Xiaolin Lu, Wei Cheng, Qiang He, Xiaolong Xie · 2018
How to increase the connectivity of the whole network is a critical research issue while achieving full coverage in WSNs. In this paper, a novel paradigm of regular topology is proposed which adapts Cooperative Communication (CC) model with two-node cooperation to achieve K-connectivity and full coverage. Then we analyze the changes of sensor connectivity in square triangle and hexagon patterns with the increase of transmission power under two-node cooperation and one-node operation respectively. Numerical results show our proposed paradigm on regular topology could increase the connectivity of the whole network effectively, while achieving full coverage for WSNs.
