In this paper, we propose a secure incentive scheme to achieve fair and reliable cooperative (SIRC) downloading in highway vehicular ad hoc networks (VANETs). SIRC can stimulate vehicle users to help download-and-forward packets for each other and consists of cooperative downloading and forwarding phase. During the cooperative downloading phase, SIRC utilizes “virtual checks” associated with the designated...
Mobile ad hoc network (MANET) is a distinct kind of network where the nodes are connected by way of wireless medium and without any infrastructure. Nodes in the network are fully dependent on other nodes so as to complete the mission successfully. In addition to this, nodes are moving freely and make dynamic topology. Moreover these types of networks can be easily constructed whenever and wherever...
Userspsila authentication and authorization to services access are two important challenges standing against the deployment of ad hoc networks by networks operators. In this paper we consider ad hoc networks real deployment scenarios, in which advanced services are provided to users (ex, multimedia services, audio-visual services, remote control services), and nodes cooperate allowing services provision...
