Multihop ad hoc networks were designed assuming trustworthiness and cooperation between all participating nodes; nodes in an ad-hoc network rely on one another in packet forwarding, detecting routes, etc. Thus, the performance of an ad hoc network degrades considerably with the presence of misbehaving nodes. Nodes’ misbehaviour includes, but is not limited to, refusing to relay data packets, co...

In multipath communications of Wireless Sensor Networks (WSNs), data packets are forwarded towards the static base station (BS) through a number of paths, using a set of relay nodes. The shortest path between a source node and the destination node does not always guarantee a stable path. In this paper, a probabilistic approach for selecting energy aware stable path in WSN is proposed by which i...

In our daily lives we often have to face binary decisions where we seek to take the minority’s choice, e.g., in traffic scenarios where we have to choose between similar alternative routes. We have studied agent coordination mechanisms in a binary decision model introduced in the literature recently: the Minority Game. Extending this model, we have introduced personalities which model certain t...

This paper describes a framework for vision and motion planning for a mobile robot. The task of the robot is to reach the destination in the minimum time while it detects possible routes by vision. Since visual recognition is computationally expensive and the recognition result includes uncertainty, a trade-o must be considered between the cost of visual recognition and the e ect of information...

Although the strength of carbon nanotubes has been of great interest, their ideal value has remained elusive both experimentally and theoretically. Here, we present a comprehensive analysis of underlying atomic mechanisms and evaluate the yield strain for arbitrary nanotubes at realistic conditions. For this purpose, we combine detailed quantum mechanical computations of failure nucleation and ...

in our country, school bus routes are determined by experiments of driver without considering the scientific optimum route and location. traversing additional routes will always result an increase in vehicle movements and fuel consumption and enormous costs. hence, this paper will study the school bus routing in tehran considering special students and a model will be presented to minimize trave...

This article introduces a general framework of multi-granulation fuzzy probabilistic roughsets (MG-FPRSs) models in multi-granulation fuzzy probabilistic approximation space over twouniverses. Four types of MG-FPRSs are established, by the four different conditional probabilitiesof fuzzy event. For different constraints on parameters, we obtain four kinds of each type MG-FPRSs...

A mobile ad hoc network is collection of self configuring and adaption of wireless link between communicating devices (mobile devices) to form an arbitrary topology and multihop wireless connectivity without the use of existing infrastructure. It requires efficient dynamic routing protocol to determine the routes subsequent to a set of rules that enables two or more devices to communicate with ...

We consider distribution systems with a single depot and many retailers each of which faces external demands for a single item that occurs at a specific deterministic demand rate. All stock enters the systems through the depot where it can be stored and then picked up and distributed to the retailers by a fleet of vehicles, combining deliveries into efficient routes. We extend earlier methods f...

This paper describes ASPOGAMO, a visual tracking system that determines the coordinates and trajectories of football players in camera view based on TV broadcasts. To do so, ASPOGAMO solves a complex probabilistic estimation problem that consists of three subproblems that interact in subtle ways: the estimation of the camera direction and zoom factor, the tracking and smoothing of player routes...
