Abstract
In order to keep up with new networking needs, it is necessary to
adopt mechanisms for charging network usage in a universal way. The
Secure Charging Protocol (SCP) aims at answering this complex authentication,
authorization, accounting and charging (AAAC) problem. SCP fits business
models especially adequate for ad-hoc networks. This document discusses
SCP as a possible solution to the AAAC problems in MANETs and presents
the improvements made to this protocol in terms of Quality of Service
(QoS). An implementation of this protocol on PDAs and the results
achieved are discussed.
