Wireless Sensor Network (WSN) is a network whose energy is constrained. To efficiently use energy and enhance network viability is one of the main objectives for designing WSN. Some new concepts about the vitality of WSN are proposed, and a vitality evaluation method for WSN is studied in this paper. The analysis showed that the vitality evaluation method proposed is effective and useful.
Wireless Sensor Networks (WSNs) are susceptible to a wide range of security attacks in hostile environments due to the limited processing and energy capabilities of sensor nodes. Consequently, the use of WSNs in mission critical applications requires reliable detection and fast recovery from these attacks. While much research has been devoted to detecting security attacks, very little attention has...
Wireless sensor networks (WSNs) suffer from a wide range of security attacks due to their limited processing and energy capabilities. Their use in numerous mission critical applications, however, requires that fast recovery from such attacks be achieved. Much research has been completed on detection of security attacks, while very little attention has been paid to recovery from an attack. In this...
File transfer is very common in a modern distributed computing environment. Protocols such as HTTP and FTP are designed for downloading or uploading files from/to servers. Some other tools such as 'secure copy' are used to transfer files among hosts securely. In this paper, the file transfer is considered in the context of connecting distributed applications, what is an output of a data producer on...
It is critical to monitor the performance and "health" of large-scale peer-to-peer applications. As an example, operators of peer-to-peer live streaming applications may be interested in observing performance bottlenecks, peer failures, and network topologies. In most cases, such observations are used to diagnose potential problems in the protocol design, to troubleshoot network outage,...
