چکیده
|
To improve the lifetime of mobile sink-based wireless sensor networks and considering that data transmission delay and hops are limited in actual system,a lifetime optimization algorithm limited by data transmission delay and hops (loa-dh) for mobile sink-based wireless sensor networks is proposed. in loa-dh,some constraints are analyzed,and an optimization model is proposed. maximum capacity path routing algorithm is used to calculate the energy consumption of communication. improved genetic algorithm which modifies individuals to meet all constraints is used to solve the optimization model. the optimal solution of sink node's sojourn grid centers and sojourn times which maximizes network lifetime is obtained. simulation results show that,in three node distribution scenes,loa-dh can find the movement solution of sink node which covers all sensor nodes. compared with mcp-rand,mcp-gmre,and easr,the solution improves network lifetime and reduces average amount of node discarded data and average energy consumption of nodes. © 2017 yourong chen et al.
