The hotspot issue in wireless sensor networks, with nodes nearest the sink node losing energy fastest and degrading network lifetime, is a well-referenced problem. Mobile sink nodes have been proposed as a solution to this. They do not completely remove the hotspot problem though, with nodes the sink passes most closely still expending more energy than others. This study proposes a lightweight algorithm, located in the media access control (MAC) layer of static nodes and utilising knowledge of predictable sink node mobility. This is in order to create a dynamic communication threshold between static nodes and the sink, within which static nodes awaken, lessening competition for sink communication between nodes. In utilising predictable mobility and factors already known to the static node, such as location and interference range, there is no need for energy-consuming messaging. Analysis and simulation results, tested on a lightweight implementation of a carrier-sense multiple-access-based MAC protocol, show a significant improvement in energy consumption in both controlled and random environments, with frame delivery improved to the point where sink speed is negated. This is when compared to the existing duty cycling approach.

“…In this paper we propose a novel mobility-aware duty cycling algorithm (MADCAL) [27], to utilise the mobility pattern of the MSN in order to positively affect the wake-up schedules of static nodes. MADCAL operates at the MAC layer, independent of any routing protocol and uses no extra beacons or messages.…”

“…Thus, the role of hotspot is spread across several nodes in the network, rather than just those who would be closest to the sink if stationary. These nodes are termed as significant nodes [12,13]. Mobile sink nodes (MSNs) are utilised in various applications, such as within vehicles, located on robots or merely carried by a person.…”

“…As such, this work utilises the dynamic communication threshold between a MSN and static sink developed in our original study, the Mobility Aware Duty Cycling Algorithm (MADCAL) [12,13], with predictable sink mobility. Within a static, significant node, the move from the SLEEP function to clear channel assessment (CCA) only occurs when the sink node is within the threshold of the static node.…”

Utilising the mobilisation of a sink node in a wireless sensor network to combat the energy hole, or hotspot issue, is well referenced. However, another issue, that of energy spikes may remain. With the mobile sink node potentially communicating with some nodes more than others. In this study we propose the Mobility Aware Duty Cycling and Dynamic Preambling Algorithm (MADCaDPAL). This algorithm utilises an existing solution where a communication threshold is built between a mobile sink node using predictable mobility and static nodes on its path. MADCaDPAL bases decisions relating to node sleep function, moving to clear channel assessment and the subsequent sending of preambles on the relation between the threshold built by the static node and the position of the mobile sink node. MADCaDPAL achieves a reduction in average energy consumption of up to 80%, this when used in conjunction with a lightweight carrier-sense multiple access based MAC implementation. Maximum energy consumption amongst individual nodes is also brought closer to the average, reducing energy spikes and subsequently improving network lifetime. Additionally, frame delivery to the sink is improved overall.
