“…By combining light-trails with PIC we are able to achieve the dual of service support without compromising on reach. This merged technology concept is called LiTPiC [1] and as the name suggests, we inculcate PICs in a light-trail. To do so, each light-trail node is modified to include PIC technology thereby regenerating the optical signal as it passes through the node while maintaining bus features -necessary for application support.…”

LiTPiCs were proposed as a marriage of two innovative technologies -light-trails and photonic integrated circuits -as a solution to extend metro networks in regional domains and provide dynamism in bandwidth allocation for emerging services. Light-trails which are a generalized lightpath, essentially formed by an optical bus provide sub-wavelength optical grooming and facilitate dynamic bandwidth allocation amongst constituent nodes. Communication within a light-trail is all-optical thereby limiting their reach to a few node-spans. In parallel, photonic integrated circuits were developed that proposed the system on a chip concept enabling 3R regeneration of optical signal using embedded lasers and receivers on a single Indium Phosphide substrate. PIC technology has given rise to the concept of digital optical networks -which have the capability to increase reach and commoditize metro networks. By conjoining the light-trail and PIC technologies we proposed LiTPiC which is essentially preserves light-trail properties while enhancing their reach. In this paper we study algorithms for scheduling traffic in a LiTPiC. We consider both the static case and the dynamic case -when traffic is known and not known apriori. Further we will establish a lower and upper bound that would facilitate an evaluation procedure of our algorithms.

Using structured data formats like XML in wireless sensor networks to support exchangeability and heterogeneity on application level has become an important research topic in the area of large scale networked sensing systems. Besides, the usage of XML encourages the adaptation of service oriented programming techniques to simplify sensor network application engineering. While the sensor nodes still have significant resource limitations in terms of energy and memory capacity and computational power, recent data management approaches show positive results to bridge this resource gap. Nevertheless, further optimizations are needed to enhance the application range to support larger sets of data within the networks. In this work we present an optimization for a template object compression scheme that is based on a stream-oriented XML compression and supports dynamic data management and query evaluation on the compressed data. We hereby present a complete solution for XML compression, data processing and query evaluation that can be further embedded in the engineering process to support developers. The presented solutions are evaluated and result into significant improvements in comparison to previous approaches, when processing complex large scale XML documents.
