Medium Access Control based on Adaptive Sleeping and Probabilistic Routing for Delay Tolerant Mobile Sensor Networks

摘要

The paper proposes a medium access control (MAC) scheme with coordinated and adaptive wakeup scheme designed for delay tolerant mobile sensor networks (DTMSNs). Many applications motivate MAC schemes for DTMSNs that are different from traditional wireless MAC such as IEEE 802.15.4 in several ways: energy conservation and average delay. MAC with coordinated and adaptive wakeup scheme protocol uses a few novel techniques to reduce energy consumption and message overhead rates. It can reduce significantly control overhead and adaptively wake up, and it avoids overhearing unnecessary traffic. Finally, in this paper, simulation applies message passing to reduce contention latency for applications that require in-network data processing. Simulation results show that MAC with Adaptive Sleeping and based on Probabilistic Routing protocol (MAC-ASPR) obtains significant energy savings compared with IEEE 802.15.4 and S-MAC.
