OBJECTIVE: To propose a conceptual framework that supports the identification of the level of adherence of software projects regarding ubiquitous computing METHOD: To run systematic reviews to characterize 1) ubiquitous computing, 2) its main features and 3) its specific requirements RESULTS: Fifty seven papers were analyzed regarding: (1) the ubiquitous computing definition, (2) ubiquitous applications, and, (3) 10 dimensions characterizing ubiquitous applications To complement these results, other systematic review was accomplished In this case, fifty nine papers were analyzed identifying a set of 123 functional and 45 nonfunctional requirements associated to the ubiquitous dimensions CONCLUSIONS: It is possible to have a common perspective to work with the ubiquitous software engineering area including the definition for ubiquitous computing and ubiquitous dimensions, and functional and non-functional requirements associated to each ubiquitous dimension Therefore, a conceptual framework to classify software projects according to the adherence to the ubiquity perspective has been organized and discussed in this work.

The Broadband Wireless Access (BWA) technology has been proposed to support different traffic classes with distinct quality of service (QoS) requirements in broadband metropolitan area networks. Therefore, as part of its specifications, such a system must properly address the combined requirements of wireless communications and multimedia applications. We propose in this paper an extension to the MAC protocol presented in [1, 2], by assigning variable priorities to the network stations sharing access to the communication channel. An analytical model to evaluate the performance of the proposed protocol is also developed and results obtained for the messages waiting times at different stations are presented. In addition, simulation data are used to compare the results obtained from the analytical model presented previously. It is concluded that the proposed variable priority MAC protocol is able to improve channel utilization and provide throughput and queueing delay fairness among the stations in the network.

We present the use of the polysaccharide chitosan for immobilizing biomolecules on microfabricated device surfaces. The main advantages of chitosan are its abundance of primary amine groups and its ability to be electrodeposited. Biomolecules are easily attached to chitosan 's amines by standard glutaraldehyde chemistry. The electrodeposition of chitosan allows accurate spatial and temporal control of biomolecule placement. We have demonstrated this biofunctionalization method for two different bioMEMS devices: a biophotonic sensor and a micromechanical biosensor. We have successfully assembled probe DNA on each of them and detected hybridization with target DNA as a demonstration of sensor operation. Here, we briefly present the fabrication procedure and testing results for both of these bioMEMS sensing devices
