“…With preamble sampling approaches, the transmitter sends some short preambles: the first node waking-up acknowledges the preamble and starts receiving the packet [11]. This concept is quite old and has already been proposed when considering opportunistically the routing and MAC layers together [12], or to allow fast neighbor discovery by mobile nodes with anycast [13]. Unfortunately, this approach does not increase the reliability in synchronized protocols: only one receiver would be awake at a time.…”

“…In most MAC protocols intended to handle mobility, mobile nodes aim at establishing communication links with randomly selected next-hop static nodes (e.g., ME-ContikiMAC). Such approaches can lead to increased end-to-end delay and energy consumption due to potentially longer routing paths [14]. Figure 2 illustrates those potential issues.…”

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

“…However, recently other methods have been proposed, such as opportunistic approaches where decisions are made "on the fly" [14][15] [16]. Also, the use of mobility awareness in WSNs where mobility is utilised, has been suggested as a possible approach [17] [18] [19]. In this regard, approaches such as the prediction of mobility patterns of mobile nodes has been proposed in order to improve routing and data delivery in the network [20].…”

“…These studies all have validity in terms of network layer packet delivery when a MSN is in use. However, IT is the MAC layer which is responsible for the greatest amount of energy consumption [18]. As such, there is potential in the use of mobility patterns at the MAC layer in relation to channel access, and the duty cycling utilised therein.…”

In Wireless Sensor Networks (WSNs) the use of Mobile Sink Nodes (MSNs) has been proposed in order to negate the "hotspot" issue. This where nodes closest to the sink node shall run out of energy fastest, affecting network lifetime. However, in using an MSN there remains the issue of nodes that sink passes closest to using most energy. In this study we propose a novel Mobility Aware Duty Cycling Algorithm (MADCAL), for use at the MAC layer. This algorithm provides a lightweight solution, utilising knowledge of the mobility pattern of the sink node in order to determine a dynamic communication threshold, within which static nodes shall awaken to communicate with the sink. This avoids the need for energy-heavy beacon messages. Using the Omnet++ simulation framework and tested on a lightweight implementation of a Carrier-sense multiple access (CSMA) based MAC protocol, we demonstrate a reduction in energy consumption up to 15% and up to 300% increase in frame delivery to the MSN, when compared to the existing duty cycling approach.
