Optimal gradient routing with two-hop information for industrial sensor networks

This paper studies gradient routing with two-hop information for industrial wireless sensor network to enhance real-time performance with energy efficiency. The two-hop information routing is adopted as that in two-hop velocity based routing and the proposed routing algorithm is based on the number of hops to sink instead of distance. Furthermore, an acknowledgement control scheme reduces energy consumption and computational complexity. The simulation results show performance enhancements regarding to delay and energy efficiency.
