We investigate the impact of mobility on energy consumption in mobile Ad hoc networks in this paper. Considering a cell-partitioned model of a delay-tolerant mobile ad hoc network with Markovian mobility, we focus on that the communication only occurs in the same cell or the adjacent cell. In this model, we characterize the mobility which have an influence on energy consumption as the nodes' maximum...
In a Mobile-CDN, Base Stations (BSs) are equipped with storages for replicating content, and they are allowed to cooperate in replying user requests through backhaul links. In this paper, we investigate the joint optimization problem of content placement and user request redirection for such a BS-based mobile CDN system. Specifically, each BS maintains a transmission queue for replying user requests...
In the absence of end-to-end paths and without the knowledge of the whole network, packet forwarding, including forwarding decision (i.e., forwarding or dropping the packet) and relaying selection, is crucial to be made by the individual of the node based on the packet-forwarding protocol in autonomous mobile social networks (MSNs). In this paper, we investigate the adaptive packet forwarding in MSNs...
The development of Network Function Virtualization (NFV) and Software Defined Networks (SDN) standards is an opportunity for Mobile Network Operators (MNOs) to deploy Content Delivery Network (CDN) functionalities into the mobile network edge, such as Base Stations (BSs). In this paper, we investigated the content placement problem for the BS-based wireless CDN system. We call the storage resources...
In this paper, we investigate the data diffusion for mobile wireless networks using percolation theoretic approaches. By considering the impacts of both node mobility and the willingness of node for the message on the data diffusion probability, we employ a one-dependent percolation model to characterize and analyze the diffusion of data on a general directed and locally finite graph. To model the...
