Stop and don’t move

Signatures dont des falsifications sont prouvables , et leur application – – – – – – – – Fail - stop Signatures and their Application

The unforgeability of conventional digital signatures is necessarily based on complexity theoretic assumptions, i.e. even the most secure schemes can be broken by an adversary with unexpected computing abilities. Thus we introduce fail-stop signatures: They are as unforgeable as the best conventional signatures, but if a signature is forged nevertheless, the supposed signer can prove the forger...

A Stop-or-Move Mobility model for PCS networks and its location-tracking strategies

This paper considers the location-tracking problem in PCS networks. Solutions to this problem in fact highly depend on the mobility patterns of mobile subscribers [ACM DIAL-M (1999) 72]. In the literature, many works have assumed a simple random walk model, where mobile subscribers always stay in a roaming state and can move in any direction with equal probability. In this paper, we propose a n...

Analyzing the Mobility and Protocol Performance in MANET using a Novel Move Stop Deviate Model

In this work, we have designed and implemented a novel Move Stop Deviate mobility model for Mobile ad hoc networks. In the MSD mobility Model, the node travels randomly for a total of 20 units before changing its direction, stops for a certain amount of time. Then it deviates angular direction (between angle 0, 45, 90, 135, 180, 225, 270, 315 only) and moves further. As soon as the boundary is ...
