The challenges of wireless and mobile computing environments have attracted the attention of researchers to revisit the conventional implementation of distributed computing paradigms. In this paper we propose to revisit the conventional implementation of the Two Phase Commit (2PC) protocol which is a fundamental asset of transactional technology for(More)
The tracking allows to detect the tumor affections of cervical cancer, it is particularly complex and consuming time, because it consists in seeking some abnormal cells among a cluster of normal cells. In this paper, we present our proposed computer system for helping the doctors in tracking the cervical cancer. Knowing that the diagnosis of the malignancy(More)
Recently, advances in mobile computing development have renewed the interest in the transaction techniques, in particular atomic commit protocols (ACPs). In this study, we propose a simulation platform for mobile distributed transaction systems and use it to compare the performances of a set of mobile ACPs. The results demonstrate the necessity of(More)
layer signalling protocol, SIP offers mobility management capability. However SIP Terminal Mobility suffers from considerable handoff latency which is unsuitable for real time applications and frequent local movements (intra domain handoffs). Hierarchical Mobile SIP (HMSIP) was then proposed as a solution to reduce the SIP handoff delay and to provide a(More)
Disaster management and risk prevention in Algeria have undergone many changes in the recent years. Important efforts have been provided on the legal and organizational sides to set the right conditions for an integrated and collaborative framework for disaster management in the country. The aim is to address the lack of information sharing, coordination(More)
more than a decade, many proposals and standards have been designed to deal with the mobility issues; however, there are still some serious limitations in basing solutions on them. In this paper we discuss the possibility of handling mobility at the application layer. We do this while revisiting the conventional implementation of the Two Phase Commit (2PC)(More)
Association rules mining (ARM) is a well-known combinatorial optimization problem aiming at extracting relevant rules from given large-scale datasets. According to the state of the art, the bio-inspired methods proved their efficiency by generating acceptable solutions in a reasonable time when dealing with small and medium size instances. Unfortunately, to(More)
