A Data Delivery Strategy in Ubiquitous Computing Systems

چکیده
Browsing web pages through wireless devices will become more and more popular in the near future. However; accessing a large chunk of web data incurs a great amount of access latency while a mobile user (MU) migrates across cells. This paper investigates this problem and proposes an effective way of delivering such data to the MU in the ubiquitous computing systems. Our Data Delivery (V’) strategy is based on the dynamic programming skill to preassign the user requested data on the possible visiting cells in order to reduce the access latency. We first design an encoding method for the cells, and then derive the properties of the encoding scheme. These properties are then used in our algorithm to deliver the data. Finally, experiments are conducted to demonstrate the feasibility and efJiciency of the proposed method.

Algorithms for Computing Limit distributions of Oscillating Systems with Finite Capacity
We address the batch arrival systems with finite capacity under partial batch acceptance strategy where service times or rates oscillate between two forms according to the evolution of the number of customers in the system. Applying the theory of Markov regenerative processes and resorting to Markov chain embedding, we present a new algorithm for computing limit distributions of the number cus...

With the formation of the competitive electricity markets in the world, optimization of bidding strategies has become one of the main discussions in studies related to market designing. Market design is challenged by multiple objectives that need to be satisfied. The solution of those multi-objective problems is searched often over the combined strategy space, and thus requires the simultaneous...
متن کاملCache "Less for More" in Information-Centric Networks
Ubiquitous in-network caching is one of the key aspects of information-centric networking (ICN) which has recently received widespread research interest. In one of the key relevant proposals known as Networking Named Content (NNC), the premise is that leveraging in-network caching to store content in every node it traverses along the delivery path can enhance content delivery. We question such ...
