This paper presents a high level design of a typical Ambulatory Wireless Sensor Network (AWSN) and it security requirements. It presents a theoretical analysis of the effects of mobility and dynamism of nodes in relation to the delivery of (authentication, reliability, data freshness, and integrity) services by routing protocols. The analysis focuses on Ariadne protocol and uses the Random-Way Point as the mobility model. The delivery of security services is modeled in terms of packet delivery ratios, link re-connections, and end-to-end delays. The logical analysis reveals that, the rate of node mobility and dynamism affects the delivery of security services. The paper concludes with the emerging research directions, which form the basis of the future work. Note that this is work in progress.
