In the near future microprocessors will be found almost everywhere from cellular phones to washing machines and cars. Once these are connected via a (wireless) communication channel to each other and possibly to already existing static computers this could form an extremely dynamic wireless network which may not have access to an infrastructure or centralized administration. Such a network is o...

Quality of Service (QoS) provisioning and management in ad hoc networks remains a challenging task. Existing research focuses either on providing QoS or on network management, in ad hoc networks. However, a comprehensive approach to QoS management in ad hoc networks, i.e. network management in support of service differentiation, QoS robustness, and network survivability is still lacking. In thi...

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...

Vehicular ad hoc networks (VANETs) are a particular type of Mobile ad hoc networks (MANET) in which the vehicles are considered as nodes. Due to rapid topology changing and frequent disconnection makes it difficult to design an efficient routing protocol for routing data among vehicles. In this paper, a new routing protocol based on glowworm swarm optimization algorithm is provided. Using the g...

content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

Networks have become an integral part of all communications, associations, businesses, services, government/public organizations and human interactions around the globe. Emergence of technologies and dynamism of user needs & access pattern of network resources have shifted paradigm to wireless ad-hoc network infrastructure supporting mobile devices. Ad-hoc networking means building spontaneous ...

Ad hoc networks may be viewed as computational systems whose members may fail to, or choose not to, comply with the rules governing their behaviour. We are investigating to what extent ad hoc networks can usefully be described in terms of permissions, obligations and other more complex normative relations, based on our previous work on specifying and modelling open agent societies. We now propo...

A mobile ad hoc network is an autonomous wireless network which consists of mobile nodes without any base stations. Many routing schemes and services have been proposed for mobile ad hoc networks. However, since these schemes tend to be evaluated through simulation experiments, it is not known whether they work effectively in real environments or not. Therefore, in order to verify their practic...

Wireless ad-hoc networks are infrastructureless networks in which heterogeneous capable nodes assemble together and start communicating without any backbone support. These networks can be made truly dynamic and the nodes in these networks can move about freely while connecting and disconnecting with other nodes in the network. This property of ad-hoc networks to self-organize and communicate wi...
