Multihop realization and routing optimization of WPAN

First discusses about some characteristics of WPAN compared with the traditional networks, from the view of the realization optimization of multimedia communication network in wireless small area. Especially analyzes the multihop realization and routing optimization of WPAN, detailed explains the potential superiorities, principles, function mechanisms of DSR, proposes the realization methods, gives and analyzes the concrete measures from five aspects such as conforming route length, limiting multiple hops and so on. Then simulates this routing protocol. The simulation results show that the realization methods and concrete measures of DSR of this paper have distinct advantages. They have been applied in the design and manufacture of WPAN system based on Bluetooth technique.
