A Strategy of Deploying Constant Number Relay Node for Wireless Sensor Network
intelligent data analysis(2018)
摘要
The wide application of wireless sensor network facilitates a great variety of utilizations including remote monitoring, air condition evaluating, tracking and targeting, and so on. However, the performance of a wireless network is constraint by low-power and low-capacity. Hence, long-distance communication is not available for a homogeneous network, which hinders the growth of wireless network. This work proposed a strategy for deploying Relay nodes into the network based on directional shuffle frog leaping algorithm. The Relay node is an advanced node which is more powerful than common node and it can decrease the workload of inner nodes and improve the transmission situation of outer nodes. The experiment simulates other two algorithms as the comparison tests. The performance is good as evidenced by the experiment results of common nodes coverage, connectivity of Relay nodes and the fitness value.
