This paper describes a cooperative MANET protocol dedicated to intelligent transportation systems and its new experiment results in mobile scenarios. The protocol is named CIVIC (Communication Inter Veacutehicule Intelligente et Coopeacuterative). It is an auto-configuration inter-vehicle communication protocol, which supports ad-hoc and infrastructure networks, contains reactive and proactive routing...
Wireless sensor networks are subject to energy restriction compared with other wireless networks. To support a ubiquitous environment, a mobile sink has a lot of problems because it collects data while moving. TTDD is a representative routing protocol considering Mobile sink. It uses a lot of control packets, all of which are transmitted through agent nodes. This causes agent nodes to waste a lot...
An evolution of a hardware technology makes it possible to deploy lightweight and multi-functional mobile devices in a real environment. Wireless sensor networks (WSN) are representative networks using these tiny and low-power sensor devices. Two types of communications occur in sensor networks: one is between end nodes, and the other is between end node and base station (BS). Since not only the resource-restriction...
In this study we develop a hybrid (dual- strategy) routing protocol for wireless sensor networks. This protocol can be used for two purposes at the same time. First, the protocol is responsible for routing data within sensor networks. These networks are composed of nodes with different capabilities and resources. The routing in this case is data-oriented. That is, it searches for nodes that can provide...
