Our approach oﬀers several capabilities, including seamlessly interconnecting heterogeneous MANETs, reducing routing decision loads of gateway routers, and managing end-devices at the network edge from the Network Operation Center (NOC) with our SDN Proxy Protocol. To assess the feasibility of our proposed approach, we setup an emulation environment, and implement our designed system via the Constrained Application Protocol (CoAP), additionally integrating OLSRv2, OSPF-MDR, Babel, and others. Based on a set of designed test scenarios, we then carry out an extensive performance evaluation of our approach. Our experimental results show signiﬁcant network performance improvements at the gateway routers. The SDN Proxy Protocol also outperforms the traditional CoAP-to-CoAP communication when network instability exists.

sessions, we propose a Priority Based Routing and link Scheduling (PBRS) scheme for multi-hop cognitive radio networks. The objective is to minimize disruption to communication sessions due to channel switching as well as to minimize network resource consumption for multimedia applications based on a prioritized routing
and resource allocation scheme. PBRS includes a priority based optimization formulation and an efficient
algorithm to solve the problem. The main idea is to allocate the available resource to different types of services with their Quality of Experience (QoE) expectation as well as maintain a priority service queue. Services with higher priority such video conference with cognitive radio expects a lower latency during the communication, whereas services with lower priority such as file transferring could tolerate more interruptions. Based on the different QoE requirements of services, PBRS will decide whether or not to change the routing and link scheduling. If a session has a higher priority than the others, PBRS will maintain its routes, channels, and links to the next timeslot as long as the total white space resource is enough to support all sessions. This eliminates unnecessary channel switching due to rescheduling. Simulation results demonstrate that PBRS effectively reduces channel switching and hence reduce disruption to communication sessions.

In this paper, we systematically analyze CTO-based schemes and develop new schemes to improve network performance by reconnecting disconnected devices. First, we conduct an investigation of CTO-based schemes to understand their limitations. Then, we propose two schemes, called the Power Control-based scheme and Femto Relaybased scheme, to overcome this limitation in LTE networks, in which CTO-based schemes are implemented. Via intensive performance evaluation using NS3, we validate the effectiveness of our proposed schemes towards addressing the limitations of CTO-based schemes. Our results demonstrate an improvement in LTEnetwork performance above both the unoptimized and CTO-based schemes with respect to throughput, delay, delay standard deviation (DSD), etc.

mobile ad hoc network. They propose that data concerning vital signs of tactical radio operators be used as context
information for spectrum management. If the operator’s inability to operate and protect the tactical radio is identified,
actions (remote control of radio) are taken with the aim to release spectrum resources which used by the radio.
Additionally, in this case remote control of radio allows switch the radio to modes used by search and rescue teams and
lock the radio for unauthorized person.

OBJECTIVES: The primary objective of this study was use vital signs of tactical radio operator’s as context information
for dynamic spectrum management within MANET.

METHODS: Tests for correct detection of vital signs were carried out for data generated on a Hal S3201 adult patient
simulator. Hypotheses about radio operator's vital signs were verified by means of a belief function defined in DempsterShafer theory.

RESULTS: Loss vital signs by the operator allows to remote turn off his/her tactical radio while allocating more resources
to other network users, which allow increasing data throughput.

CONCLUSION: Monitoring vital signs of a tactical radio operator enables detecting combat readiness loss which results
in inability to protect communications and can be used in spectrum management mechanisms.

In this regard, this paper provides an analysis of a Reinforcement Learning (RL)-based RAN slicing strategy for a heterogeneous network with two generic services of 5G, namely enhanced mobile broadband (eMBB) and vehicle-to-everything (V2X). In particular, this paper investigates the RAN slicing by evaluating the proposed scheme under different algorithm configurations (i.e., number of actions of RL) and parameters in order to analyze the performance in terms of metrics such as RL convergence time and to demonstrate the capability of the algorithm to perform an efficient allocation of resources among slices. In addition, this study compares the results obtained by the proposed solution to those obtained with a Proportional Scheme.

lower frequencies, which calls for spectrum sharing for local networks. Spectrum sensing could complement
traditional database approach for spectrum sharing in these areas. This paper studies a windowing based
(WIBA) blind spectrum sensing method and compares its performance to a localization algorithm based on
double-thresholding (LAD). Both methods are based on energy detection and can be used in any band for
detecting rather narrowband signals. Probabilities of detection and false alarm, relative mean square error,
number of detected signals and detection distances were evaluated in multipath, multi-signal and rural area
channel conditions. The simulation results show tha the WIBA method is suitable for 5G remote areas, due
to its good detection performance in low signal-to-noise ratios (SNR) with low complexity. Results also show
importance of the detection window selection.
