In old times, castles were surrounded by moats (deep trenches filled with water, and even alligators) to thwart or discourage intrusion attempts. One can now replace such barriers stealthy wireless sensors. this paper, we develop theoretical foundations for laying of We define the notion k-barrier coverage a belt region using propose efficient algorithms which one quickly determine, after deploying sensors, whether is covered. Next, establish optimal deployment pattern achieve when sensors...
Sensor networks are often desired to last many times longer than the active lifetime of individual sensors. This is usually achieved by putting sensors sleep for most their lifetime. On other hand, surveillance kind applications require guaranteed k-coverage protected region at all times. As a result, determining appropriate number deploy that achieves both goals simultaneously becomes challenging problem. In this paper, we consider three kinds deployments sensor network on unit square - √n...
It is well-known that placing disks in the triangular lattice pattern optimal for achieving full coverage on a plane. With emergence of wireless sensor networks, however, it now no longer enough to consider alone when deploying network; connectivity must also be con-sidered. While moderate loss can tolerated by applications fatal. Moreover, since sensors are subject unanticipated failures after deployment, not have network just connected, should k-connected (for k > 1 ). In this paper, we...
The decreasing cost along with rapid progress in next-generation sequencing and related bioinformatics computing resources has facilitated large-scale discovery of SNPs various model nonmodel plant species. Large numbers genome-wide availability make them the marker choice partially or completely sequenced genomes. Although excellent reviews have been published on sequencing, its associated challenges, applications genetic studies, a comprehensive review connecting these three intertwined...
Mobile health technology has great potential to increase healthcare quality, expand access services, reduce costs, and improve personal wellness public health. However, mHealth also raises significant privacy security challenges.
Project ExScal (for extreme scale) fielded a 1000+ node wireless sensor network and 200+ peer-to-peer ad hoc of 802.11 devices in 13km by 300m remote area Florida, USA during December 2004. In comparison with previous deployments, the application is relatively complex its networks are largest ones either type to date. this paper, we overview key requirements ExScal, corresponding design hardware/software platform application, some results our experiments.
Global barrier coverage that requires much fewer sensors than full coverage, is known to be an appropriate model of for movement detection applications such as intrusion detection. However, it has been proved given a sensor deployment, can not locally determine whether the deployment provides global making impossible develop localized algorithms, thus limiting its use in practice.

Deriving the critical density (which is equivalent to deriving radius or power) achieve coverage and/or connectivity for random deployments a fundamental problem in area of wireless networks. The probabilistic conditions normally derived, however, have limited appeal among practitioners because they areoften asymptotic, i.e., only make high probability guarantees limit large system sizes. Such are not very useful practice since deployment regions always finite. Another major limitation most...
To make a network last beyond the lifetime of an individual sensor node, redundant nodes must be deployed. What sleep-wake-up schedule can then used for so that redundancy is appropriately exploited to maximize lifetime? We develop optimal solutions both problems case when wireless are deployed form impenetrable barrier detecting movements. In addition being provably optimal, our algorithms work nondisk sensing regions and heterogeneous regions. Further, we provide solution more difficult...
With increasing popularity of media enabled hand-helds, the need for high data-rate services mobile users is evident. Large-scale Wireless LANs (WLANs) can provide such a service, but they are expensive to deploy and maintain. Open WLAN access-points (APs), on other hand, no new deployments, offer only opportunistic with guarantees short term throughput. In contrast, carefully planned sparse deployment roadside WiFi provides an economically scalable infrastructure quality service assurance...
Tracking of movements such as that people, animals, vehicles, or phenomena fire, can be achieved by deploying a wireless sensor network. So far only prototype systems have been deployed and hence the issue scale has not become critical. Real-life deployments, however, will at large achieving this prohibitively expensive if we require every point in region to covered (i.e., full coverage), case deployments. In paper therefore propose new model coverage, called trap scales well with deployment...
The problem of sleep wakeup has been extensively studied for the full coverage model, where every point in deployment region is covered by some sensor. Since sleep-wakeup NP-Hard this several heuristics exist. For model barrier coverage, however, sensors are deployed to form an impenetrable detecting moving objects (a flagship application wireless sensor networks), design optimal algorithm open. In paper, we solve open proposing algorithms not only often-used case equal lifetime but also...

Using an in situ deployment, however, such does not worst-case performance guarantees due unpredictable intermittent connectivity. On the other hand, that tries cover every point entire road network with APs (full coverage) is very practical prohibitive deployment and operational cost.

Majority of papers in the area wireless sensor networks (WSNs) have an element energy-efficiency and associated with it analysis network lifetime. Yet, there is no agreement on how to analyze lifetime a WSN. As result, errors are frequently made both sides. Some underestimate by order magnitude, while others end up overestimating significant factor. This paper presents first step towards standardizing WSNs. We focus WSNs deployed for always-on applications, where problem power management...
Although random deployment is widely used in theoretical analysis of coverage and connectivity, evaluation various algorithms (e.g., sleep-wakeup), it has often been considered too expensive as compared to optimal deterministic patterns when deploying sensors real-life. Roughly speaking, a factor log n additional are needed if deployment. This may be an illusion however, since all real-life large-scale deployments strategies result some randomness, two prime sources being placement errors...
