topology control in next-generation wireless networks has recently attracted the interest of several researchers. The network performance is significantly affected by the topology. Therefore, creating an optimal topology is essential, particularly in fifth-generation (5G) networks, where latency, throughput, energy efficiency, and other performance metrics are highly stringent. In this study, we investigated topology control algorithms in 5G-based mobile ad-hoc networks (MANET). A novel algorithm, namely Topological control by Flexibly Adjusting the Coverage Radius (TFACR) was proposed to improve network performance. The main idea of the TFACR algorithm is to adjust the communication range flexibly to obtain the desired degree of nodes. The degree constraint of the neighboring nodes is considered each time a node adjusts the communication area to ensure node degree balancing throughout the network topology. The TFACR algorithm is implemented in the OMNET++ and INET frameworks using the Reinforcement Learning-based routing protocol (RLRP), Ad-hoc On-demand Distance Vector (AODV) and Destination Sequenced Distance Vector (DSDV) routing protocols to evaluate its performance. The simulation results proved that the proposed algorithm outperformed well-known topology control algorithms in terms of the average node degree, quality of transmission, and energy consumption. This is suitable for 5G-based MANET.

As the foundation of routing, topology control should minimize the interference among nodes, and increase the network capacity. With the development of mobile ad hoc networks (MANETs), there is a growing requirement of quality of service (QoS) in terms of delay. In order to meet the delay requirement, it is important to consider topology control in delay constrained environment, which is contradictory to the objective of minimizing interference. In this paper, we focus on the delay-constrained topology control problem, and take into account delay and interference jointly. We propose a cross-layer distributed algorithm called interference-based topology control algorithm for delay-constrained (ITCD) MANETs with considering both the interference constraint and the delay constraint, which is different from the previous work. The transmission delay, contention delay and the queuing delay are taken into account in the proposed algorithm. Moreover, the impact of node mobility on the interference-based topology control algorithm is investigated and the unstable links are removed from the topology. The simulation results show that ITCD can reduce the delay and improve the performance effectively in delay-constrained mobile ad hoc networks.

In recent years, unmanned aerial vehicles (UAVs) have attracted increased attention from academic and in-dustrial research communities, owing to their wide range of potential applications in military and civilian do-mains. A collaborative group of UAVs operating in an ad hoc manner known as a flying ad hoc network (FANET) can accomplish complex tasks more efficiently. However, owing to the high mobility of UAVs, such applications remain limited by a few key challenges, including dynamic time-varying topologies, energy constraints, frequent link breakages, inter-UAV collisions, and external obstacle avoidance. A proper topology control algorithm (TCA) for UAV swarms with reasonable overhead helps to optimize both mission and communication performance in FANET. Thus, TCA provides wider coverage ensuring the quality of service in aerial connectivity. Additionally, it supports the efficient energy management, better target exploration, improved formation stability while ensuring inter-UAV collision avoidance, external obstacle avoidance, lower interference, and the enhanced autonomy of UAV swarms. In this article, we present a comprehensive survey of available TCAs for FANET, and provide a novel taxonomy of TCAs based on the FANET topology architectures and underlying mathematical models. Through an in-depth assessment of recent innovative research articles and their comparative studies, we aim to provide novel insights into the latest technologies for autonomous cooperative coordination. The key open research issues and their respective solutions are addressed as future research directions.

