What are the potential drawbacks of using cluster-based routing in large-scale sensor networks?4 answersCluster-based routing in large-scale sensor networks can face drawbacks such as uneven distribution of cluster heads, inappropriate selection of cluster heads, and energy inefficiency. These issues can lead to imbalanced energy consumption among nodes, reducing the overall network lifetime and performance. To address these challenges, researchers have proposed enhancements like the LEACH-OptCluster algorithm, which aims to maximize energy efficiency by balancing energy consumption across network nodes. Additionally, the NP-Hard nature of clustering in wireless sensor networks poses a challenge, prompting the use of optimization algorithms like particle swarm optimization (PSO) and firefly algorithms to improve energy-efficient routing and prolong network lifetime. Novel approaches based on neural networks have also been suggested to optimize power consumption and extend the operational lifespan of WSNs.
What are the challenges in implementing a wireless network?4 answersImplementing a wireless network poses several challenges. One major challenge is the issue of security and privacy. Wireless networks are more vulnerable to cyber attacks, making it crucial to address these concerns. Another challenge is the selection of suitable wireless protocols for different aircraft systems. It may be necessary to use multiple technologies as a single protocol may not be suitable for all systems. Additionally, the channel inside an aircraft can vary, and further measurements may be required to establish a generalized channel model. In the context of Industrial Wireless Sensor Networks (IWSNs), challenges include communication resource constraints, real-time rescheduling, and differential Quality of Service (QoS) requirements. Overall, the challenges in implementing a wireless network include security and privacy issues, protocol selection for different systems, channel modeling, and addressing specific requirements in various application domains.
What are the challenges of routing for UAV communications?4 answersRouting for UAV communications faces several challenges. Traditional flooding searching algorithms lead to high communication overheads, while greedy searching algorithms pose low routing efficiency. UAV networks have unique characteristics such as varying levels of dynamism, intermittent links, and fluid topology, which are not fully addressed by existing research in mobile ad-hoc networks (MANETs) and vehicular ad-hoc networks (VANETs). Moreover, UAVs in flying ad-hoc networks (FANETs) need to communicate with each other and ground stations, requiring the selection of effective paths for reliable and stable data transmission. Additionally, the dynamic network topology, high mobility, and resource constraints of UAVs make data forwarding challenging, necessitating the design of efficient routing protocols. These challenges highlight the need for routing algorithms that can adapt to the unique characteristics of UAV communications and ensure efficient and reliable data transmission.
What are the challenges and issues in routing in MANET?4 answersRouting in Mobile Ad hoc Networks (MANETs) faces several challenges and issues. The frequent mobility of network nodes and the dynamic topology make MANETs vulnerable to security threats, such as open nodes and disconnected links, leading to degraded network performance. The selection of Multipoint Relays (MPR) through flooding mechanism in the OLSR routing protocol has been widely used in MANETs, but there is still room for improvement in terms of routing and security. Machine learning techniques have been explored to enhance existing routing protocols or develop new ones, with a focus on real-time updating of route lists and node classification for optimization of routing processes. Additionally, the movement of nodes in MANETs makes routing demanding, and various performance measures, maximal performances, and attack analysis have been studied to address these challenges.
