Precise route planning needs huge amounts of trajectory data recorded in multimedia devices. The data, including each user’s location privacy, are stored as cipher text. ability to plan routes on an encrypted database is urgent necessity. In this paper, order a public while protecting we design hybrid random bloom filter (RBF) tree databases, named the (eRBF) tree, which supports pruning and se...

High-tech giants and start-ups are investing in drone technologies to provide urban air delivery service, which is expected solve the last-mile problem mitigate road traffic congestion. However, service will not scale up without proper management for drones dense environment. Currently, a range of Concepts Operations (ConOps) unmanned aircraft system (UTM) being proposed evaluated by researcher...

Environments that are divided into regions lead to hierarchical encoding of space. Such memory structures are known to systematically distort estimates of distance and direction and affect spatial priming and memory recall. Here we present two navigation experiments in virtual environments that reveal an influence of environmental regions on human route planning and navigation behaviour. Follow...

The purpose of Multi-modal Multi-criteria Personalized Route Planning (MMPRP) is to provide an optimal route between an origin-destination pair by considering weights of effective criteria in a way this route can be a combination of public and private modes of transportation. In this paper, the fuzzy analytical hierarchy process (fuzzy AHP) and the quantifier-guided ordered weighted averaging (...
