蓝牙散射网可以通过将两个或多个微微网互连在一起来形成。为了减少主节点和桥节点的业务负载，提出了两阶段散射网形成（TPSF）算法（Kawamoto，Y.例如，IEEE WCNC '03，2003）。为控制分组的传输创建控制分散网。对于每个源和目的地对，创建按需散射网以用于数据分组的传输。原始的TPSF没有考虑节点移动性的支持。我们提出了TPSF+，这是一个扩展的按需分散网形成在原来的TPSF。在TPSF+中，当两个节点之间需要通信会话时发现路由信息。仿真结果表明，与原TPSF相比，TPSF+具有更高的路径连接成功率。与BTCP相比，所提出的TPSF+还具有更高的总吞吐量和更小的端到端延迟（Salonavirt，T.例如，Proc. IEEE INFOCOM'01，2001）和Bluenet（Wang，Z.例如，Proc.35th夏威夷Int. Conf. on System Sciences -Proc. SS-35，2002）。
A Bluetooth scatternet can be formed by interconnecting two or more piconets together. To reduce the traffic load of master and bridge nodes, a two-phase scatternet formation (TPSF) algorithm was proposed (Kawamoto, Y. et al., Proc. IEEE WCNC '03, 2003). A control scatternet is created for the transmission of control packets. For each source and destination pair, an on-demand scatternet is created for the transmission of data packets. The original TPSF does not consider the support of node mobility. We propose TPSF+, which is an extension of the on-demand scatternet formation in the original TPSF. In TPSF+, route information is discovered when a communication session is required between the two nodes. Simulation results show that TPSF+ has a higher successful path connection ratio when compare with the original TPSF. The proposed TPSF+ also has a higher aggregate throughput and smaller end-to-end delay when compared with BTCP (Salonidis, T. et al., Proc. IEEE INFOCOM'01, 2001) and Bluenet (Wang, Z. et al., Proc. 35th Hawaii Int. Conf. on System Sciences - HICSS-35, 2002).
