Resilient routing for MANETs
Mobile ad hoc networks (MANETs) are the core technology that provides the US military with adaptable and reliable battlefield communications. These self-organising networks are ideal for rapidly changing scenarios that require connectivity even under hostile conditions. The excitement and promise …

Mobility Metrics for Routing in MANETs
A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without the need for base stations or any other pre–existing network infrastructure. In a peer-to-peer fashion, mobile nodes can communicate with each other by using wireless multihop communication. …

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without the need for base stations or any other pre–existing network infrastructure. In a peer-to-peer fashion, mobile nodes can communicate with each other by using wireless multihop communication. …

Denial of Service Attacks in MANETs
… protocols designed specifically for use in MANETs - AODV and OLSR. We compare the performances of these two protocols during simulations of an IoBT scenario, and also analytical compare how they respond to two specific DoS attacks - black hole and flooding.

Modified location aided routing protocol for UWB manets
… has become a promising candidate to supportMANETs due to the large Band Width available and the high data rates achievable. Routingprotocols running within MANETs provide mobile hosts (or nodes) the ability tocommunicate with each other; and the design of routing protocols has encouraged …

Virtual closed networks: optimised security for autonomous MANETs
… undertake a given task. Mobile ad hoc networks (MANETs) provide the foundation for such communication, providing a means by which nodes may communicate with other members of the network, even if they are not in range. Issues arise when considering the security of MANET communication, due to the …

A DHT-Based Routing Solution for Hierarchical MANETs
… solution for the backbone of hierarchical MANETs. Our solution leverages the storage and retrieval mechanisms of a DHT to make routing information available in a decentralized fashion, while supporting different forms of node and network mobility scenarios effectively. We do so by splitting …

A layered security approach for cooperation enforcement in MANETs
In fully self-organized MANETs, nodes are naturally reluctant to spend their precious resources forwarding other nodes' packets and are therefore liable to exhibit selfish or sometimes malicious behaviour. This selfishness could potentially lead to network partitioning and network performance …

Load distribution and energy awareness in manets using multipath routing
Wireless ad-hoc networks are characterised by lack of infrastructure and frequent topological changes. Traditional routing protocols seek only single paths to the desired destinations, while multipath routing obtains multiple paths for only marginal additional overhead. This work argues that …

Probabilistic route discovery for Wireless Mobile Ad Hoc Networks (MANETs)
Mobile wireless ad hoc networks (MANETs) have become of increasing interest in view of their promise to extend connectivity beyond traditional fixed infrastructure networks. In MANETs, the task of routing is distributed among network nodes which act as both end points and routers in a wireless …

OLSR-based network discovery in situational awareness system for tactical MANETs
In this thesis, we propose a high level design for connectivity visualization of OLSRbased MANET topology based on local topology databases available in an OLSR node. Two different scenarios are considered: a central (full view) topology from a command and control location, or a nodal (partial) …

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 …

Evolutionary Computation Techniques for Intrusion Detection in Mobile Ad Hoc Networks
Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. By providing communications in the absence of a fixed infrastructure MANETs are an attractive technology for many applications. However, this flexibility introduces new security threats. Furthermore the traditional …

Proactive mobile wireless networks : an infrastructureless wireless network architecture for delay-sensitive applications
… networks called mobile ad hoc wireless networks (MANETs). In addition to autonomous network formation, wireless devices in MANETs have routing capabilities and help one another to forward information in a multihop fashion. The applications envisioned for MANETs include communication during …

Trust Management for P2P application in Delay Tolerant Mobile Ad-hoc Networks. An Investigation into the development of a Trust Management Framework for Peer to Peer File Sharing Applications in Delay Tolerant Disconnected Mobile Ad-hoc Networks.
… traditional security schemes proposed for MANETs cannot be applied. This thesis reports trust management schemes for peer to peer (P2P) application in delay tolerant disconnected MANETs. Properties of a profile based file sharing application are analyzed and a framework for structured P2P …

Mobile Ad-hoc Network Routing Protocols: Methodologies and Applications
… infrastructure to provide network connectivity. MANETs have applications in rapidly deployed and dynamic military and civilian systems. The network topology in a MANET usually changes with time. Therefore, there are new challenges for routing protocols in MANETs since traditional routing …

Performance evaluation of routing metrics for wireless mesh networks
… were designed with mobile ad hoc networks (MANETs) in mind. These routing metrics might be useful in wireless mesh networks (WMNs) but the fact that WMNs and MANETs are two different types of wireless networks with different features might not allow optimal performance of some or all …
