Wireless Body Area Networks (WBAN) providethe much needed transition from traditional healthcare systems to E- healthcare models. They enable the patient to perform their daily functionalities without frequent disruptions in their schedules by continuous collection of dataautomatically. Theseinformation are transmitted to thehealth care provider automatically for analysis. However, ensuring security and privacy in this process is of critical importance due to the highly sensitive nature of the information being transmitted. This work presents the Privacy Preserving Routing (PPR) modelthat includes elements to improve the security levels during transmission and also enhances the lifetime of the network by providing effective load balancing. The process of fine grained reactive routing included in the routing model ensures selection of the appropriate node to ensure high probability of packet delivery. Experiments were performed and comparisons with existing standard models indicate that the PPR model exhibits high stability levelswhich shows that the model is highly capable ofhandling sniffing attacksEnsuring high security in the delivery process.
