The efficiency of inter-domain routing in large-scale mobile network environments is a critical issue, as traditional prefixed addresses may fail due to the dynamic topologies of mobile networks, where devices would be required to maintain massive routing tables. To address this issue, in this paper we leverage the principles of probabilistic data structures in the inter-domain routing scheme, and...
Aiming at satisfying in a cost-effective manner the forecast traffic growth that future mobile networks will need to support, traditional distributed Radio Access Networks (RANs) are evolving towards centralized architectures. Specifically, the Cloud-RAN (C-RAN) architecture has shown that can alleviate to some extent the ever increasing Total Cost of Ownership in mobile networks. The current trend...
To deal with the distributed estimation for mobile sensor networks with switching topologies, an algorithm of the weighted average consensus-based cubature Kalman filtering is proposed by combining the advantages of the cubature Kalman filtering in information form and consensus algorithm. On the basis of the predecessors research work, the sufficient condition is presented for ensuring the weighted...
Broadcast is a fundamental operation in Mobile Ad-Hoc Networks (MANETs). A large variety of broadcast algorithms have been proposed. They differ in the way message forwarding between nodes is controlled, and in the level of information about the topology that this control requires. Deployment scenarios for MANETs vary widely, in particular in terms of nodes density and mobility. The choice of an algorithm...
Multi-UAS (MAS) flocking requires multiple controllers with connected communication topologies. Real-time deployment of multi-agents is commonly associated with dynamic communication topologies, which has been considered as a challenging topic. This paper proposes a novel low- computation distributed connectivity control method to generate connected communication topologies and maintain the connectivity...
The Mobile Cloud Network is an emerging cost and capacity heterogeneous distributed cloud topological paradigm that aims to remedy the application performance constraints imposed by centralised cloud infrastructures. A centralised cloud infrastructure and the adjoining Telecom network will struggle to accommodate the exploding amount of traffic generated by forthcoming highly interactive applications...
Automatic Configuration Management (CM) parameter change assessment, the so-called Self-Organizing Network (SON) verification, is an important enabler for stable and high-quality modern mobile communication networks. However, it also presents a new set of challenges. While improving network stability and resolving unexpected conflicts caused by parallel configuration changes, SON verification can...
The tendency of any mobile technology is to automate as many of its processes. LTE (Long Term Evolution) introduces the concept of SON (Self-Organizing Network) that targets the automation of a large number of LTE processes. On the other hand, Peer to Peer (P2P) technology, even if it is used mainly in Internet and file sharing applications can bring significant improvements to LTE. This article discusses...
The mobile ad-hoc networks (MANETs) represent a broad area of study and market interest. They provide a wide set of applications in multiple domains. In that context, the functional and non-functional monitoring of these networks is crucial. For that purpose, monitoring techniques have been deeply studied in wired networks using gossip-based or hierarchical-based approaches. However, when applied...
As MANET is an infrastructure less, problems related to reduce Flooding by Propagating Neighborhood Information Algorithm (PNIA) is instant path transformation with reverence to transform in topology and blocking in the network. In this paper we have explained on PNIA with Grid Fisheye State Routing Protocol for MANET and implemented with various metrics in NS3 Simulator. Also the proposed work is...
Mobile ad hoc networks (MANETs) are continuously self-organizing, infrastructure-less consisting of collection of mobile nodes that communicate with each other without the use of centralized authority. MANETs are perfect for positions where a fixed structure is infeasible. Today's MANETs, suffer from network partitioning. This restriction makes MANETs in appropriate for applications such as crisis...
Mobile Ad hoc Networks (MANETs) are self-configuring, de-centralized and a kind of multi hop wireless packet networks, where the mobile gadgets (also referred to as nodes) communicate with each other on wireless links. Such networks find applications where a quick deployment or dynamic reconfiguration of network is required, or there is no pre-existing network infrastructure or wired network is available...
With the ubiquitous usage of mobile devices, most communications are now impacted by the users' mobility. Therefore, applications and services must be designed to cope with network dynamics produced by those mobility patterns. Software research and development would benefit from taking device mobility into account. However, implementing and testing software on real devices is costly and cumbersome...
In this paper, we propose topology based adaptive hybrid multicast routing (THMR) mechanism in mobile ad hoc networks. With the help of technique derived from Computational Intelligence (CI) discipline, Topology Change Rate (TCR) is predicted based on link behavior and node mobility for both proactive and reactive routing region in MANETs. We design a Reinforcement Learning (LR) based Q-Learning (QL)...
We propose the use of a graph-theoretic metric called Algebraic Connectivity (ALGC) computed on the egocentric network of an edge to quantify the extent of shared neighborhood between the end vertices of the edge/link in mobile sensor networks (MSNs). The chances for the egocentric network of an edge to stay connected increases with increase in the number of triangles involving the end vertices of...
Many MANET routing protocols do not perform well in dense scenarios with high network load. In these situations, we can observe a high level of route instability, which is often called "route flapping". In this paper we present the PRIME routing protocol, which uses a probabilistic multipath forwarding process to increase route stability in dense scenarios with high network load. We describe...
Monitoring techniques have been deeply studied in wired networks using gossip and hierarchical approaches. However, when applied to a MANET, several problematics arise. We present a hybrid distributed monitoring architecture for MANETs. We get inspired of gossip-based and hierarchical-based algorithms for query dissemination and data aggregation. We define gossip-based mechanisms that help our virtual...

The routers in CCN have the caching abilities and the caching strategies affect the system performance greatly. Each content in CCN is associated with a popularity, which is determined by the corresponding requested times. Popularity-aware caching scheme caches the...
