Energy-saving Hybrid Network Integrating WSNs and Crowd Sensing

The main contribution of the whole work proposes a hybrid network method integrating WSNs and crowd sensing, establishes a hybrid model and designs the hybrid mechanism. To solve the high cost, low coverage and inflexible expansion of traditional wireless sensor network, the crowd sensing technology is introduced in WSNs. The maximum network life cycle and minimizing energy utilization is derived on the basis of truncated power-law working principle of hybrid mechanism. Simulation results show that hybrid network can effectively save energy and prolong network lifetime.
