The usage of mobile sink or sensor nodes may improve the performance of some wireless sensor network (WSN) applications, such as wildlife monitoring. Mobility of nodes brings forward communication challenges such as link disconnections, frequent topological changes, increase in collision rate and handover delays in energy-constrained WSNs. To handle media access issues, WSN researchers have proposed...
Mobility of nodes in wireless sensor networks (WSNs) has raised a number of research questions particularly those related to media access, handover mechanism, reliability and latency. To address challenges such as handover delays, energy efficiency and channel contention, mobility-aware media access protocols have been proposed. This paper presents the state-of-the-art in the field of MAC protocols...
