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 this paper we explore the mobility of a mobile sink in a wireless sensor network (WSN) to prolong the network lifetime. Since the mechanical movement of mobile sink is driven by petrol and/or electricity, the total travel distance of the mobile sink should be bounded. To minimize the data loss during the transition of the mobile sink from its current location to its next location, its moving distance...
Securing a Wireless Ad Hoc Network is one of the major concerns for the researchers. Due to wide-ranging characteristics of the ad-hoc networks, it is always at a risk to internal as well as external attacks. Many solutions have been proposed and currently being improved in this area. Most of these solutions involve encryption, secure routing, quality of service etc. Each of them is designed to operate...
The open medium, dynamic topology, and multi-hop cooperative routing of vehicular ad hoc networks (VANETs) make it facing more security challenge than wired networks. In this paper, a hierarchical VANETs intrusion detection system based on BUSNet is present. BUSNet is basically a virtual mobile backbone infrastructure that is constructed using public buses. We use the bus nodes as the cluster-heads...
A wireless sensor network is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor/control physical or environmental conditions, such as temperature, pressure or motion, at different locations. Main processing center gather information from remote locations while centrally controlling those centers. Reliability of communication can be achieved...
We present an analytical model combining geometric and stochastic approaches to describe the effects of attacks and countermeasures on MANETs. In particular, we focus on the packet loss that can be charged to the misbehavior as well as to the countermeasures as a primary metric. For this, we model the entire chain of (1) MANET routing, (2) attack, (3) intrusion detection, and (4) intrusion response...
Mobile ad hoc network is a special peer-to-peer network with a wide range of application that has no infrastructure, multi-hop, self-organizing, dynamically reconfiguration and mobile. People are now paying more and more attention to the using of ad hoc network in the emergence area such as battlefield and disaster rescue. The research on its energy and security are one of the most important aspects...
The traditional Wireless Sensor Network (WSN) with fixed nodes canpsilat server the newly demand any more. For adapting to the future sensor network, we proposed a novel Multi-tier mobile network architecture; studied the problems of instability of network and high-fraction of event loss caused by the mobility of tiered nodes and mobile Fusion (F) node routes for data collection. For computing mobile...
Low-cost wireless routers are changing the way people connect to the Internet. They are also very cheap, albeit quite limited, Linux boxes. These attributes make them ideal candidates for wireless mesh routers. This paper presents a minimally invasive mechanism for redundant multipath routing in kernel-space to achieve high reliability with high throughput in a mesh network. This service is essential...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
