A new scheme that serves to find a routing path for Wireless Sensor Networks (WSNs), with a view to facilitate an increase in the network life time is proposed in this paper. It envisages the network to be in the form of clusters and develops an algorithm for transfer of information within the nodes and to the remote Base Station (BS). The approach involves the use of Ad-hoc On Demand Distance Vector...
This paper presents a cross-platform solution of smartphone-based mobile sink for wireless sensor networks, named uSink. With a cross-platform SD card, named uSD card, any smartphone with SD interface can be empowered with the capability to communicate with wireless sensor nodes. Furthermore, a middleware on mobile phone, named uSinkWare, is also designed to provide a typical mobile sink's functionalities,...
In many typical wireless sensor networks, the nodes are fixed, where cluster based protocols like LEACH were suitable for routing. However, it is another story when the nodes are mobile. This paper proposes a novel routing protocol supporting node mobility called “2L-LEACH-M”, it divides the nodes into two levels: level 1 (cluster-head level) or level 0 (member level), which makes mobile nodes find...
Applications for wireless sensor networks have grown enormously over the past few years. Routing and sink discovery protocols designed for ad hoc networks do not adapt to sensor networks, and generic sensor network routing techniques are not optimal for all scenarios. We propose a light weight routing protocol to discover mobile sinks in battle-field operations or large terrains. Initial experimentation...
The emergence of ubiquitous communication helps make safer and unobstructed street. Sensor detection is a valid technology to collect and process traffic data (vehicular speed, vehicle density, images from street) with the help of equipped sensors under the road or installed along the street. Vehicular sensor network (VSN), developed from wireless sensor network (WSN), is characterized by unlimited...
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...
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...
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...
Mobile ad hoc networks (MANET), which comprise of mobile nodes connected wirelessly, are emerging as a very important technology for future generation of wireless mobile and ubiquitous computing. MANETs are being used in numerous application domains from emergency rescue and relief to wireless sensor networks. To support real-time communications (such as audio and video) over MANETs, new quality of...
In this paper, we propose a novel coalitional game model for security issues in wireless networks. The model can be applied to not only mobile ad hoc networks but also wireless sensor networks. We define a new throughput characteristic function, on the basis of which nodes are enforced to cooperate and form coalitions. This function implies the maximal throughput and the most reliable traffic that...
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 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...
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...
LEACH and LEACH-C have demonstrated the feasibility of achieving good efficient routing path. As considering mixed sensor fields with fixed and mobile nodes in a sensor field LEACH and LEACH-C are not appropriate to support mobile sensor nodes. In this paper, we proposed an algorithm, called "minimal hop count path routing algorithm", for mobile sensor nodes on mixed sensor fields using...
