Mobile Codes Localization in Ad hoc Networks: a Comparative Study of Centralized and Distributed Approaches

Mobility and the new mode of communication used in ad hoc mobile networks cause problems proper to a mobile environment. In this paper, we study the localization problem of mobile agents in ad hoc mobile networks; an object which has a double mobility is to be located, first, in relation to the mobility of its physical support in a dynamic environment, the station, and that of the code through the network stations. A comparative study, based upon a simulation, between the localization protocols proposed in (Zafoune and Mokhtari, 2004) show that the centralized approach in a distributed form is more interesting than a totally centralized approach.
