Distance vector hop（ DV-Hop） improved algorithm

spring coefficient and RSSI DV-Hop（ SCRDH）localization algorithm based on spring coefficient and received signal strength indication is proposed. The algorithm abstracts the shortest path between nodes and anchor nodes into spring model

and uses the spring model to improve dereferencing method of DV-Hop whole network average hop distance and minimum number of hops between nodes

and also improve the positioning precision by increasing coefficient of spring of whole network.Simulation results show the localization error of SCRDH algorithm can reach 12 % under certain conditions

which is prior to DV-Hop algorithm.
