Description: Aodv for NS-2. A mobile ad-hoc network (MANET) is a kind of wireless ad-hoc network, and is a self-configuring
network of mobile routers connected wirelessly. MANET may operate in a standalone fashion, or may
be connected to the larger Internet. Many routing protocols have been developed for MANETs over
the past few years. This project evaluated three specific MANET routing protocols which are Ad-hoc
On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Dynamic MANET Ondemand
routing protocol (DYMO) to better understand the major characteristics of these routing
protocols. Different performance aspects were investigated in this project including packet delivery

Abstract. The paper analyses performance of IEEE 802.16 standard, also
known as WiMAX, when relay stations are introduced. Thanks to this feature,
coverage area and throughput of the system may be significantly enhanced. The
article defines the increase of system capacity of the relay based cell
deployment compared to a conventional single hop deployment of the same
area size. Further, the parameters that have main impact on the system with
relays and its capacity are determined.

Description: Ajey, S., B. Srivalli, et al. (2010). On performance of MIMO-OFDM based LTE systems. Wireless Communication and Sensor Computing, 2010. ICWCSC 2010. International Conference on.
4G wireless systems predominately employ multiple input multiple output (MIMO) with an orthogonal frequency division multiplexing (OFDM) system. Like other 4G systems long term evolution (LTE) also employs MIMO-OFDM physical layer. MIMO helps in increasing the throughput whereas OFDM converts a frequency selective fading channel to multiple flat fading sub-channels facilitating easy equalization. It is proposed that LTE system should mandatorily support 2Ã — 2 MIMO setup. Our paper focuses on the performance of such a LTE system with two transmit antennas and two receive antennas in a frequency selective fading environment. Platform: |

Description: In this paper we simulate a multi-hop self-organizing wireless
sensor network. The purpose of the simulation is to investigate,
quantitatively, the performance of our self-organizing network
design. In particular, we examine such parameters as network
formation time, data packet delivery performance, throughput,
and device duty cycle. In addition, we analyze the impact of
MAC and low-duty cycle protocols. We demonstrate that our
tree network has the capability of automatic network formation,
update, and recovery. The design also supports simple address
assignments and straightforward routing. We discuss our
approach, OPNET simulation design, and simulation results Platform: |

Description: Intelligent reflecting surface (IRS) is a promising
technology to enhance the coverage and performance of wireless
networks. We consider the application of IRS to non-orthogonal
multiple access (NOMA), where a base station transmits superposed signals to multiple users by the virtue of an IRS. The
performance of an IRS-assisted NOMA networks with imperfect
successive interference cancellation (ipSIC) and perfect successive
interference cancellation (pSIC) is investigated by invoking 1-
bit coding scheme. In particular, we derive new exact and
asymptotic expressions for both outage probability and ergodic
rate of the m-th user with ipSIC/pSIC. Based on analytical
results, the diversity order of the m-th user with pSIC is in
connection with the number of reflecting elements and channel
ordering. The high signal-to-noise radio (SNR) slope of ergodic
rate for the m-th user is obtained. The throughput and energy
efficiency of IRS-NOMA networks are discussed both in delaylimited and delay-tolerant transmission modes. Additionally, we
derive new exact expressions of outage probability and ergodic
rate for IRS-assisted orthogonal multiple access (IRS-OMA).
Numerical results are presented to substantiate our analyses and
demonstrate that: i) The outage behaviors of IRS-NOMA are
superior to that of IRS-OMA and relaying schemes; ii) The M-th
user has a larger ergodic rate than IRS-OMA and benchmarks.
However, the ergodic performance of the m-th user exceeds
relaying schemes in the low SNR regime; and iii) The IRS-assisted
NOMA networks have ability to achieve the enhanced energy
efficiency compared to conventional cooperative communications Platform: |
