This paper is a survey of new and improved recent position based routing methods in Mobile Ad-hoc Networks. The referenced materials agree on the main challenge in creating energy efficient mobile ad-hoc networks. The quest is to realize a simple, yet efficient means of routing and managing the Mobile Ad-hoc Network communications with existing technology. Although many protocols have been proposed,...
Wireless Sensor Networks (WSNs) comprise of groups of tiny sensor nodes that are deployed for collaborative missions such as environmental monitoring, target tracking and surveillance. Due to the miniature size of the nodes, they are typically deployed in large numbers and communicate via multiple hops through a wireless shared communication channel. The successful implementation of such networks...
Mobile ad hoc networks (MANETs) are multi-hop wireless networks of autonomous mobile nodes without any fixed infrastructure. In MANETs, it is difficult to detect malicious nodes because the network topology constantly changes due to node mobility. A malicious node can easily inject false routes into the network. A traditional method to detect such malicious nodes is to establish a base profile of...
Cognitive radio ad hoc networks (CRAHNs) are the ad hoc networks equipped with the intrinsic capabilities of the cognitive radio. As CRAHNs devices are mainly powered by battery, efficient consumption of energy is a key issue in CRAHNs. This paper focuses on energy-efficient routing in CRAHNs. It first compares CRAHNs with mobile ad hoc networks (MANETs), surveys the existing energy-efficient routing...
Specific properties of MANETs results in basic differences between wired networks and wireless networks in security solutions. In recent years, trust models have established themselves as a main approach for security and performance improvement of sections of MANETs. Recent researches have used trust models for problems like routing, admission control and information sharing in MANETs. In spite of...
Adhoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of existing network infrastructure or centralized administration. Each node acts as a router by itself and forwards all the packets which it receives. There is a frequent link failure in adhoc Networks, which causes packet to be lost or packets doubt to reach destination. In this scenario...
Wireless Mesh Networks (WMNs) have emerged as an important technology in building next generation fixed wireless broadband networks that provide low cost Internet access for fixed and mobile users. An orthogonal evolution in computer networking has been the rise of Peer-to-Peer (P2P) applications such as P2P file sharing. It is of interest to enable effective P2P file sharing in this type of networks...
To support seamless communications for roaming users over heterogeneous wireless networks, mobile ad-hoc networks (MANETs) are receiving a special interest in the research community due to its infrastructure-less nature. MANETs can help to achieve a seamless service for users roaming over areas with no coverage from other wireless networks. As a result, MANETs are a key access network component of...
To cater for different conditions of QoS application, this paper proposes an adaptive cross-layer QoS model for mobile Ad Hoc networks according to their characteristics. Based on the traditional TCP/IP protocol stack, the cross-layer information exchange module and the adaptive decision-making module are added. The cross-layer information exchange module breaks the restriction of the original layer...
In recent years, with advance in wireless communication technology, sensing technology, micro-electronics technology and embedded system, wireless sensor network (WSN) can be used for various application areas, such as home health care, military and industry. The localization service which provides the location information of mobile user is one of important service provided by WSN, because many applications...
Wireless mobile ad hoc networks can be used as a means to ease and support life in an ordinary house. As future home appliances will have many useful built-in functions, a communication network that allows a user to access these built-in functions and to control the appliances is highly desirable. This paper proposes a routing algorithm for mobility in a description-based clustered ad-hoc network...
In this paper, we introduce the stable path topology control problem for link-state routing in mobile multi-hop networks. We formulate the topology control problem of selective link-state broadcast as a graph pruning problem with restricted local neighborhood information. We develop a multi-agent optimization framework where the decision policies of each agent are restricted to local policies on incident...
Security in mobile ad hoc networks (MANETs) is an active research topic. Bulks of prior work focused on key management and secure routing without addressing an important pre-requisite: network access control, the problem of how securely extend the network. In this paper, we present INAC, an identity-based network access control scheme for MANETs. In INAC, each node in the network must have an identity-based...
Mobile Ad-hoc NETwork (MANET) is a collection of wireless mobile nodes without any fixed base-station infrastructure and centralized management. Topological changes in MANETs render routing paths unusable. The multipath routing addresses this problem by providing more than one route to a destination node. Shared links and nodes between paths present common failure points which can disable many or...
Topological changes in Mobile Ad-hoc NETwork (MANET) render routing paths unusable. Using multiple redundant paths between the source and the destination is a technique which reduces the affect of this problem. Shared links and nodes between paths present common failure points which can disable many or all of the paths. Disjoint path set requires the multiple paths to be link- or node-disjoint. However,...
A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes an analytical analysis of energy parameters, their usage and their evaluation in ad hoc networks. The scheme is incorporated with the AODV and...
The future wireless mobile devices considered in this paper incorporate three key features: (1) Wireless Wide Area Network (WWAN) radios, (2) short-range high-data-rate Wireless Personal Area Network (WPAN) radios, and (3) large (>;100GB) amounts of on-board cache. Approaches for finding and exploiting knowledge of Social Networks to decrease spectrum congestion and network latency in networks...
To restore the performance of the system due to the failure of a BS, we propose a hybrid vehicular communication system which introduces a novel double cluster head (DCH) routing scheme. Using vehicular traces from loop Ids on the M4 motorway in the UK, the performance of the system is evaluated and compared with the single cluster head (SCH) routing scheme under different configurations. Even though,...
Mobile Ad hoc networks (MANETs) are self organizing and self-configuring multi-hop wireless networks. They are able to re-configure themselves when they are affected by node mobility. In the field communication nodes are very sensitive to node mobility and it can be interrupted if the topology changes. If the mobility prediction is used to predict the future position of a node, the resources reservation...
Simulation is a fundamental means for evaluating mobile applications based on ad-hoc networks. This has led to the design of a large number of mobility models for simulating realistic user movement under physical constraints (obstacles, acceleration, inertia etc.). In recent years, the new breed of social mobility models (SMMs) has risen. These SMMs model the social aspects of human mobility, i.e...
