Current surveillance system in some specific places like bank, hospital or train station are not efficient enough for city manager or policeman. Huge amount of manpower are needed to make full use of these surveillance data in crime research. In this paper, a novel highly automated surveillance system are proposed. The system would get the identification information and human position indirectly by...
We introduced the concept of a community-based social recipe system which suggests recipes to groups of users based on available ingredients from these users (i.e. who can be from the same household or different households). In this paper we discuss the relevance and desirability of such a system and how it should be designed based on user studies. We identified the relevance of targeting ingredients...
Food waste has received little attention in pervasive computing. In this paper we discuss previous work which stresses the need for understanding how intelligent technology could prevent food waste in households. We present EUPHORIA, a community based social system that can track users' food waste potential and redirect behavior, through social influence strategies, towards more sustainable food related...
The emergence of Cloud Services and Mobile Internet has influenced the society a lot, including the tourism industry. This paper proposes a design of backpacking service, not only aimed at the travelling routines, but also focus on the low-cost airlines. This kind of service aids backpackers with an effective travelling and satisfy the price requirement. With this low-cost airlines system, the backpackers...
This paper firstly proposes a new algorithm for finger touch detection based on front-projected vision-based table system. The algorithm, taking advantage of shadow information, can locate possible finger touch with low complexity. An adaptive structured light method is introduced to improve the precision of touch detection effectively. Secondly, we present a new prototype system architecture and...
Flooding mechanism is widely used in ad hoc networks for its high reliability and coverage rate. However, flooding is inefficient for its large number of redundant messages and extortionate energy consumption. To support rapid route discovery without introducing too much route discovery traffic, an on-demand routing protocol for mobile wireless ad hoc networks, called Selection Forward Routing (SFR),...
In this paper, a novel OFDM symbol timing recovery method, which is robust to doubly selective fading channels and carrier frequency offset, is proposed for the mobile terminals of CMMB system. The time slot timing synchronization is accomplished by using the inverse sliding correlation between the segmenting Sync sequences, which possess the inverse conjugate symmetry (ICS) characteristic. Furthermore,...
Group mobility in WSN is of particular importance as it is can be found in many practical application scenarios. In this paper, we propose to combine HIP and NEMO protocol for supporting group mobility in WSN. The overview of HIP and NEMO protocol is introduced and the new network architecture for applying HIP and NEMO protocol in WSN is proposed, which enhances mobility management, network security...
One of the performance issues that has come to light upon study of field data from deployed GSM networks is the occurrence of call-drop due to slow handoff since the reverse link messages can not be delivered to the mobile terminal. It is hard to develop an accurate mathematical model for call-drop. In this paper, A new way is recommended by combining the fuzzy case-based reasoning (CBR) with the...
