Resilient Framework for Next-Generation Heterogeneous Wireless Networks in Disaster Management

The growing occurrence and concentration of natural and artificial disasters necessitate the development of robust communication systems capable of maintaining reliable and efficient connectivity under adverse conditions. Heterogeneous wireless networks (HSNs) have emerged as a promising solution, offering the flexibility to integrate various wireless technologies and adapt to changing environments. However, the inherent complexity and dynamic nature of HSNs present significant challenges in ensuring resilience and reliability, particularly in disaster scenarios where network infrastructure may be severely compromised. This research investigates a Resilient Framework for Next Generation Heterogeneous Wireless Networks in Disaster Management, focusing on enhancing communication reliability and efficiency during critical scenarios. The study introduces Network Coding Enhanced COPE (NC-COPE), a novel algorithm integrating network coding principles into the COPE framework. Simulation analysis compares NC-COPE with existing algorithms: Optimized Link State Routing (OLSR), Coding-Aware Routing (CAR), and Dynamic Source Routing (DSR) using metrics such as Packet Delivery Ratio (PDR), Routing Overhead, and Resilience to Node Failures. NC-COPE demonstrates superior performance in maintaining high PDR, reducing routing overhead, and enhancing network resilience under node failures. The findings underscore NC-COPE's potential to mitigate communication challenges in disaster management scenarios, highlighting its role in future wireless network deployments.

I. Introduction

Next generation heterogeneous wireless networks represent a paradigm shift in wireless communication, characterized by the seamless incorporation of diverse wireless technologies such as WiFi, cellular networks, sensor networks, and satellite communications. These networks are designed to leverage the strengths of different technologies to provide ubiquitous connectivity, enhanced data rates, and improved quality of service. The heterogeneous nature of these networks allows for greater flexibility and adaptability, enabling efficient resource utilization and dynamic network management. Key features of next-gen HSNs include advanced routing protocols, adaptive resource allocation, and robust security mechanisms [17], all of which contribute to their ability to support various applications in various domains.
