One of the most important objectives of a wireless network is to facilitate a prediction of users mobility regardless of their point of attachment to the network. In indoor environments the effective users motion prediction system and wireless localization technology play an important role in all aspects of peoples daily lives. In this paper we propose an activity-based continuous-time Markov model to define and predict the human movement patterns. This model is a simple extension of an Activity based Mobility Prediction algorithm using Markov modeling (AMPuMM) technique. Both models are experimentally evaluated in realistic small university campus scenario. The obtained results show us the high efficiency of the jump methodology in the prediction of the students activities in the indoor campus environment.

Software-as-as-Service (SaaS) is a new approach for developing software, and it is characterized by its multi-tenancy architecture and its ability to provide flexible customization to individual tenant. However, the multi-tenancy architecture and customization requirements have brought up new issues in software, such as database design, database partition, scalability, recovery, and continuous testing. This paper proposes a hybrid test database design to support SaaS customization with two-layer database partitioning. The database is further extended with a new built-in redundancy with ontology so that the SaaS can recover from ontology, data or metadata failures. Furthermore, constraints in metadata can be used either as test cases or policies to support SaaS continuous testing and policy enforcement.

Software as a Service (SaaS) with multi-tenancy architecture is a popular approach. To support a significant number of tenants, SaaS applications need be customizable to fulfill the various functional and quality requirements of individual tenants. This paper presents a unified and innovative multi-layered customization framework, to support and manage the variability of SaaS applications and tenants-specific requirements. Ontology is used to derive customization and deployment information for tenants cross layers. This framework also has an intelligent recommendation engine to support new tenants to deploy using information from existing deployed SaaS applications. A case study in mortgage application is used to demonstrate the proposed model.