Efficient topology control of wireless sensor networks is very important to reduce the energy consumption and prolong the system lifetime. In this paper. a novel topology control algorithm based on the polymorphic ant colony (PAC) working with different control rules is proposed and evaluated. The queen ant dynamically remodels the networks clustering structure based its cost function. The worker ants and the scout ants control their communication model based on their optimal expectation and real-time pheromone. With the mechanism, the energy consumption level for the nodes composed of worker ants and scout ants can be reduced. The simulation results demonstrate that the proposed algorithm can effectively reduce the energy consumption and prolong the system lifetime.

topology control for minimizing interference with delay constraints in an ad hoc network

Most of the existing work on topology control is to minimize the interference or delay separately. However, minimizing the interference and reducing the delay are two conflicting goals;therefore, considering a trade-off between them is necessary. In this paper, our goal is to minimize the interference while guaranteeing the end-to-end delay under a constraint. We take into account three optimization objectives, including the maximum interference, average interference and average path interference. We propose a centralized algorithm with a greedy strategy that can minimize the maximum interference while satisfying the delay constraint. A distributed algorithm(LDMST) is proposed to minimize the average interference. In LDMST, each node builds a delay-constrained minimum spanning tree (DMST). To minimize the path interference, a localized delay-constrained Bellman-Ford (LDBF) algorithm is proposed. LDBF employs an improved Bellman-Ford algorithm to find the optimal path, which has the minimum interference and satisfies the delay constraint. The final topology is composed of these optimal paths. The simulation results illustrate that the proposed topology control algorithms exhibit good performance in terms of the interference objectives and can also guarantee the end-to-end delay under the constraint.

KMCD-IME (Keeping the Maximum Communication Distance and Initial Mutual Exclusion among Router Nodes) topology control algorithm for Effective Routing in ZigBee Networks

In a ZigBee network, a finite address space is allocated to every potential parent device and a device may disallow a join request once this address space is exhausted. When a new node (child) requests to a coordinator (parent) to join a ZigBee network, the coordinator checks its address space. If it has sufficient address space, the coordinator accepts the new node as its child in the ZigBee network. If the new node has router capability (JoinAsRouter), it becomes a router in the ZigBee network. However, this association procedure makes ZigBee networks inefficient for routing, because the coordinator checks only the maximum and current numbers of child nodes. In the worst case, the network will be arranged so that the router nodes are crowded in the network. Therefore, we propose the KMCD-IME (Keeping the Maximum Communication Distance and Initial Mutual Exclusion among router nodes) algorithm with two additional conditions when a new node joins the ZigBee network. The first condition maintains the maximum communication distance between the new node and the would-be parent node. The second condition is the Initial Mutual Exclusion among router nodes. The router nodes are evenly spread across the network by KMCD-IME and an effective routing topology is formed. Therefore, the KMCD-IME algorithm extends the lifetime of the ZigBee network.

Power control algorithms are an important consideration in mobile ad hoc networks since they can improve network capacity and lifetime. Existing power control approaches in ad hoc network basically use deterministic or probabilistic techniques to build network topology that satisfy certain criteria (cost metrics), such as preserving network connectivity, minimizing interference or securing QoS constraints. In this paper, we will provide a survey of the various approaches to deal with power control management in mobile ad-hoc wireless networks. We will classify these approaches into five main approaches: (a) Node-Degree Constrained Approach, (b) Location Information Based Approach, (c) Graph Theory Approach, (d) Game Theory Approach and (e) Multi-Parameter Optimization Approach. We will also focus on an adaptive distributed power management (DISPOW) algorithm as an example of the multi-parameter optimization approach which manages the transmit power of nodes in a wireless ad hoc network to preserve network connectivity and cooperatively reduce interference. We will show that the algorithm in a distributed manner builds a unique stable network topology tailored to its surrounding node density and propagation environment over random topologies in a dynamic mobile wireless channel.

Single-radio mesh routers operating on a single channel suffer from low throughput due to collisions. Equipping mesh routers with multiple radios operating on non-overlapping channels can significantly improve the throughput. However, the assignment of channels to radios in a multi-radio mesh network is a challenging task. In this paper, we propose a channel assignment algorithm, TICA (topology-controlled Interference-aware Channel-assignment algorithm), which significantly improves network throughput by minimizing interference within the mesh network using a novel approach of controlling the network topology based on power control before intelligently assigning the channels to the multi-radio mesh routers, as well as guaranteeing network connectivity.
