Research on Routing Protocol of Wireless Ad Hoc Network Based on Wearable Computers

Wearable computers need networking by using wireless ad hoc network in order to utilize them more effectively, routing protocol becomes an important research field for its significance in wireless ad hoc network. In Ad Hoc network, there are mainly two kinds of routing protocols: proactive routing protocol and on-demand routing protocol, to evaluate the performance of two kinds of protocols, we choose two representative protocols, DSDV and AODV, and implement network simulations with OPNET. Packet delivery ratio, average end-to-end delay and energy consumption are analyzed and compared by changing node¿s speed, the interval of sending packet and initial energy. Simulation results demonstrate that on-demand routing protocol is suitable for the wearable computer network where energy supply is limited, topology changes a lot or communications frequently, and proactive routing protocol is suitable for the wearable computer network where high real time is required.
