A mobile ad hoc network is a collection of digital data terminals equipped with wireless transceivers that can communicate with one another without using any fixed networking infrastructure. Communication is maintained by the transmission of data packets over a common wireless channel. The absence of any fixed infrastructure, such as an array of base stations, make ad hoc networks radically dif...

Mobile ad hoc networks are dynamically organized by a collection of wireless mobile nodes. The mobile nodes in ad hoc networks can move arbitrarily thus the topology of network changes dynamically. Due to the properties of communication medium in wireless networks, unidirectional links may exist between mobile nodes thus results in the difficulty of link utilization and routing. In this paper, ...

The growing availability of networked mobile devices has created a vast collective potential of unexploited resources. Grid computing with its model of coordinated resource sharing may provide a way to utilize such resources that are normally distributed throughout a mobile ad-hoc network. In this paper, we explore the challenging operation of Grid computing in mobile ad-hoc networks which are ...

Mobile Ad Hoc Network (MANET) is an autonomous system of mobile wireless nodes connected dynamically without any preexisting infrastructure. A fuzzy QoS controllers based priority scheduler for mobile ad hoc networks is presented to determine the priority of the packets. The performance of this scheduler is studied using NS2 and evaluated in terms of quantitative metrics, such as packet deliver...

Most previous work on real-time event-based communication has assumed infrastructure-based networks. The underlying assumption of this work is that application components are stationary and that a fixed network infrastructure exists to facilitate communication between them [1]. Ad hoc wireless networks comprise sets of mobile nodes connected by wireless links that form arbitrary wireless networ...

A mobile ad hoc network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. Mobile ad-hoc networks are the autonomous systems of mobile nodes forming network in the absence of any centralized support. Although establishing correct and efficient routes is an important d...

Mobile ad hoc networks (MANETs) are formed by mobile nodes without the support of fixed infrastructure. In the MANET, each node performs as a host as well as host to forward the data packets. The nodes are adjustable based on the local environments. MANETs are used in many situations where temporary network connection is needed. In this paper, investigates the problem of lifetime enhancement of...

An ad hoc network is a dynamically reconfigurable wireless network with no fixed infrastructure or central administration. Each host is mobile and must act as a router. Routing and multicasting protocols in ad hoc networks are faced with the challenge of delivering data to destinations through multihop routes in the presence of node movements and topology changes. This paper presents the On-Dem...

This paper outlines some important issues that relate to security attacks against mobile ad hoc networks from research carried out at Network Research Group, University of Plymouth, on designing intrusion detection system for mobile ad hoc network. In designing security mechanisms for mobile ad hoc networks, one must consider the attacks variations as well as the characteristics of the attacks ...

In this paper, we propose an architecture for provisioning nondisrupted QoS guarantees in mobile ad hoc networks, and extend the scalable resource reservation protocol (SRRP) for signaling in ad hoc networks. In particular, we present a number of techniques that can enable QoS guarantees in ad hoc networks, including geographical reservation and clusterhead election (GRACE), the request-to-rese...
