Description: The interworking between heterogeneous third-generation cellular networks and wireless local area networks is one promising evolution approach to fourth-generation wireless networks, which can exploit the complementary advantages of the cellular network and WLANs.. This article deals with a policy framework for resource management in a loosely coupled cellular/WLAN integrated network, where load balancing policies are designed to efficiently utilize the pooled resources of the network. A two-phase control strategy is adopted in the load balancing policy, in which call assignment is used to provide a statistical quality of service guarantee during the admission phase and dynamic vertical handoff during the traffic service phase there by minimizing the performance variations.-The interworking between heterogeneous third-generation cellular networks and wireless local area networks is one promising evolution approach to fourth-generation wireless networks, which can exploit the complementary advantages of the cellular network and WLANs..

Description: Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier.
A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air).
The sensor nodes are deployed randomly in the environment to be monitored.
The sensor nodes distributed in ad hoc structure.
In WSN there is no base station and not all nodes hear each other.
The WSN is a multi-hop network.
Basic part of my code is to randomly place the sensor nodes in the given space then connecting each two nodes if the distance between them less than or equal to the communication radius. Platform: |

Description: Wireless communications is, by any measure, the fastest growing segment of the communications industry. As
such, it has captured the attention of the media and the imagination of the public. Cellular systems have experienced
exponential growth over the last decade and there are currently around two billion users worldwide. Indeed,
cellular phones have become a critical business tool and part of everyday life in most developed countries, and
are rapidly supplanting antiquated wireline systems in many developing countries. In addition, wireless local area
networks currently supplement or replace wired networks in many homes, businesses, and campuses. Many new
applications, including wireless sensor networks, automated highways and factories, smart homes and appliances,
and remote telemedicine, are emerging from research ideas to concrete systems. Platform: |

Description: Next generation wireless network is envisioned as a convergence of different wireless access technologies
providing the user enhanced connection any where any time to improve the systems resource utilization. It
is likely that WLAN/HIPERLAN will become an important complementary technology to cellular
networks and typically used to provide hotspot coverage where there is a high density of users. In such
converged systems, co-existence of heterogeneous access technologies with largely different characteristics
like data rate for cellular network (2 Mbps), WLAN 802.11b (11 Mbps) and HIPERLAN (54 Mbps) results
in handoff asymmetry that differs from the traditional intra-network handoff (horizontal handoff). Platform: |

Description: In recent years a substantial increase in the development of broadband wireless access technologies
for evolving wireless Internet services and improved cellular systems has been observed [1].
Because of them, it is widely foreseen that in the future an enormous rise in traffic will be experienced
for mobile and personal communications systems [2]. This is due to both an increased
number of users and introduction of new high bit rate data services. This trend is observed for
second-generation systems, and it will most certainly continue for third-generation systems.
The rise in traffic will put a demand on both manufacturers and operators to provide sufficient
capacity in the networks [3]. This becomes amajor challenging problem for the service providers
to solve, since there exist certain negative factors in the radiation environment contributing to
the limit in capacity Platform: |

Description: Power control, broadly speaking, is the intelligent selection of transmitter power output in a communication system to achieve good performance within the system. The notion of good performance can depend on context and may include optimizing metrics such as link data rate, network capacity, geographic coverage and range, and life of the network and network devices. Power control algorithms are used in many contexts, including cellular networks, sensor networks, wireless LANs, and DSL modems.-Power control, broadly speaking, is the intelligent selection of transmitter power output in a communication system to achieve good performance within the system.

Description: To address the ever increasing high data rate and
connectivity requirements in the next generation 5G wireless
network, novel radio access technologies (RATs) are actively
explored to enhance the system spectral efficiency and connectivity. As a promising RAT for 5G cellular networks, nonorthogonal multiple access (NOMA) has attracted extensive
research attentions. Compared with orthogonal multiple access
(OMA) that has been widely applied in existing wireless communication systems, NOMA possesses the potential to further
improve system spectral efficiency and connectivity capability.
This paper develops analytical frameworks for NOMA downlink
and uplink multi-cell wireless systems to evaluate the system
outage probability and average achievable rate. In the downlink
NOMA system, two different NOMA group pairing schemes are
considered, based on which theoretical results on outage and
achievable data rates are derived. In the uplink NOMA, revised
back-off power control scheme is applied and outage probability
and per UE average achievable rate are derived. As wireless
networks turn into more and more densely deployed, inter-cell
interference has become a dominant capacity limiting factor but
has not been addressed in most of the existing NOMA studies.
In this paper a stochastic geometry approach is used to model a
dense wireless system that supports NOMA on both uplink and
downlink, based on which analytical results are derived either in
pseudo-closed forms or succinct closed forms and are further
validated by simulations. Numerical results demonstrate that
NOMA can bring considerable system-wide performance gain
compared to OMA on both uplink and downlink when properly
designed Platform: |
