562 Abstract— Reconfigurable hardware module for Automatic digital Modulation Identification (AMI) scheme has been developed and presented in this paper. The proposed module has been developed using Matlab/Simulink and implemented on Xilinx Virtex v3200efg1156 FPGA device. The synthesis and test results show that the power required to implement the module is 466 mW and the propagation delay is ...

IEEE 802.16 WiMAX is a promising new wireless technology for providing broadband ubiquitous network access. As more and more researchers and industrials are interested in simulating such networks, a number of WiMAX simulators have been emerged in the networking community. One of the most recent WiMAX simulator is the one developed for ns-3. This module provides a standard compliant and well des...

RLWM Model RLWM includes two modules, a classic incremental RL module with learning rate a, and a WM module that can learn in a single trial (learning rate 1) but is capacity-limited (with capacity K). The WM module is also subject to forgetting. The final action choice is controlled by weighing the contributions of the RL and WM modules’ policies. How much weight is given to WM relative to RL ...

Due to its potential for multi-gigabit and low latency wireless links, millimeter wave (mmWave) technology is expected to play a central role in 5th generation (5G) cellular systems. While there has been considerable progress in understanding the mmWave physical layer, innovations will be required at all layers of the protocol stack, in both the access and the core network. Discrete-event netwo...

Thanks to the wide availability of bandwidth, the millimeter wave (mmWave) frequencies will provide very high data rates to mobile users in next generation 5G cellular networks. However, mmWave links su er from high isotropic pathloss and blockage from common materials, and are subject to an intermittent channel quality. Therefore, protocols and solutions at di erent layers in the cellular netw...

The correct implementation of the protocols and proper exchange of messages is very important for an easy comparison of the results of real measurements and network simulations. This work shows the validation of the ns-3 802.11s mesh module with respect to the actual IEEE Standard 802.112012 [3] and proposes changes which are needed to get the ns-3 implementation compliant to the actual standar...

This paper presents the first IEEE 802.16m medium access control (MAC) protocol module embedded in the network simulator version 3 (ns-3). The designed module provides a validation tool for researchers to verify simulated results related to the IEEE 802.16m. This module supports the basic MAC functions which includes an initial ranging (IR) function; four types of bandwidth request (BR) procedu...

Mobility management is becoming an important issue day by day due to the immense proliferation of wireless access networks globally. The IETF has standardized Mobile IPv6 (MIPv6) to handle user mobility in IP-based mobile data networks. Worldwide the researchers are putting in a lot of effort to render the mobility management as seamless as possible in order to enhance user experience. These re...

In this paper, we present a novel scheme for the multicast transmission of data over Universal Mobile Telecommunications System (UMTS) networks. Apart from the normal multicast transmission over UMTS, we consider the handling of exceptional cases caused by user mobility scenarios. The proposed scheme is in accordance with the current specifications of the Multimedia Multicast/ Broadcast Service...

Network Simulator 3 (NS-3) enables the interaction of simulated network nodes with real ones through the use of special emulated network devices (EmuNetDevices) and real time execution. A virtual node can use an EmuNetDevice to bind its network device to a real network device of the computer hosting the simulation; however, the real network device must operate at MAC layer and be persistent. Th...
