A revised Mint-Route protocol in wireless sensor networks

摘要

The Mint-Route routing protocol was proposed to enhance reliability by choosing adjacent link with the smallest number of lost packets as next hop in wireless sensor networks. However, since packets are transmitted over unstable wireless link, physical distance between nodes can mostly affect the reliability. So, long path with many hops is usually established between source and destination while considering current metrics. To solve this problem, we develop a revised Mint-Route protocol by considering the received packet as well as distance together while deciding parent node toward the sink. Simulations and their analysis are followed to validate the suitability of reduced end-to-end delay and enhanced reliability.
