—This paper presents an architectural model for Wireless Peer-to-Peer (WP2P) file sharing system for ubiquitos mobile devices. File sharing is one of the rationales for computer networks with increasing demand for file sharing applications and technologies in small and large enterprise networks and on the Internet. With the popularity of mobile phones in(More)
Optimistic methods of concurrency control are gaining popularity. This is especially true with the resurgence of mobile and distributed databases during the last decade, which inherently rely on optimistic techniques to improve availability and performance of the distributed database systems. A key problem with optimistic techniques is that they do not(More)
One of the most prominent congestion avoidance schemes in the Internet architecture is the Random Early Detection (RED) algorithm. Several modifications and enhancements have been made to the original RED so as to make it more responsive to congestion avoidance at the gateways. In this paper, we introduced the Dynamic Random Early Detection (DRED) model,(More)
Existing mobility support models in cellular communications misinterpret mobility loss in cellular networks as congestion loss, thus it degrades the performance by invoking unnecessary congestion control action. In this paper, we investigated the performance of Double Buffer Technique (DBT) model for mobility support in wireless IP networks. The DBT model(More)
A digital temperature sensor is an integrated system that can sense and convert heat measurement from an analog domain to its digital equivalent. However, digital temperature sensing suffers inaccuracy as a result of shift in supply voltage. In this paper, a digital temperature sensor with an improved noise resistant technique for the reliability of digital(More)
