— In this paper, we consider the problem of providing efficient resiliency for data centric storage in wireless sensor networks, which is recently gaining interest. Three types of canonical storage methods are available in the literature for storing the sensed data, namely, external storage, local storage, and data centric storage. In these methods, a(More)
Previous works have proposed analytical models of TDM wavelength networks to evaluate the blocking performance, but they differ in their underlying assumptions and have varying computation complexities. In this paper, we propose an analytical model of TDM WDM optical networks with optical time-slot interchangers and without wavelength converter for minimum(More)
Virtual enterprise provides an attractive model for autonomous healthcare organizations to synergize and leverage the strengths of each others. We present in this paper the design concept and working principle of an inter-organizational workflow process management system for virtual healthcare enterprises. We propose an extended WFMC process Meta model and(More)
