Channel interference and node mobility cause significant performance degradation to wireless networks. In multichannel multi-flow mobile cognitive ad hoc networks, it becomes even worse due to both unexpected primary user activities and potential interference among multiple flows. In this paper, we propose a Joint Routing and Channel Assignment (JRCA) approach based on delay prediction. Firstly, it...
We address the route optimization problem for a nested mobile IPv6 NEtwork MObility (NEMO) environment. We propose an adaptive scheme which can optimize the routing process of the data communication, and minimize the end-to-end delay. The adaptive scheme consists of two sub-schemes: mobility-transparency sub-scheme and time-saving sub-scheme. The mobility-transparency sub-scheme performs well for...
One major obstacle stunting the development and application of mobile ad hoc networks (MANETs) is the lack of a thorough understanding on the throughput capacity of these networks. Preliminary works regarding the exact capacity study of MANETs mainly focus on cell-partitioned networks, an oversimplified network model for practical MANETs. This paper studies the exact throughput capacity under a more...
A wireless ad hoc network (WANET) is a collection of wireless terminals that communicate with each other without predetermined topology. Since WANET devices are power-limited, network protocols should be designed to prolong the battery lifetime of these devices. In this paper, we propose a cross-layer integration approach for power efficient routing protocol. The proposed cross-layer integration between...
In mobile ad hoc networks nodes should collaborate with each other to support the functions of the network. The trust management framework, which evaluates the trust of participating nodes, is used to force nodes to cooperate in a normal way. We make an effort to design a robust and attack-resistant trust management framework for the future. In this article we describe the vulnerabilities of and possible...
