Privacy is needed in ad hoc networks. In order to provide anonymous routing protocol in MANETs the location of source and destination can be concealed by using “notify and go” mechanism and broadcasting. In this paper, we address some of the issues arising in MANETs by using an anonymous routing protocol. Location Based Anonymous Routing Protocol partitions the network into zones for anonymity ...

this solution has a flaw which in certain circumstances allows the malicious construction of apparently authentic messages. Finally note that it is not the intention of the author to criticise what is after all only an RFC,l but rather to ensure that possible solutions to multi-destination secure message authentication problems are analysed with care. There are many lessons to be learnt from th...

A two stage approach to travel destination choice was developed based on the construct of an evoked set. The two stages were evolution of an evoked set from the awareness set; and destination selection from the evoked set. It was hypothesized at both stages that travel destination choice depends upon attitude toward each alternative. Attitude was operationalized as the difference between percei...

The problem addressed here is the guidance of a mobile robot within an unknown indoor environment, and in particular mapping. Although much success has been reported using laser scanners for this task, the use of vision-based sensing presents both problems and advantages. The revisiting problem in mapping is addressed by using the Consistent Pose Estimation algorithm.

The aim of these lecture notes is a description of the statics and dynamics of zero-range processes and related models. After revisiting some conceptual aspects of the subject, emphasis is then put on the study of the class of zero-range processes for which a condensation transition arises. From urn models to zero-range processes: statics and dynamics 2 Introduction

Recent developments in the theory of 3-manifolds, centered around the Poincaré conjecture, use methods that were not envisioned by Poincaré and his contemporaries. Nevertheless, the main themes of 3-manifold topology originated in Poincaré’s time. The purpose of this article is to reveal the origins of the subject by revisiting the world of the early topologists.
