A reliable routing protocol design for wireless sensor networks

Many routing protocols have been proposed for wireless sensor networks in recent years. For some special applications, not only energy aware but link reliable is needed. Historical link status should be captured while making routing decisions. In this paper, we design a reliable link quality estimation based routing protocol (LQER), which integrates the approach of minimum hop field and (m, k). The performance of LQER is evaluated by simulation experiments to be more energy-aware, with lower loss rate and better scalability than MHFR (Z. Ma and Y. Sun, 2004) and MCR (F. Ye et al., 2001). Thus the whole network may obtain longer lifetime and better link quality
