The following topics are dealt with: network security; network privacy; computer vision; signal processing; data mining; semantic Web; network architecture protocols; network management; wireless sensor networks;and mobile ad-hoc networks.
Free-rider problem greatly influences the performance of unstructured networks (like ad-hoc or peer-to-peer networks). To solve such problem, we focus on trust management framework, which is intended to stimulate nodes to cooperate with each other. Currently, the existing trust management framework can be classified into trust establishment framework and reputation-based framework. However, none of...
Secure and efficient communication among a set of mobile node is one of the most important research subjects in ad hoc wireless networks. Due to the resource scarcity in ad hoc networks, traditional key management protocol cannot be effectively applied to such decentralized networks. After study different strategies, in this paper the trust evaluation based clustering technique is employed to propose...
This paper presents a robust key management scheme for supporting the secure communication needs of emergency response operations. The proposed scheme aims to tolerate the dynamic nature of such operations where some system and network components may be damaged or redeployed frequently. mobile ad hoc network (MANET) is widely accepted to be a suitable approach to meet the communication needs of emergency...
Ad-hoc network management differs from that carried out in networks with infrastructure in that a central node is not used to undertake tasks. Spontaneous networks may be the solution to the configuration problems posed. Here we present a distribution model to resolve these questions.
This paper presents a cluster-based self-organizing algorithm for creating automatically ad-hoc networks including diverse wireless devices such as PDA, cell phones, laptops, wireless sensors, etc. In the proposed strategy each mobile device is represented by a multi-role agent, which generates a backbone among the devices within the environment based only on local interactions. During the operation...
