In this paper, underwater sensor network with static sensor nodes is applied in environmental monitoring. the scope of underwater sensor applications can be enhanced by combining underwater sensor network and cloud computing. the underwater sensor cloud management is done by proposing a middleware based on metamodeling. the underwater sensor cloud architecture provides a way for underwater sensor motes to collect, store and retrieve environmental data. the proposed Hadoop framework serves as a middleware for underwater sensor cloud. the middleware that is been considered to use in our research is an intelligent context-aware middleware software that will glue together the network hardware, operating systems, network stacks and applications. It contain a runtime environment that supports and coordinates multiple applications based on multi-agents, and standardized system services such as data aggregation, control and management policies. Underwater sensor cloud framework enables to Extract knowledge from the data it collects and use the information to intelligently react and adapt to its surroundings. It links a remote end user's cognizance withthe observed environment. sensor Web is an amorphous network, creating an embedded, distributed monitoring presence that provides a dynamic infrastructure for sensors. Reduce the Labor effort and have continuous monitor of the environment Provide more intensive and accurate data on the current status of the environment and reduces the reaction time towards the environmental changes Since there is no specific routing of information, all pods share everything with one another. this global data sharing allows each pod to be aware of situations beyond its specific location Usage of historical data to predict future actions and foresee the disaster to be caused quickly and more precisely Framework can support extensibility, easy maintainability and control over the sensors deployed
Energy efficiency is one critical issue for sensor networks because many sensors are equipped with batteries that have limited life time. this paper is focused on Opportunistic routing which is a recent technique that...

As embedded networks are evolving to open systems, it's becoming possible to create new applications on top of these existing embeddedsystems. However, developing new applications can be difficult due to the large diversity of protocols that exist today. In this paper, the authors demonstrate how employing the CoAP protocol can enable rapid application development by re-using well-known principles from the Web development world. Furthermore, we also demonstrate how a number of extensions to CoAP help to lower the barrier for developing applications even further.

the information-preserving sampling properties of compressive sensing have found a number of successful applications, such as sensor scheduling, localisation and tracking to deal withthe resource constraints of the embeddedsystems. In this paper, we investigate an approach to improve the performance of compressive sensing applications through a novel strategy for optimising the projection matrix. We formulate the projection matrix optimisation problem and apply greedy algorithm to solve the optimisation problem efficiently. We evaluate the proposed approach by an emerging background subtraction method designed specifically for the embeddedsystems and show the proposed approach outperforms existing approaches significantly with little overhead.

the poor performance of TCP over wireless and lossy links has hindered its use in low power networks. the Low Power Wireless Bus (LWB) offers high reliable and low latency communication in IEEE 802.15.4 networks. In this paper, we argue that TCP can be used to provide reliable connectivity between sensor nodes in an LWB-based sensor network and external Internet hosts.

In this paper we introduce a novel sophisticated collusion attack scenario against a number of existing iterative filtering algorithms. To address this security issue, we propose an improvement for iterative filtering techniques by providing an initial approximation for such algorithms which makes them not only collusion robust, but also more accurate and faster converging.

In wireless sensor networks (WSNs), random failures at the sensor nodes and the communication level reduce the likelihood of completing a prescribed mission. this likelihood is further reduced when geographically correlated failures affect the sensing and communication capabilities of the network. In this work, a mission allocation algorithm for WSNs accounting for geographically correlated failures is proposed. the algorithm maximizes the likelihood of completing a mission in WSNs by allocating resources onto the sensor nodes according to a score that weighs the resources, the availability, and the likelihood of sensor nodes to be affected by geographically correlated failures.

this poster presents the work done to monitor the structural health of a Rome B1 underground construction site through a battery-powered Wireless sensor Network (WSN). We illustrate the specific requirements and challenges of working with wireless sensors underground, and we describe the solutions adopted for obtaining a working WSN that provides a robust solution of on line monitoring. We conclude by presenting an assessment and testing of these solutions, along withthe design insights and the lessons we learned during this on-the-field experience.
