The spatiotemporal and just-in-time mobile multicast routing protocol of Wireless Sensor Network, such as Mobicast, which has the perfect usefulness in monitoring Mobile entities, Communications with higher security requirements. Most of the existing Mobicast routing protocols is focused on the group key distribution and management, but also realized under the conditions of static grouping, which...
In this paper we present ROME, a geographic routing protocol for wireless sensor networks (WSNs) with mobile nodes. ROME design is suited to deal with communication problems in WSN scenarios with high network dynamics, such as nodal addition, nodal removal and node mobility. In addition, it retains desirable properties of protocols for static WSNs such as using cross-layer techniques for performance...
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...
In many applications of sensor-equipped mobile vehicle networks, an energy-efficient communication solution is required due to the limited battery on the vehicle. There are certain characteristics of vehicle-based networks that set them apart from typical sensor networks, namely that they are mobile and consist of only a few nodes. We adopt a design philosophy that optimizes the networking approach...
As the non-stop development of wireless sensor network, its application was enormous. Control network based on forest anti-fire was one of the application fields. This paper made simulation on several scenarios in order to produce the best effect on data collecting and transmission, including different setting pattern of sensor nodes, the amount of nodes and their movement pattern. All of them were...
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...
Presently, there are many research work for sensor networks. In our previous work, we implemented a simulation system for sensor networks. But, we considered that the event node is stationary in the observation field. However, in many applications the event node may move. For example, in an ecology environment the animals can move randomly. In this work, we want to investigate how the sensor network...
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...
Sink mobility brings new challenges to densely deployed and large wireless sensor network. When the sink moves, frequent location updates from the sink can generate excessive power consumption of sensors. In this paper, we propose OAR, an optimized agent-based routing protocol that provides efficient data delivery to mobile sink. Proposed algorithm reduces signaling overhead and improve degraded route...
In this paper, we efficiently adapt the prominent Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a reactive Local Link Repair, AODV-LR, for effective deployment in restricted power-budget and bandwidth mobile ad hoc sensor networks (MASNET). We introduce a better replacement mechanism to the local repair phase of the AODV. Our new approach is a preemptive, self-repairing AODV (called...
Wireless networks have become increasingly popular and advances in wireless communications and electronics have enabled the development of different kind of networks such as mobile ad-hoc networks (MANETs), wireless sensor networks (WSNs) and wireless sensor-actor networks (WSANs). These networks have different kind of characteristics, therefore new protocols that fit their features should be developed...
Mobile wireless sensor network (M-WSN) is wireless sensor network without infrastructure, and includes mobile nodes. According to certain mobility models, mobile nodes move around in the network, and change their locations continually. Because the paths between nodes are not fixed any more, it normally takes nodes longer time to communicate each other. To solve this problem in the M-WSN, this paper...

In tactical applications of wireless sensor networks (WSNs), such as intruder detection, tracking, and patrol operations, there tend to be multiple, mobile end-users who work amidst the sensors in the field to which data from individual sensors must be directly delivered. Efficient data dissemination in such networks is a challenging problem, since sensors with detections must be able to identify...
In this paper, we present two new ldquospatiotemporal multicastrdquo protocols for supporting applications which require spatiotemporal coordination in sensor networks. The spatiotemporal character of mobicast relates to the obligation to deliver a message to all the nodes that will be present at time t in some geographic zone Z, where both the location and shape of the delivery zone are a function...
In wireless sensor networks, the routing algorithms currently available assume that the sensor nodes are stationary. Therefore when mobility modulation is applied to the wireless sensor networks, most of the current routing algorithms suffer from performance degradation. The path breaks in mobile wireless networks are due to the movement of mobile nodes, node failure, channel fading and shadowing...
Research on wireless sensor networks has recently received much attention as they offer an advantage of monitoring various kinds of environment by sensing physical phenomenon. Among various issues, energy consumption is one of the most important criteria for routing protocol in wireless sensor networks (WSNs). This paper introduces an energy efficient clustering algorithm for mobile sensor network...
Intermittent connected mobile sensor networks (ICMSN) have emerged in recent studies, e.g. underwater sensor networks, wildlife tracking and human-oriented flu virus monitoring. In these networks, there are no end to end connections from sensor nodes to sink nodes due to low node density and node mobility. Therefore, conventional routing protocols in WSN are not practical for ICMSN since packets will...
The growing popularity of location-enabled devices has driven the demand for more efficient and reliable geographical routing algorithms for mobile ad hoc networks (MANET) and wireless sensor networks. The characteristic of this network is that nodes exchange geographical location with neighbors, and no global topology or central management is required. This paper proposes a hybrid approach for routing...
In recent years, mobile network has evolved greatly with the existences of MANET, wireless sensor network, mobile IP, NEMO and etc. The advent of network mobility (NEMO) tends to provide seamless Internet connectivity to all the nodes within a mobile network regardless of their current points of attachment with the usage of a mobile router. Multicasting support is one of the key technologies in next...
