In wireless sensor networks, many studies on data dissemination to individual mobile sinks traditionally rely on a strategy that consists of a virtual infrastructure to serve current location of the mobile sinks and a per-sink foot-print chaining mechanism to support local mobility after location update. To adapt the strategy for supporting mobile sink groups, it may be simply considered to exploit...
Rumor Routing is one of the routing algorithm categories in wireless sensor networks which is well extended and optimized in the recent years. Common principal ideas in all rumor routing algorithms are conjunction of query-agents with the traversed path of event information propagator agents in the network. In this paper we propose a new method to reduce the number of routing agents to consequently...
Wireless sensor network which is composed of a large number of low-cost, low-power, multifunctional sensor nodes deployed in a remote environment to monitor and analyze the data collected in the physical world in a timely manner. Based on the feature of nodes with limited energy, people have done some deep research on the prolongation of the lifetime in the WSN. In this paper, we focus on reducing...
This paper presents CARNIVORE, a system for in-situ, yet unobtrusive monitoring of cryptic, difficult-to-catch/observe wildlife in their natural habitat. CARNIVORE consists of a network of mobile and static nodes that have sensing, processing, storage, and wireless communication capabilities. One of CARNIVORE'S notable novel features is its robustness to intermittent node connectivity since, depending...
In sparse mobile sensor networks, nodes have a small number of neighbors with intermittent connectivity. This paper presents a new networking protocol for this type of network, aimed at maximizing system performance in terms of both delay and reliability. The system is motivated by the observation that many applications on this type of network have two kinds of co-existing data packets: those with...
Most of the work on geocasting has been done for mobile ad-hoc networks and vehicular ad-hoc networks. This paper presents a novel Geocast technique with the hole detection in the geocast region for underwater environment. The proposed model named as Routing and Multicast Tree based Geocasting (RMTG) has been designed for underwater sensor networks. Here we propose a theoretical model for underwater...
There have been proposed many geographic multicasting protocols for wireless ad hoc sensor networks. Most of these protocols tend to exploit a Source-initiated Geographic Multicasting (SGM) approach which consists of three phases: first, a source collects the position information of all destination nodes; second, the source constructs a multicast tree through the position information; third, the source...
Mobile sink Wireless Sensor Network (MSWSN) has recently received a lot of attention from the research community. Its appealing characteristics of providing longer network lifetimes, delay optimizations and the flexibility to adapt dissemination strategies according to applications' requirements have proved to be more efficient. Numerous mobile sink based data dissemination strategies have been proposed...
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...
In directed diffusion, sensor nodes send interest/exploratory data messages for setting up paths by flooding. This flooding approach consumes high amount of energy in the network. Accordingly, some research work in the literature studies how to solve this flooding problem focusing on the interest messages. Little work has been done on reducing the exploratory data. In this paper, we propose a new...
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...
This paper presents a cluster-based self-organizing algorithm for creating automatically ad-hoc networks including diverse wireless devices such as PDA, cell phones, laptops, wireless sensors, etc. In the proposed strategy each mobile device is represented by a multi-role agent, which generates a backbone among the devices within the environment based only on local interactions. During the operation...
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...
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...
