A Mobility-Based Routing Protocol for CR Enabled Mobile Ad Hoc Networks

Abstract

With the fast development of hardware and chipset functionality and capability, smart devices equipped with advanced technologies, such as Cognitive Radio (CR) will offer promising opportunities for mobile network. The authors in this work design a mobility based routing protocol (CRMBR) which operates in CR enabled Mobile Ad hoc Networks (MANETs). The adopted cross layer structure transfers the cognitive sensing data, such as channel quality and available bandwidth, from Physical layer up to MAC/Network layers periodically. Network layer uses such information for executing route selection algorithm while MAC layer runs the sub-channel scheduling algorithm based on CR data before each transmission. CRMBR further employs an advanced acknowledgment scheme in MAC layer for sub-channel selection to reduce the control overhead while forwarding data in MANETs. The performance of CRMBR is investigated via simulations on OpNET platform and the results confirm its favorable operation within CR MANET environments compared to two classic routing protocols in Ad hot networks: AODV and DSR.

Secure Routing for MANET Connected Internet of Things Systems

“…Crucially however, security features for CRMBR are neither critically analyzed nor evaluated. [21] IV. THREATS AND VULNERABILITIES TO ROUTING IN MANETS Security threats against routing in MANETs are classified into either passive or active attacks [22].…”

Encryption Technique to Optimize Information Leakage in Multi Cloud Storage Services

“…The authors in [32] proposed a steering instrument dependent on portability which worked in Cognitive Radio empowered Mobile Ad hoc Networks (MANETs). This empowered the exchange of the subjective data, for example, accessible transmission capacity from the physical-layer to the MAC and system layers and the divert quality in an intermittent way by presenting a cross-layered substructure.…”
