“…But this feature may also be provided by other geographical overlay structure. For example, LL-Net [4] has hierarchical overlay network structure that divides entire space into multiple levels of four squares. By using this hierarchy, the messages can be distributed to the target area with uniform distribution by selecting one node inside the square at required hierarchy level.…”

Geographical contour lines are often used for the analysis of the sensor data distribution on wide area. In this paper, we propose a method to reconstruct contour lines by collecting sensor data from widely distributed sensors. In this case, it is redundant to collect all sensors from wide area since geographically closed sensors sense similar data. We propose a sensor data collection method for peer-to-peer sensor network to realize spatial interpolation of sensor data. In our proposal, we assume hierarchical Delaunay overlay network (HDOV) to collect sensor data uniformly. In addition, using structure of HDOV, more local sensor data is collected that affect on the spatial interpolation. By this mechanism, redundant sensor data to reconstruct geographical contour lines is reduced. The simulation result shows that our proposal can reconstruct accurate geographical contour lines, reducing target node and message numbers for data collection.

“…SLABSp [22] uses scenario rules to specify interactions among agents in patterns of action sequences, but it has little support for message correlation, fault tolerance and load balancing. PIAX [23] is a framework that integrates mobile agent based messaging and peer-topeer discovery mechanisms transparently with application layer multicasts. Channeled Multicast [24] uses themed multicast to facilitate the specification of interaction protocols, while Owlet provides a more expressive means by using content-based publish/subscribe interaction scheme.…”

There is an increasing need to build scalable distributed systems over the Internet infrastructure. However, the development of distributed scalable applications suffers from lack of a wide accepted virtual computing environment. Users have to take great efforts on the management and sharing of the involved resources over Internet, whose characteristics are intrinsic growth, autonomy and diversity. To deal with this challenge, Internet-based Virtual Computing Environment (iVCE) is proposed and developed to serve as a platform for distributed scalable applications over the open infrastructure, whose kernel mechanisms are on-demand aggregation and autonomic collaboration of resources. In this paper, we present a programming language for iVCE named Owlet. Owlet conforms with the conceptual model of iVCE, and exposes the iVCE to application developers. As an interaction language based on peer-to-peer content-based publish/subscribe scheme, Owlet abstracts the Internet as an environment for the roles to interact, and uses roles to build a relatively stable view of resources for the on-demand resource aggregation. It provides language constructs to use 1) distributed event driven rules to describe interaction protocols among different roles, 2) conversations to correlate events and rules into a common context, and 3) resource pooling to do fault tolerance and load balancing among networked nodes. We have implemented an Owlet compiler and its runtime environment according to the architecture of iVCE, and built several Owlet applications, including a peer-to-peer file sharing application. Experimental results show that, with iVCE, the separation of resource aggregation logic and business logic significantly eases the process of building scalable distributed applications.

In the ubiquitous computing environment, we believe that P2P-based context-aware application utilizing sensing data is important. However, since sensors are not placed under the control of one specific entity, it is difficult to retrieve appropriate information from the distributed sensors. In addition, when the same queries are sent by different users, same processes for collecting sensing data are repeated. The repetitive processing causes a load increase of sensors and network. In this paper, we propose a P2P-based architecture for managing distributed sensor information, which treats sensing data based on those semantic. The proposed architecture is constructed of three layers, 'Raw Layer', 'Abstract Layer' and 'Logical Layer', which enables to generate necessary information from retrieved data semantically. In addition, we propose a method to create virtual sensors by real peer. The virtual sensor manages processed data as a cache of real sensing data. We implemented the proposed architecture and method on PIAX, which is a development platform for agent-based P2P system. Then we evaluated the proposed virtual sensor placement method by simulations. By the simulation results, we confirmed that proposed method achieve a context-aware application with reducing the amount of network traffic.
