Abstract

IEEE 802.15.4 is designed for low-rate wireless personal area networks. It contains two topologies: the star topology and the peer-to-peer topology. It has good performances for the star topology. However, when the beacon collides with other beacons, data or control frames make the multi-hop beacon-enabled mode difficult to be built and maintained. Although nonbeacon-enabled can handle it, it also has many disadvantages. So an improved scheme for IEEE 802.15.4 beacon-enabled multi-hop network is discussed. Extensive ns-2 simulations are used to verify the proposed scheme. The results show that the performance of the proposed scheme is much better than the performance of the previous one for beacon-enabled mode and a little better than the nonbeacon-enabled mode
