Abstract |
|
|
| Localization is crucial to many applications in wireless sensor networks (WSN). In some
applications, all nodes are constantly moving in the network. The current algorithms do not
appropriately address the problem of enabling nodes of mobile wireless sensor networks (MWSN) to
determine their locations. To solve this problem, a new range-free localization algorithm (SSML)
based on the idea of sector scan for MWSN is proposed. By using sector scan, the proposed algorithm
minimizes the overlapping areas determining the location of the unknown nodes. Therefore, the
localization accuracy can be improved. The simulation results shows that SSML algorithm can
obviously improve the localization accuracy compared with Convex and Monte Carlo Localization
(MCL), and the accuracy of the SSML is lower than 10%. |
