A relaying bandwidth reservation approach for the data oriented transmission service

In this paper, a novel wireless relay algorithm is proposed to support newly appeared data flow. The relay node is integrated with new data forwarding capability. The most widely applied wireless sensor network is introduced with IEEE 802.15.4 which is a common lower layer of WIA and ZigBee. The bandwidth is reserved through the broadcasting beacon and direct diffusion approach. All the data flow is sent with low power mode; the advantage of proposed approach is not obvious compared with traditional approach. However, the reserved bandwidth ratio can be modified to improve the performance. It is verified in the simulation platform and can be applied in the future network.
