EER transport protocol for Wireless Sensor Networks

Abstract

The above protocol gives near optimal results, while using minimum resources on the nodes. But the protocol shows some pitfalls in case of congestion. The EER transport protocol assumes no MAC layer contentions also each transmission is successful with probability of collision zero. In real life situations this is not true so the actual energy spent in congestion phase by nodes is different from the estimated in the EER transport protocol. Thus protocol very slowly converges from the state of congestion wasting scarce energy of sensor nodes. To nullify the above problem we analyzed the EER transport protocol considering MAC level contentions. Also we observed the behavior of the EER transport protocol in presence of different load requirements of the applications and its response in the vicinity of the different MAC layers.
