Abstract:

A minimum-cost-deployment strategy based on objective optimization is proposed to address the problems existing in heterogeneous sensor networks such as high density of the nodes,bad target coverage and connectivity performances,and high deployment spending.The problem we aim to solve is characterized by different parameters in terms of the deployment cost of positions and the cost of the sensors.The enhanced version of coral reef optimization (CRO for short) algorithm is utilized to solve the problem of how to select the proper positions and sensors to achieve the minimum deployment cost of heterogeneous sensor networks which can fulfill both k-coverage and m-connectivity requirements.The enhanced version of the CRO is named ECRO.In the ECRO two methods are employed to improve the optimization efficiency of the CRO.One method is that inspired by the process of the harmony search algorithm the operators such as HMCR and PAR of the harmony search algorithm blend with the CRO.The other one is that the excellent solutions are reused to exploit the knowledge and experience accumulated in the process of running the CRO.For comparison purposes,a greedy algorithm is also proposed.Simulation experiments show that compared with some related existing algorithms,the proposed algorithm reduces the deployment cost of sensor nodes while fulfilling the requirements of k-coverage and m-connectivity requirements.

Key words: wireless sensor networks, heterogeneous networks, connected coverage, coral reef optimization algorithm, harmony search algorithm
