The in-packet Bloom filter forwarding mechanism is a source routing approach used in Information-centric networking (ICN). This mechanism is vulnerable to brute-force attacks that can be used for distributed denial-of-service (DDoS) attacks and unsolicited messages (spam). In this paper we analytically calculate the probability of brute-force attacks and(More)
In this paper, we investigate the call blocking probability calculations in the uplink of W-CDMA mobile cellular networks. In these networks, we distinguish two types of blocking, the new-call blocking, which concerns the initial call establishment request, and the handoff-call blocking, due to the users’ mobility from one cell to the other. To analyze the(More)
Secure in-packet Bloom filters is an approach used to securely forward source routing packets with small forwarding tables making the forwarding fabric resistant to unauthorized traffic. This resistance can be achieved by dynamically computing the link identifiers on the base of the packet content such as path in-out interfaces and keys of forwarding nodes(More)
Information Centric Network is a brand new architecture that focuses on the information objects rather than the location of end users. It aims to replace the current end-to-end model with the publish-subscribe model to solve many issues including security, routing scalability, mobility. One of the main features in this network is the use of a simple and(More)
The call-level performance modelling and evaluation of 3G cellular networks is important for the proper network dimensioning and efficient use of the network resources, such as bandwidth and power. In the case of the Wideband Code Division Multiple Access (W-CDMA) cellular networks, this task is complicated, not only because of the so called soft blocking,(More)
We propose a new teletraffic model, named Wireless Engset Multi-rate Loss Model (W-EnMLM) for the call-level analysis of W-CDMA networks, supporting heterogeneous service-classes of finite population of traffic sources. Quasirandom arriving calls (generated by mobile users), compete for their admission to a W-CDMA cell under the Complete bandwidth Sharing(More)
