QPSO and FISH Algorithm Apply in the Wireless Sensor Network Coverage

The applying of QPSO-FISH algorithm in the wireless senor network are mainly studied in this paper. Wireless sensor network is an energy-constrain network, coverage efficiency and power consumption are two important performance indicators. Maximizing the network coverage and minimizing the number of working nodes are network optimization goals. Establish an optimal model for coverage in wireless sensor network. Utilize the characteristics of parallel, fast coveragence and fast local search speed, propose a coverage optimization strategy based on QPSO-FISH algorithm. The results of simulation show that the algorithm can get an optimal set of nodes and improve the real-time capability of nodes scheduling.
