We analyze the ability of a stochastic coverage algorithm to achieve both accurate threat-based coverage and effective information capture. When mobile sensors are used to cover the region over time, the goal of threat-based coverage is to allocate the sensors' coverage time between the subregions in proportion to their threat levels. We show that, in contrast to prior results on mobile coverage for...
This research proposed an effective mechanism for an effective solution to tackle missing data problem in the handoff delay. The focus of this research is the effective combination of multicast-base and forecast enhancement prediction mechanism. This solution will help future network management for bandwidth reservation for mobile users in motion.
Wireless sensor network is a new information acquisition and processing technology, which is widely used in monitoring systems. Taking into account that the physical topology of the mine is relatively fixed, as well as that the energy can be added to the mobile nodes, in this paper we propose an energy-efficient wireless sensor network routing algorithm to adapt to the mine environment. Demonstrated...
With the advancement of MEMS techniques, mobile sensors with low cost and high capability are being deployed widely to carry out all kinds of complicated, risky tasks in large scale networks, especially in the areas are inaccessible to the human. Mobile sensors, which have the function of self-detection and self-repair, are desirable to solve the problem of failure of sensors, which causes costly...
In recent years, various types of ad hoc routing protocols have been studied in the mobile ad hoc networks. Specifically, the clustering hierarchical routing algorithms have been developed to increase the system performance. Hierarchical structure has inevitably brought some drawbacks, maintaining the hierarchical structure needs more complicated cluster heads selection algorithm, which may result...
Decentral recommender systems appear well suited for mobile scenarios, but have not been investigated thoroughly or implemented very much so far. We have designed and implemented a system to recommend images on personal digital assistants (PDAs). Our approach also incorporates recommending for groups of users that are present at a public shared display. The system exchanges rating vectors among PDAs,...

Mobile information services will play an important role in our future work and private life. Enabling mobility in urban and populous areas needs novel techniques for individual traffic planning. However, though there already are WAP-based traffic systems featuring route planning, their usability is not often universal. We present a SMS-based urban public traffic information system (SMS-UPTS) offering...
