To achieve the proper management of WSN and for its limited resources is highly desirable for an effective and efficient functioning of the network, we propose a low overhead, hierarchical wireless sensor network management architecture. The proposed mechanism provides the methods to monitor the network states by collecting management data and accordingly control and maintain the network resources...
Due to the dynamic and anonymous nature of open environments, it is critically important for agents to identify trustful cooperators which work consistently as they claim. In the e-services and e-commerce communities, trust and reputation systems are applied broadly as one kind of decision support systems, and aim to cope with the consistency problems caused by uncertain trust relationships. However,...
In this paper, we introduce an m-commerce security architecture; discuss how the communication takes place between user, mobile station (MS) and access point (AP). We use an new authenticated mechanism between user and MS. And we add Access Point in wireless net in order to avoid being attack and eavesdropping message. We analyze the characters of the architecture with the Summary of Mobile E-commerce...
Inspired by the principles of biological immune system, an antibody concentration based method for network security situation awareness, referred to as ACnssa, is proposed in this paper. With the concepts and formal definitions of self, non-self, antibody and antigen presented, the principles and framework of ACnssa is described. Following that, the mathematical models of the lifecycle of mature and...
A systematic scheme to form the watershed computational platform was developed based on lightweight Grid technique in this paper. The scheme that takes advantage of widely deployed local network makes full use of the non dedicated distributed computing resources. To overcome the vagary of overall system, MPICH-T a trust model based fault tolerant model was adopted, and the checkpoint based on pessimistic...
