碩士 === 國立屏東科技大學 === 資訊管理系所 === 96 === The wireless communication has experienced significant changes in the recent past and it will continue to evolve in the foreseeable future. Sensor network is a hot and popular research field in the wireless networks nowadays. Routing protocol is a critical research topic. Recently, a very successful framework named AIMRP (Address-Light Integrated MAC and Routing Protocol) regarding routing protocol in sensor network is proposed. Basically, the AIMRP can employ fewer routes than the other schemes and may obtain test responses very quickly. However, the AIMRP may generate the response on several nodes and must establish several routes individually. Moreover, it may confront with the problem of data burst. To solve this problem, this thesis presents a new cluster-based optimum design of routing protocol based on AIMRP named C-AIMRP. The proposed C-AIMRP algorithm has the advantages of AIMRP and cluster-based routing protocol in wireless sensor networks. According to the simulation results, the proposed routing protocol of C-AIMRP outperforms the existing well-known approaches, such as TTDD and AIMRP in energy consumption comparison for wireless sensor network.
