Abstract:To deploy sensor nodes over the area of interest, a scheme, named node scattering manipulation, was proposed. It adopted the following method: during node scattering, the initial states of every node, including the velocity and direction, were manipulated so that it would land in a region with a certain probability; every sensor was relocated in order to improve the coverage and connectivity. Simultaneously, to easily analyze the process of scattering sensors, a trajectory model was also proposed. Integrating node scattering manipulation with trajectory model, the node deployment in wireless sensor network was thoroughly renovated, that is, this scheme can scatter sensors. In practice, the scheme was operable compared with the previous achievements. The simulation results demonstrate the superiority and feasibility of the scheme, and also show that the energy consumption for sensors relocation is reduced.

 

Key words: wireless sensor network; node scattering manipulation; trajectory model; energy consumption
