Analytical Model for Delay Distribution of PRMAC

Delay is one of the most important parameters of interest while providing QOS guarantees for Wireless Sensor Networks (WSN). Various MAC layer protocols for WSN have been proposed for efficient management of delay. Analyzing single hop and end to end delay using queuing analysis can provide significant help in modeling various real time WSN applications. This paper parameterizes the cross-layer analysis framework for investigating the single hop delay distribution of a cross layer WSN MAC protocol PRMAC. The analysis demonstrates how the methodology can be applied to a cross layer protocol embedding key details of the protocol such as impact of control packets (PION) modeling. An example of the analysis is illustrated using a single hop delay for a node with a small buffer.
