Long Transmission Range Performance Evaluation on RI-MAC protocol in Wireless Sensor Networks

Abstract: In this paper, we are evaluating the performance receiver-initiated MAC (RI-MAC) protocol in long transmission range application focuses on the extended transmission range from 250m to 850m in wireless sensor nodes(WSN) using computer simulation. The reason to extend the transmission range is to apply the WSN in wider coverage with lower node density to achieve cost effectiveness, such as in the random networks. From the results obtained, that the maximum transmission range of WSN is less than 650m. The significant of this paper is to highlight the limitation of the current protocol when transmission range is extended to 850m, hence justifying the need to enhance the existing protocol for long transmission range application in WSN.
