CASHnet - Cooperation and Accounting Strategy for Hybrid Networks
Attila Weyland · 2004
Introduction Multi-hop cellular networks (also called hybrid networks) increasingly attract interest in the research community. They appear to be a promising combination of the advantages of two worlds: the dynamics of mobile ad hoc networks (MANETs) and the reliability of wired cellular networks. The MANET concept o#ers advantages attractive to Internet service providers as well as to users. The network becomes dynamically expandable, the network coverage increases and the usage of available network and energy resources can be optimized. In the context of hybrid networks new possibilities to deal with the weaknesses of MANETs become available. We think that besides the security and routing issues the cooperation among nodes is of great importance. We propose a cooperation and accounting scheme, which takes into account the availability of a reliable network infrastructure and stimulates cooperation by making it a rewarding alternative to selfishness. Recently, few approaches have bee
