One of the key issues in recent mobile telecommunication is to increase the scalability of current packet data networks. This comes along with the requirement of reducing the load of signaling related to establishment and handover procedures. This paper establishes an analytical model to analyze the signaling overhead of two different secure mobile architectures. Both are based on the Host Identity Protocol for secure signaling and use IPsec for secure data transport. The paper presents the cumulative distribution function and moments of security association periods and calculates the rate of different signaling procedures in a synthetic network model assuming M/G/∞ process for session establishments between end-nodes. Using the model, it is shown that the Ultra Flat Architecture has significant performance gains over the traditional End-to-End HIP protocol in large-scale mobile environment in the access networks and toward the rendezvous service, but performs worse in the core transport network between the GWs.
