Force reflection methods are widely used in teleoperation with force sensors on slave manipulator. However, force sensors would impair manipulator structure and may be installed or maintained difficultly on slave site. Additionally, in some tasks operator pays more attention to control the exerted force on environment than to fell the reflection force. Considering these factors, a force sending method is proposed in this paper with force sensors installed only on master manipulator. Adjusted virtual force is provided to operator on master site. Operator force sending and slave manipulator position tracking are achieved without conflict on slave site. Stability analysis is presented based on ISS(input-to-state stability) method and numerical simulations are given to show the effectiveness.

Special Re-use TDMA(STDMA) emerges as a promising channel access technique for providing Quality of Service(QoS) guarantees in multi-hop ad Hoc networks such as community mesh and sensor networks. The contention-free channel access combined with special reuse of the channel provides significant benefits in the energy/throughput trade-off. However, the protocol may introduce scheduling delay if, on the same path, an outbound link on a router is scheduled to transmit before an inbound link on that router. The total scheduling delay can be quite large since it accumulates at every hop on a path. This paper presents a method to solve this problem to improve the performance of the network system. Compared to the origin STDMA protocol, simulation results present us the superior performance of the proposed algorithm.
