Abstract

Abstract隆陋 Position based routing methods have been used successfullyrecently for homogeneous wireless networks when all nodeshave the same transmission range, and the signal will be received byall nodes with the transmission range. All these protocols are likelyto fail for heterogeneous wireless ad hoc networks, or the signal couldbe blocked by obstacles. In this paper we assume that two nodescan always communicate directly if their distance is no more than{{\sqrt 2 } \over 2}R, where R is the maximum transmission range. A method hasbeen proposed in [1] to construct a planar topology using some virtuallinks for some routing protocols, such as [4], [9]. We present animproved method to construct another planar topology and our simulationsshow that our protocol out-performs the previous method fordense networks signicantly: it uses much less messages and createsmuch less virtual links, while the routing performances of our methodis almost the same as the previous method.
