A Framework for Integrated Routing, Scheduling and Traffic Management (FIRST) in Ad Hoc Networks is introduced. Unicast and multicast routes are established in coordination with the scheduling of transmissions and bandwidth reservations in a way that bandwidth and delay guarantees can be enforced on a per-hop and end-to-end basis. Results from detailed simulation experiments show that, compared to...
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...
The inherent uncertainty in wireless mobile ad hoc networks (MANET), due to nodal mobility, unstable links, and limited resources, frequently renders routing paths unusable. Due to the unpredictable movement of mobile nodes, the network topology of a mobile ad hoc network changes frequently. It will directly cause the routes to be broken and greatly degrade the network performance. However, selecting...
In multihop networks such as mobile ad hoc networks selfish or misbehaving nodes can degrade network performance. Reputation based models have been developed to enforce cooperation and to discourage node misbehaviour. These schemes detect and isolate selfish nodes and maintain network throughput by enabling nodes to construct paths that only include good nodes. In order to punish selfish nodes and...
Geocasting is a routing method for ad hoc wireless networks that uses geographic information to multicast to nodes within the geocast region. The multicast members cannot receive multicast data continuously when they move outside the geocast region. Therefore, a geocast-based multicast method for continuous information delivery in MANET environments was developed. The method combines geocasting and...
Link duration is the time interval during which two nodes are within transmission range of each other. In this paper, the link duration of the random waypoint (RWP) mobility model is derived and the result indicate that it is determined by the speed as well as incident angle of the speeds. By estimating the link duration in route selection for AODV, the energy, delay and packet delivery ratio metrics...
Although establishing stable routes for routing can improve the performance of mobile an hoc networks (MANETs), the improvement will be weakened to a degree for the stability of route is sensitive to the motion of node. In this paper, based on a basic stability-oriented routing scheme, named FORP, we involved two mobility-adaptive mechanisms in it. One mechanism is the real-time update of stability...
In this paper, we propose an Entropy-based Stability QoS Routing with Priority scheduler in MANET using fuzzy controllers (ESQR). The main idea of ESQR algorithm is to construct the new metric-entropy and select the stability path with the help of entropy metric to reduce the number of route reconstruction so as to provide QoS guarantee in the ad hoc network. Controllable elements in the different...
IEEE 802.15.4 is the emerging next generation wireless standard designed for low-rate wireless personal area networks (LR-WPAN), which suit wireless sensor networks applications. It attempts to provide a low cost, low power and short range wireless networking. The QoS is more challenging in heterogeneous wireless sensors networks, where a diverse mixture of sensors for monitoring temperature, pressure,...
The emergence of multimedia applications demands multicasting in MANETs. For such applications QoS provisioning is a complex and challenging issue. This paper proposes a QoS aware multicast routing scheme uses a set of static and mobile agents and ensures QoS guarantees in terms of bandwidth reservation, delay constraint, delay-jitter constraint and packet loss to multicast session. Here the mobile...
To truly realize potential of MANET, multimedia services must be provisioned with a minimum level of QoS. To meet the QoS requirement of such services, many attributes need to be considered. To keep the routing process lightweight, standard QoS aware routing protocol in MANET works with one or two such parameters. In this paper, we have proposed an on-demand source routing protocol for MANET that...
In this last two years an increasing number of scientists has devoted his attention to Vehicular Ad hoc NETworks (VANETs) as a special case of the more generic Mobile Ad hoc NETworks (MANETs). A public transportation network used as a VANET backbone may be a viable solution - under certain circumstances - also thanks to its almost-complete area coverage and the pre-scheduled repetitive paths. The...
Owing to the technological advances in computing power and wireless communications, applications that used to be only accessible on desktop computers are increasingly run-able on wireless devices. As a result, a wireless device user may run several applications at the same time, and these different applications may generate different data types. In a mobile ad hoc network (MANET) environment, which...
With continuously development of the ad hoc network technology, integrating with other networks becomes one of the trends. Due to the involvement of other networks, routing strategy needs to change with the development. To considerate the key factors whose influence are serious comprehensively is needed. For those reasons, this paper proposes a novel concept of the optimal routing function, which...
Some of multi-path routing algorithms in MANETs use multiple paths simultaneously. These algorithms can attempt to find node-disjoint to achieve higher fault tolerance. By using node-disjoint paths, it is expected that the end-to-end delay in each case should be independent of each other. However, because of natural properties and medium access mechanisms in ad hoc networks, such as CSMA/CA, the end-to-end...

A new rate expression of node entering/leaving spindle region beta has been established by analyzing...
In a mobile ad hoc network, where nodes are deployed without any wired infrastructure and communicate via multihop wireless links, the network topology is based on the nodes' locations and transmission ranges. The nodes communicate through wireless links, with each node acting as a relay when necessary to allow multihop communications. The network topology can have a major impact on network performance...
Rapid advancement in wireless communication has made it possible to develop vehicular ad hoc networks, in which a vehicle can communicate with other vehicles via a wireless, multi-hop fashion. A variety of appealing real-world applications can be enabled by VANETs, such as driving safety and urban monitoring. Many location based routing algorithms have been proposed for data delivery in VANETs. Most...

A game theoretic method, called collaborative On-line Game Playing, is to execute a collaborative application in dense multi-hop MANET (mobile Ad Hoc network). The players of the game collaborate together with their neighbors, each moving towards next arbitrary position at any time. In the network, data should be distributed reliably and efficiently among hosts for consecutive playing with limited...
