,Kriterien für den Erfolg der Bio?konomie,Each node in the network pledges to help its neighbours by passing packets to and fro in return of a similar assurance from them. All is well if the participating nodes uphold such an altruistic behaviour. However, this is not always the case and often nodes are subjected to a variety of attacks by

Some works have indicated that the performance of ad hoc networks could be badly affected by Rayleigh fading channel [1]. In this paper, we identify the causes for this performance degradation and we propose a new cross-layer approach whi

In mobile wireless networks, it is desirable to transfer this context between access routers to avoid the expensive process of context re-establishment when handovers are required. In this chapter, we propose a method for avoiding the ne

Then, we describe two techniques based on a simple hash chain for an off-line authentication and its modification where one-time signatures are used for an on-line authentication. Later, we consider the TESLA scheme for authenticating

An analytical and a simulation model are presented and used to evaluate the performance of Parallel TCP. It is shown that based on these models Parallel TCP could improve TCP performan

The novelty of our model dwells on its message-based approach rather than packet based calculations, as usually found in the literature. The model matches well with those reliable multicast protocols with aggregated
