In ad hoc networks, the flooding is used to deliver message to the whole network. However, excessive use of flooding generates a large number of redundant packets, and it gives heavy traffic load to the network. To solve this problem, many schemes have been proposed. But since those studies do not take into account the actual load condition of each node that will affect network efficiency, not so...
Power dissipation is a crucial issue for integrating more than billions transistors on a chip. At the same time, reduction in energy consumption will be an essential subject to build future networking environment evolutionarily. This research project proposed in this paper is aiming at developing a data-driven networking system by which the coming networking environment can be realized with ultra-low-power...
We tackle the problem of video multicast over mobile ad hoc networks in this paper using multiple trees multicast routing protocol. More specifically, we propose an extension to the Multicast Ad Hoc On-Demand Distance Vector (MAODV) to construct two highly-disjoint trees in a single routine; we called it Multiple-Tree Multicast Ad Hoc On-Demand Distance Vector (MT-MAODV) routing protocol. By using...
Over the last decade, mobile ad hoc networks have emerged as a promising solution for providing ubiquitous communications to support various multimedia applications. Supporting video over infrastructureless mobile ad hoc networks is more challenging than over other networks due to the absence of fixed infrastructure and rapid changes in network topology. In this paper, we study the feasibility of...
This paper proposes the necessity of the secure, ad hoc and ubiquitous communication environment that is integrating personal authentication and usage right management onto the mobile ad hoc network, which is an infrastructureless network suitable to the emergency cases. To implement this environment, this paper studies technical requirements to each layer and among them it proposes two basic ideas...
This paper tackles the problem of interactive video transmission over wireless ad hoc networks. We propose a mechanism using multiple sources to transmit interactive video coded with multiple description coding (MDC) scheme over wireless ad hoc networks. MDC is a coding scheme that provides greater flexibility for video coding. Simulation study has been carried out using discrete event simulator to...
