// A network only consisting of basic modules
//
// The P2PNetwork does not contain any real functionality. It should
// be the basis for all other simulations build with our framework and
// is mainly to help to understand the concept and for all programmers
// as a reference for their own implementations. 
//
// You should use the P2PNetwork if sophisticated interference models
// are not of interest and you prefere a faster
// simulation. Collisions and interference is modeled into the bit
// error rate for these kinds of networks. The advantage is that
// interference doesn't has to be explicitly modeled and thus messages
// are not braodcasted but sent directly to the specified next hop.
//
// P2PHost is a vector of size numHosts (which specifies the number
// of hosts present in the network)
//
