In a random deployment, sensor nodes are scattered randomly in the sensing field.Hence, the coverage can chocolate chip cookie purse not be guaranteed.In contrast, the coverage of uniformly deployment is in general larger than the random deployment.

However, uniformly deployment strategy may cause unbalanced traffic pattern in wireless sensor networks (WSNs).In this situation, larger load may be imposed to CHs (cluster heads) around the sink.Therefore, CHs close to the sink use up their energy earlier than those farther away from the sink.

To overcome this problem, we propose a novel node deployment strategy in the concentric el reformador tequila anejo model, namely, Region-based Intelligent Cluster-Head selection and node deployment strategy (called Rich).The coverage, energy consumption and data routing issues are well investigated and taken into consideration in the proposed Rich scheme.The simulation results show that the proposed Rich alleviates the unbalanced traffic pattern significantly, prolongs network lifetime and achieves satisfactory coverage ratio.
