In this paper, a simple addressing methodology called binary address scheme (BAS) is presented for the Manhattan Street Networks. It overcomes some of the deficiencies of other previously proposed schemes. It allows new nodes to be inserted into the network without changing the addresses of any existing nodes. In addition, it also reduces the computational complexity of routing. BAS provides a simple distributed routing rule that can be easily implemented by hardware in each node to achieve better performance. BAS can also be used in other networks which have strong dependence on the sequential order of node addressing.
