Abstract:
The usage of mobile nodes is a requirement in some wireless sensor networks (WSNs) applications (wildlife or patient monitoring). They require that data packets are sent reliably, mainly as bursty traffic with low energy consumption and low latency to a base station for monitoring. Mobility of nodes introduces several communication challenges, such as frequent topological changes, intermittent connectivity, and increase in collision rate. In order to fulfill the application requirements (e.g., energy efficiency, reliable transmissions, lower end-to-end latency) low duty-cycle, mobility-aware medium access (MAC) protocols have been proposed. The paper describes the main characteristics of recent mobility-aware MAC protocols, including our protocol, highlighting their assumptions and working mechanism, their advantages and limitations. It presents concrete application constraints and protocol features for designing MAC protocols for mobility-aware WSNs. Moreover, challenges in the evaluation of the proposed MACs are discussed and prospective future directions are identified.
