The results demonstrate that WiMAX is the most suitable network among the considered networks for connecting PECC nodes with BEH main server, and further connecting main server with a doctor on the move. It is also deduced that for a given set of QoS parameters, WiMAX supports a load capacity of 22,000 packets at center nodes and the main server and it performs well even when the mobility speed of doctor exceeds 200 KPH.
