Topology-aware multicasting in phased mobile ad hoc networks for e-learning
This thesis presents an adaptive multicast routing protocol called a Topology-Aware Polymorphic Multicast Routing Protocol (TAPMRP) for use in Mobile Ad hoc NETworks (MANETs). TAPMRP is proposed to serve E-Learning classroom (ELC) environments, which are generally characterised by minimal topology …

WiFi ad-hoc message propagation over GPRS networks
Mobile ad hoc networks (MANETs) are networks that can be created spontaneously with no prior set up. Arbitrary nodes can form such networks by intercommunicating directly in a peer-to-peer fashion using wireless communication technologies, such as IEEE 802.11 (or WiFi). The number of WiFi-enabled …

Protecting Mobile Ad Hoc Networks from Spurious CTS Attacks 'Carrier Sensing based Deferral Mechanism'
… used to combat Hidden/Exposed node problems in Mobile Ad Hoc Networks (MANETs). The popular implementation of the RTS/CTS mechanism may lead to virtual blocking of the wireless medium. Problem arises if a malicious node randomly sends out a large number of spurious CTS frames in order to falsely …

On Reputation and Data-centric Misbehavior Detection Mechanisms for VANET
Vehicular ad hoc networks (VANET) is a class of ad hoc networks build to ensure the safety of traffic. This is important because accidents claim many lives. Trust and security remain a major concern in VANET since a simple mistake can have catastrophic consequence. A crucial point in VANET is how …

A Penalty-Based Approach to Handling Cluster Sizing in Mobile Ad Hoc Networks
<p>In Mobile Ad Hoc Networks (MANETs) nodes are allowed to move freely which causes instability in the network. To handle this, the nodes are grouped into clusters which make the topology of the network appear more stable. In proposed algorithms, the size of these clusters has been either ignored …

Collaboration Enforcement In Mobile Ad Hoc Networks
Mobile Ad hoc NETworks (MANETs) have attracted great research interest in recent years. Among many issues, lack of motivation for participating nodes to collaborate forms a major obstacle to the adoption of MANETs. Many contemporary collaboration enforcement techniques employ reputation mechanisms …

Simulating Internet of Things Mobile Ad-Hoc Networks with Distributed Ledger Technology: "Which DLT is Best?"
… We identify an under-studied niche of IoT Mobile Ad-hoc NETworks (MANETs) to best utilize DLTs, and challenge ourselves to put an entire cryptographically secure DLT on a \$46 Arduino MKR WAN 1310. To accomplish this we create an open-source simulator for IoT-MANETs with several …
