A Mobile Adhoc Network (MANET) is featured by multi hop wireless connectivity with topology change due to highly mobile stations with autonomous configuration ability. Therefore, it is very challenging to develop vibrant and resourceful routing Protocol for MANET which also performs excellent routig with security feasibility. This paper presents a detailed study and analysis of various routing issues...
Security is the main issue of the mobile ad-hoc network, because of mobile nodes behavior. The topology of MANET changes frequently due to nodes mobility, by this property newly node easily enters or exit from a particular area. In this paper, we go through the study about mobile ad-hoc network and role of soft computing in this network. In our proposed work we apply Dempster Shafer theory for calculating...
Mobile networks in the military tactical domain, include a range of radio networks with very diverse characteristics and which may be employed differently from operation to operation. When interconnecting networks with dissimilar characteristics (e.g. capacity, range, mobility) a difficult trade-off is to fully utilize the diverse network characteristics while minimizing the cost. To support the ever...
In the past, many researchers depend highly on various real life environmental short coverage area networks to analyze the performance of various routing algorithms. Recent ever-increasing interest in vehicular ad hoc network communication (VAC) necessitates vehicular movement performance study via different mobility pattern simulation. Unlike many other works, we present a study on the performance...
Merging IP routing and mobile communication poses many challenges especially for a dynamic, heterogeneous networking environment such as a Naval Task Force. In this paper, we present an effort to design, develop, test and demonstrate an interoperable coalition interface for a Naval Task Force for the four-nation Coalition Networks for Secure Information Sharing (CoNSIS) project. A field experimentation...
Delay Tolerant Networks formed by mobile devices users carry in their everyday life are starting to be an interesting alternative for message transmissions between users. However, the reliability of the DTNs is an important research topic, one of the main causes of poor DTN reliability being the selfishness of the network nodes. In this paper, we evaluate the impact of selfishness on the efficiency...
Mobile Ad hoc Networks (MANETs) always bring challenges to the designers in terms of its security deployment due to its dynamic and infrastructure less nature. In the past few years different researchers have proposed different solutions for providing security to MANETs. In most of the cases however, the solution is targeting a particular attack or multiple attacks but fails to find the root cause...
Tactical networks consisting of mobile wireless nodes with various platforms have been developed with Mobile Ad-hoc Network (MANET). The provision of Quality of Service (QoS) is still ongoing problem to be solved in MANET due to its lack of resources and harsh propagation environments. In these environments, link failure can be occurred because of frequent mobility of wireless nodes. During the route...
Future spatial network will be a large-scale wireless communication network with dynamic topology, where current routing protocols have been found unsuitable for use. Although CCSDS designed SCPS-NP protocol for spatial network several years ago, they could not definitely offer a point-to-point routing algorithm. To resolve the problem of SCPS-NP routing, this paper analyzed general networking specifications...
The vehicular wireless ad hoc network (VANET), a specialized wireless sensor network, is booming to provide safety and comfort for passengers. Special features of VANET, such as high mobility nodes and large scale node population, make the Quality of Service (QoS) task extremely challenging. To provide Quality of Service (QoS) to traffic safety and entertainment applications in VANET, we propose a...

In this paper, Time Transitional AHP based on emergent policy in Cognitive Wireless Network is proposed. The proposal system is expected with cognitive wireless network consisted with multi wireless link and route, and the link and route selection...
The challenges of mobile ad hoc network are to maintain quality of services and performance. Many routing protocols like AODV discover routes whenever required by the source node and the benefit in doing so is that no prior knowledge of the topology is required. The AODV routing protocol is commonly and effectively used for mobile, ad-hoc nodes. So far, many maintenance strategies have been proposed...

Ad-hoc mobile networks consist of many mobile nodes which communicate by wireless connections without any fixed infrastructure. Our present article, we will compare two types of routing: the reactive algorithm (AODV) and the proactive algorithm (OLSR). Through our simulation carried out under NS2 (Network Simulator 2), we will show a classification of the various algorithms of routing studied according...
The objective of the work is to propose a Quality of Service (QoS) aware heterogeneous networking model for emergency management system using network virtualization. An emergency management information system is made up of heterogeneous communication and computing networks to address the crisis situation and adopt the network according to the service parameters. To meet the unpredictable demands and...
MANET is an autonomous system of mobile wireless nodes connected dynamically without any preexisting infrastructure. Since the nodes are mobile, the network topology changes rapidly and unpredictably over time. The QoS routing has challenging problems due to the network's dynamic topology and limited resources. If only one single constraint condition is considered when making routing decision, QoS...
A new Virtual Base Station (VBS) election technique is proposed by this paper to help in QoS provisioning in the infrastructure-less Mobile Ad-hoc Networks referred to as MANET. This VBS election technique is based on the mobile node's Signal-to-Noise Ratio (SNR) and has been applied on the MANET's hybrid routing protocol: The Zone-based Routing Protocol. The developed routing protocol will be referred...
With the increasing development of real-time and multimedia applications, there is a need to provide bandwidth and delay guarantees. Existing QoS ad hoc network routing protocols select path guaranteeing delay and/or bandwidth. However, they don't consider throughput optimization, which results in a low number of admitted real-time and multimedia flows. In this paper, we propose a cross-layer TDMA-based...
Wireless ad hoc networks are a collection of mobile nodes spreading over a defined geographical area, enabling realtime collaborative applications such as push-to-talk and VoIP.
