Non-uniform distribution node scheduling scheme in wireless sensor networks

Aiming at the defect that high computational complexity of exact location information and the distribution limitation of location information-free in traditional schemes,the node distribution was analyzed theoretically.A node scheduling scheme NDNS(non-uniform distribution node scheduling) was proposed which satisfies with different ran-dom distribution.The precision for node redundancy evaluating was improved by using the distance information between the sensor and its neighbors and applicable to any distribution deployment.The scheme was analyzed and validated for performance through experiments.The numerical experiments results illustrate that the longer network lifetime was achieved in preserving networks coverage.
