Design principles and performance for flooding routing mesh topology spread spectrum LANs

This paper presents a family of mesh topology LANs that uses spread spectrum techniques as a method for media access control so as to offer (1) the possibility of simultaneous access to the network, and (2) to provide similar performance to all communication channels while reducing the probability of any collision. For routing, flooding algorithms are proposed. The proposed architecture is characterized by survivability, security and relatively low bandwidth requirements. A LAN member of this family is also analysed. It is built on a topology that consists of a set of inter-communicating sub-LANs and interconnected subgraphs. The topology, the communication and the signalling protocols that support this architecture are presented. Parameters influencing the traffic load of such a LAN are examined, and estimates of the bit error rate (BER) as a function of the parameters are presented.
