A Mobile Ad Hoc Network (MANET) adopts a decentralized communication architecture which relies on cooperation among nodes at each layer of the protocol stack. Its reliance on cooperation for success and survival makes the ad hoc network particularly sensitive to variations in node behavior. Specifically, for functions such as routing, nodes which are limited in their resources may be unwilling ...

Information systems have always been in a prime focus in organizations in both local (Pakistani) and global environment. Now the race of being the best through Information Systems has created its importance in public sector organizations to meet the global challenges. Public sector organizations have been facing problems in different segments of technology adoption especially in ERP projects. E...

In order to progress in the present-day complex and unpredictable environment, the company must feature abilities of quick response and favorably reposition itself on the market. Acquisition and preservation of this capacity is the most difficult step for companies as it involves many endogenous and exogenous factors and the process is continuous, dynamic and hardly predictable. In this context...

Protection of users’ privacy has been a central issue for location-based services (LBSs). In this paper, we classify two kinds of privacy protection requirements in LBS: location anonymity and identifier anonymity. While the location cloaking technique under the k-anonymity model can provide a good protection of users’ privacy, it reduces the resolution of location information and, hence, may d...

ADSlraCI: 1rns paper aoaresses roDUSIcomroi OJ mumpre mobile robots moving in desired formations. A rigorous control technique for such an agent-based robotic system may encounter problems of singularity, parameter sensitivity and inter-robot collision. Our proposed approach focuses on the enhancement of robustness as well as collision-free establishment of formations even in the case of singul...

The second edition of the contest on Multi-Agent Systems based on computational logic was held in conjunction with the CLIMA ’06 workshop in Hakodate, Japan. Based on the experiences from the first edition of this contest ([8]), we decided to improve the setting of the first edition. In particular, we built a server to simulate the multi-agent system environment in which the agents from differe...

Weighted voting games provide a popular model of decision making in multiagent systems. Such games are described by a set of players, a list of players’ weights, and a quota; a coalition of the players is said to be winning if the total weight of its members meets or exceeds the quota. The power of a player in such games is traditionally identified with her Shapley– Shubik index or her Banzhaf ...

With the development of real time localization and mobile computing technology, it becomes increasingly popular for sharing individual locations in mobile online social network (mOSN), which inevitably raises significant concerns on the privacy of users’ locations. Recently, Wei et al. provided the MobiShare mechanism to enable flexible location sharing between both trusted social relations and...

The design of a problem solver for a particular problem depends on the problem type, the system resources, and the application requirements, as well as the specific problem instance. The difficulty in matching a solver to a problem can be ameliorated through the use of online adaptive control of solving. In this approach, the solver or problem representation selection and parameters are defined...

Classroom environments considered to be technology rich tend to show little difference between male and female achievement outcomes in the science classroom. This study investigates the effects of internet-based chemistry simulations viewed through the lens of gender in a high school chemistry classroom. This study examines 201 students enrolled in a chemistry class nested in an urban high scho...
