چکیده
The fourth generation (4G) of mobile telecommunication technology provides ultra-band internet access for mobile devices such as smartphones, tablets, and laptops. One of the challenges in the Long Term Evolution (LTE) 4G networks is the low data rate for cell-edge users as well as coverage gaps. In this paper, we define and evaluate models for analysis of performance of mobile networks architectures defined by 3GPP. We used the Discrete-Event System Specification (DEVS) formalism to model the mobile networks and implement the framework. The proposed model implements the deployment layout of the Base Station (BS) cellular antennas, and it manages the distribution and movement of the User Equipment (UE) devices. The model calculates the Propagation for each BS, as well as the pathloss in the links between BSs and the UEs in the range. It also computes the power received by the BS and the UE in each link. These results will be used in the design of models for Coordinated Multipoint approach in delivering faster data.

A New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
