Agent Mobility Model based on Street Centrality
نویسنده
چکیده
Current agent mobility models are based on random movement. This means that the probability that a particular agent will be at a particular place is the same over the whole network. In contrast, we are trying to simulate an agent movement that reflects more realistically the distribution of vehicles in an urban street network. This can be achieved by moving away from the problem of an equal probability to a more unequal probability that is based on betweenness centrality, such that agents have a definite preference to traveling on a particular path.

A Formal Petri Net Based Model for Antivirus Update Agent System
In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...

متن کاملAgent-based simulation of human movement shaped by the underlying street structure
Relying on random and purposive moving agents, we simulated human movement in large street networks. We found that aggregate flow, assigned to individual streets, is mainly shaped by the underlying street structure, and that human moving behavior (either random or purposive) has little effect on the aggregate flow. This finding implies that given a street network, the movement patterns generate...
متن کاملStudying spatial effects on human mobility patterns using agent-based simulations
1. Random and goal oriented walk models To simulate human movement in a street network, we setup some random walkers which can hop from one street to another arbitrarily. The hopping behaviour is defined at a topological level in which individual streets are represented as nodes and street intersections as links of a connectivity graph (Figure 1). On the other hand, the simulation has yet to be...
متن کاملUnderstanding urban traffi c-fl ow characteristics: a rethinking of betweenness centrality
In this study we estimate urban traffi c fl ow using GPS-enabled taxi trajectory data in Qingdao, China, and examine the capability of the betweenness centrality of the street network to predict traffi c fl ow. The results show that betweenness centrality is not a good predictor variable for urban traffi c fl ow, which has, theoretically, been pointed out in existing literature. With a critique...
