Optimal p-Persistent MAC Algorithm for Event-Driven Wireless Sensor Networks
2008 Next Generation Internet Networks
In event-driven wireless sensor networks nodes transmit information only if the monitored physical magnitude levels have triggered an alarm. In these networks, traffic exhibits a high spatial correlation, since it is likely that neighbor nodes detect and try to notify the same events. Thus, the probability of packet collision raises up, as well as notification delay, just as opposite as required. In this work we propose to use a ppersistent mechanism in the access control layer.
