Mobile wireless sensor networks (MWSNs) have become a foremost solution in many emerging applications both in industry and academia. Moreover, considering the mobile node in WSN is a challenging task to designing efficient communication protocols, specifically at a medium access control (MAC) layer. Most of the existing protocols consider only for static and slow mobility. To meet with future MIoT applications, in this paper we propose Enhanced Energy Efficient Mobility aware MAC (EMM-MAC) protocol. Our EMM-MAC protocol consists of 3 contributions i) static synchronization and mobility handling phase to support both environments, ii) By using queue length-based channel access priority for static nodes, and iii) the combined highest signal strength and node status-based channel access priority for mobile nodes without any control packet overhead. The simulation results verify that EMM-MAC yields a notable improvement in the average power consumption, packet latency, and packet delivery ratio performances against the well-known mobility-aware MAC protocols under different mobility models and environments.

“…The MS-SMAC 27 tries to improve MS-MAC by introducing a specific mobility prediction algorithm that responds actively to the MN speed variation to update the MN schedule in advance but at the expense of additional overhead. While moving, an MN periodically broadcasts information about its speed and direction.…”

“…In this part, we evaluate and compare the performance of the proposed FM-MAC protocol against some well-known mobility-aware MAC protocols, ie, AM-MAC, 28 EMS-MAC, 29 MT-MAC, 30 MS-SMAC, 27 as well as the CSMA/CA protocol. The CSMA/CA is a nonenergy-saving MAC, but, it is used here only as a reference protocol for comparison purpose.…”

As a subset of the internet of things, wireless sensor networks (WSNs) are increasingly composed of mobile nodes (MNs) to meet the emerging needs.However, nodes mobility presents significant challenges to the design of effective communication protocols, especially at the medium access control (MAC) sublayer. Interestingly, the existing mobility support MAC solutions consider only scenarios requiring slow mobility. Nowadays, some WSN applications require employing high-speed MNs for some specific tasks. Consequently, the mobility impact is sharp as the existing solutions could no longer guarantee the quality-of-service requirements. To deal with high-speed mobility, we propose in this paper a fast-mobility adaptive MAC (FM-MAC) protocol. The FM-MAC protocol adopts the contention-based access approach and introduces new mechanisms to enhance both mobility and communication management in WSNs. Our proposal consists of four contributions, ie, (1) an improved algorithm for autonomous mobility-detection, (2) a new intercluster handover mechanism, (3) a priority-based contention mechanism prioritizing MNs to access the medium, and finally, (4) a multichannel communication strategy intended to enhance the throughput and communication management aspects. Extensive simulations are conducted to compare FM-MAC protocol with existing well-known mobility-aware MAC protocols. Results and discussion disclose that FM-MAC performs better in both static and mobile scenarios in terms of reliability, latency, and energy saving. As expected, the advantage of FM-MAC over its counterparts becomes more evident as the mobility speed increases.Trans Emerging Tel Tech. 2020;31:e3782.wileyonlinelibrary.com/journal/ett

“…This means that in bad channel conditions any losses are kept to a minimum and good channel conditions are taken advantage of by transmitting more data. [8] is similar to MS-MAC in its scheduling, however it requires the use of known static nodes to transmit messages to the mobile nodes, such that the mobile nodes can determine their speed more accurately. In this way it allows mobile nodes to indicate to its neighbours when its speed has changed and then update the synchronisation frequency accordingly.…”
