difficulties first require an efficient connection establishment between a mobile and static node, and then an efficient data packet transmissions. In this study, we propose MobIQ, an advanced mobility-handling MAC scheme for low-power MAC protocols, which achieves for efficient neighbour(hood) discovery and low-delay communication. Our thorough performance evaluation, conducted on top of Contiki OS, shows that MobIQ outperforms state-of-the-art solutions such as MoX-MAC, MOBINET and ME-ContikiMAC, in terms of significantly reducing delay, contention to the medium and energy consumption

Internet of Mobile Things: Overview of LoRaWAN, DASH7, and NB-IoT in LPWANs Standards and Supported Mobility

“…One of the most attractive applications in IoT is the medical and healthcare [16], [17], [20], [21]. Usually, when we address this subject, readers think of the wearable devices that are used to remotely monitor the health of the patient, fitness programs, elderly care, and trace a chronic disease.…”

“…This growth is expected to continue to be exponential over the next decade, which introduces a rise in "Big Data" [8], energy consumption [9] and devices per cell [10]. Today, a wide range of data acquisition devices is already implemented in IoT applications [11], [12], that require mobility such as smart cities [13][14][15], health-care [16], [17], smart vehicles [18], aging society [19], hospital [20], [21], and in post-emergency networks [22]. In such applications, the requirements for mobility, low latency, and long-range communication are significantly considerable [23].…”

FM‐MAC: A fast‐mobility adaptive MAC protocol for wireless sensor networks

“…Another improvement of M-ContikiMAC, ME-ContikiMAC, and MobiXplor is presented by MobIQ, 36 which proposes a novel neighbor discovery mechanism to achieve efficient handovers for MNs when transmitting data in burst mode. To achieve this, the MN continuously anycasts specific control packets during the preamble phase to assure that all neighbors receive them.…”
