Cross Layer Adaptation for QoS in WSN
In this paper, the authors propose QoS aware MAC protocol for Wireless Sensor networks and its cross layer extension to network layer for providing QoS in delay sensitive WSN scenarios. In WSNs, there can be two types of traffic, one is event driven traffic which requires immediate attention and another is periodic reporting. Event driven traffic is classified as Class I (delay sensitive) traffic and periodic reporting is classified as Class II (best effort) traffic. all the three schemes proposed above simultaneously.
