  Abstract

Typically, asynchronous MAC protocols are being used to monitor a significant facility for certain events or to detect an intrusion in Wireless Sensor Networks (WSN). And it can give a lot of advantages in that there is no periodic control frame. However, it has the problem of long end-to-end delay time per link caused by no precedent time synchronization, and it is not profitable at infrequent and subsequent event such as fire and intrusion. This paper introduces various wakeup period schemes and proposes a new asynchronous MAC protocol that can achieve approximated wakeup time synchronization. In this protocol, the new scheme, named Virtual Tunneling through the arbitration of wakeup time at each node, is introduced to improve the end-to-end delay and to provide enhanced QoS in multi-hop topologies with low power consumption. Additionally, it achieves protection of Virtual Tunnel by using NAV scheme. We have evaluated this protocol through comparison with the X-MAC, which is the energy efficient MAC protocol in WSN. Finally, we have evaluated experimental implementation results using the Testbed in real wide military environments.
