MTSP based solution for minimum mobile node number problem in sweep converge of wireless sensor network

Environment physical parameters about the energy efficiency status in building can be monitored with wireless sensor network with mobile node. To reduce the cost and complexity of wireless sensor network, sweep coverage for wireless sensor network with mobile node is defined in this paper. To minimize the number of mobile nodes in desired wireless sensor network, the problem for minimum number of mobile nodes and a fast solution based on MTSP for the problem are presented. In our experiment, the MTSP problem is solved with PSO algorithm. Experimental results show that the fast solution based on MTSP can work correctly and quickly.
