In Delay Tolerant Networks (DTNs), information search is an important topic, which has not been widely investigated yet. Recently, pervasive and ubiquitous computing scenarios are pushing situations where it is the recipient (instead of the sender) who determines whether and how to seize data flowing in the network. Most existing information search schemes(More)
In mobile social networks (MSNets), data dissemination is an important topic, which has not been widely investigated yet. Active data dissemination is a networking paradigm where a superuser intentionally facilitates the connectivity in the network. One of the key challenges under this paradigm is how to design the most efficient superuser route to achieve(More)
Complex industrial processes are controlled by the local regulation controllers at the field level, and the setpoints for the regulation are usually made by manual decomposition of the overall economic objective according to the operators' experience. If a precise static process model can be built, real-time optimization (RTO) can be used to generate the(More)
In this paper, we consider the issue of data broadcasting in mobile social networks (MSNets). The objective is to broadcast data from a superuser to other users in the network. There are two main challenges under this paradigm, namely 1) how to represent and characterize user mobility in realistic MSNets; 2) given the knowledge of regular users' movements,(More)
This paper investigates the setpoints compensation for a class of complex industrial processes. Plants at the device layer are controlled by the local regulation controllers, and a multirate output feedback control approach for setpoints compensation is proposed such that the local plants can reach the dynamically changed setpoints and the given economic(More)
Mobility pattern of device users plays a crucial role in a wide range of mobile computing applications, including data forwarding, content sharing, information search and advertising. Hence, it is important to characterize the mobility path information of users, so as to accurately predict user mobility. In this paper, we introduce two typical user mobility(More)
Several simulation tools are used to evaluate network performance including OMNeT++. In this paper, a case of topology control (TC) in WSNs is simulated by considering its interaction with MAC layer and routing based on the SensorSimulator framework. Some ways to improve the simulation efficiency are described. Finally, the simulation results are given.
