An improved broadcasting algorithm for underground wireless sensor network

For problem of high energy consumption of existing broadcasting algorithm for underground wireless sensor network, an improved forward broadcasting algorithm of wireless sensor network was proposed. In the algorithm, forwarding nodes select prioritized node to forward information according to their own positions, so as to decrease redundant forwarding information and reduce energy consumption of the network. The simulation results show that when network node density achieve certain value, the algorithm can satisfy network receiving rate requirement, and limit total forwarding information, so as to reduce energy consumption of wireless sensor network effectively.
