This paper proposes a new location problem of competitive facilities, e.g. shops. In the most studies of competitive facility location, the distance between the facilities and their customers is represented as the Euclid distance. The proposing location problem introduces the A-distance, proposed by Widmayer etc., for representing the situation that the directions which customers can move are g...

Location-Routing Problem (LRP) can model several life situations. In this paper we study The Capacitated Location Routing Problem (CLRP) which is defined as a combination of two problems: the Facility Location Problem (FLP) and the Vehicle Routing problem (VRP). We propose a twophase approach to solve the CLRP. The approach is based on Simulated Annealing algorithm (SA) and Ant Colony System (A...

By using position information in forwarding decisions, location based routing protocols for mobile networks are stateless and efficient. However, they are heavily dependent on location services which provide the position information of the desired destination node. Although several location service schemes have been proposed, their main goal is just to find the location of the destination node....

We consider the characteristics of automatic warehousing systems with irregular positions, in order to improve the optimization control objectives of the overall working efficiency and space utilization, this paper studies the irregular storage optimization distribution strategy, presents the mathematical model to optimize the irregular storage area and each storage location, and then two-level...

Object databases have gained much interest due to the advances in mobile communications and positioning technologies. To provide security to moving object need monitoring . Monitoring moving objects have two fundamentals issues like efficiency and privacy. This paper proposes an efficient algorithm for finding good anonymization group for given objects (MOB) with respect to its Quasi-Identifier...

Location-based Services (LBS) have become a very important area for research with the rapid development of Internet of Things (IoT) technology and the ubiquitous use of smartphones and social networks in our daily lives. Although users can enjoy a lot of flexibility and conveniences from the LBS with IoT, they may also lose their privacy. Untrusted or malicious LBS servers with all users’ infor...

This paper proposes a mobility model and a neural location predictor (NLP) to predict the location of a mobile host (MH). The seemingly random movement is actually a logical function of the user’s position, speed, acceleration and direction. (x,y) of a coordinate should be treated independently such that NLP can be designed with fewer mathematic operations and achieves high computing efficiency...
