Challenges, Attacks, and Countermeasures for Security in MANETs-IoT

The integration of Mobile Ad hoc Networks and the Internet of Things offers innovative applications but also presents significant security challenges. This paper explores these challenges, considering the decentralized nature of both MANETs and IoT. Security vulnerabilities, including unauthorized access and malicious attacks, emerge due to factors like node mobility and resource constraints. Existing security mechanisms are examined and found insufficient for this combined environment. The primary security issues are confidentially, integrity, availability, blackhole, wormhole, grayhole, rushing, flooding, attacks, authentication, intrusion detection, and trust management tailored to MANET-IoT systems. The urgent need for comprehensive security strategies to ensure safe operation of this ecosystem is emphasized.
