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. Quasi-random arriving calls (generated by mobile users), compete for their admission to a W-CDMA cell under the Complete bandwidth Sharing(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)
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)
Information centric networking is a new concept that places emphasis on the information items themselves rather than on where the information items are stored. Consequently, routing decisions can be made based on the information items rather than on simply destination addresses. There are a number of models proposed for information centric networking and it(More)
