The nature of wireless ad hoc network is such that communication between the nodes is extremely volatile, resultantly the quality of the wireless links is heavily unstable. Implementation of algorithms with enormous processing power and memory capacity for small and restricted resource-constrained wireless nodes is an inspiring task. Performance and behaviour estimation and comparison of wireless ad hoc network protocols, simulations are upright solution between cost and complexity, on the one side, and accuracy of the results, on the other side. Such simulation tools should allow researchers to verify new ideas and compare the proposed solutions in a virtual environment helping to avoid unnecessary, time-consuming or expensive hardware implementations. Difficulty arises in selection of wireless ad hoc network simulator for specific objective, features and usability due to the prensence of lots of simulators. Reusability, availability, performance, scalability, support for rich-semantics, scripting languages and graphical support are the main requirments for best framework of the wireless ad hoc network simulator. Within the study, we have described desirable and valuable missing features of the simulators, demarcation of their strength and weaknesses. Lot of effort is required for installation, habituation, implementation and visualization of wireless ad hoc network simulator. A lot of researchers and Scholars can seek help from this paper to identify the suitability of simulator for their study.
The malfunctioning of critical infrastructure causes high-quality deterioration, financial effect and loss of life in a town in the present scenario. It is essential to check the cost-effectiveness and reliability of the quality of critical infrastructures in the pandemic situation. Sensitive monitoring of an infrastructure is costly but necessary, in which fault identification and corrective action are needed at service levels to avoid cascading failures with minimal communication latency. With enhanced expense, resource, and process performance, the growing population in smart cities demanded a high living standard, rigorously straining energy, city services, and infrastructure. Intelligent houses, intelligent transport and smart buildings linked with intelligent networks are three pillars of the smart city initiative. In this paper, an improved framework for enhanced Quality of Service with higher performance in a 5G network is presented. A detailed description of reconfigurable intelligent Smart networks and reconfiguration analysis at various layers are also discussed. SDN and NFV, with the help of an intelligent SDN controller, provide the context for managing a multi-objective heterogeneous network. For self-optimization and self-healing, multiple clustering heuristics are useful for managing these networks at the various locations of smart projects.
Abstract-One of the important aspects of MANET is the restraint of quantity of available energy in the network nodes that is the most critical factor in the operation of these networks. The tremendous amount of energy using the mobile nodes in wireless communication medium makes Energy Efficiency a fundamental requirement for mobile ad hoc networks. The cluster-based routing protocols are investigated in several research studies which encourage more well-organized usage of resources in controlling large dynamic networks. Clustering can be done for different purposes, such as, routing efficiency, transmission management, backbone management etc. Less flooding, distributed operation, locally repairing of broken routes and shorter sub-optimal routes are the main features of the Clustering protocol. In this paper, we present quantifiable analysis of energy efficient cluster-based routing protocol for uninterrupted stream queries.
