Abstract |

|
| Outstanding features such as low-rate and short-range wireless radio communication on a small device often hamper high reliability in wireless sensor networks. Despite of these constraints, high reliability becomes one of the essential requirements since it is highly demanded by more and more network services. To meet this requirement, various approaches have been proposed in each layer. Among those, MintRoute is a well-known network layer approach that develops a new metric based on link quality for selecting path towards the sink. By choosing a link with the highest measured value, the possibility to transmit packets without error becomes high. However, there are still several issues to be mentioned during operations. In this paper, we focus on network stability in MintRoute. We analyze different features which make MintRoute unstable and propose the revised algorithm by developing new metric together with adjusting parent selection procedure at different scenarios. Simulation results and analysis validate the suitability of stabilized time to enhance the reliability of communication. |
