The analysis of WLAN/3G interworking access based on a mobility model

Analysis of an adjacent 3G network corruption influence on WLAN/3G interworking access

“…It should be noted that any cell corruption in a LA results in a cell category change in it. In [7], as Fig. 1(c), the contribution is the performance evaluation of the network (i.e., from the user entrance to the WLAN cell point of view) against the attack.…”

“…It gives us the average number of times (i.e., ) that a mobile user enters to the WLAN cell, while performing a random walk in the LA and ALAs. Also as [7], there is an assumption that users are distributed all over the LA0. In other words, users' movements start from LA0 but their movements paths can pass through other LAs.…”

“…1. (a) A common symmetrical cell model [8] (b) A common symmetrical cell model used in this paper (c) Cell categories for the studied model in [7] (d) values in attack conditions (for different steps) for the studied model in [7]. Regular Markov chain model is applied to evaluate this arrival [2][3].…”

“…Also, some 3G networks which are independent of the studied network are considered as Adjacent LAs (ALA). In [7], we analyzed the average number of times of user entry to the WLAN cell when an attacker corrupts a typical 3G cell in the studied network. Here, we estimate this parameter when an attack with the aim of a 3G cell coverage failure has been happened in an ALA.…”
