Abstract: | Networks in which each node is directly linked to its nearest neighbors exhibit high reliability and message handling capability. The construction of such networks guaranteeing minimal length, for a given degree of redundancy, is formulated in zero-one integer linear programming terms. Initial feasible solutions to the programs are presented, but connectedness is not guaranteed. In the latter case further zero-one integer programs are proposed assuring connectedness, with given initial feasible solutions. The inefficiency of zero-one programs for large networks leads to consideration of alternate redundant connected networks, without guaranteed minimal length. These networks are based on “nearest- neighbor edge sets”, and are simple to construct. Various theorems on the properties of such networks are presented with applications to one-way communicability. |
