Abstract All nodes in Chord can be viewed as being placed into a one-dimensional ring. In this paper, a novel concept of bi-dimensional P2P is introduced for mobile Ad hoc networks, in which nodes are placed into a square, so that more than one configurable ring can be created, and redundant lookup routes can be provided. Based on the concept, the multi-ring bi-dimensional P2P lookup protocol family is proposed. Applicable ring-configuration examples are provided and the performances are analyzed. Simulation results prove the performance improvement of the protocol family compared with Chord like protocols.
