碩士 === 國立中央大學 === 電機工程研究所 === 98 === In wireless sensor networks to maximize sensing coverage is an important subject of discussion issues. Since sensor nodes are deployed randomly, energy depletion or failure, that cause to produce coverage hole area. In order to maintain the network connectivity and improve the sensing area of coverage region, many of the algorithms are proposed to solve related problems. Therefore, by simulation, performance analysis is obtained the relevant parameters and properties, and compares the advantages and drawbacks in algorithms. The NS2 is similar real network simulation tool, and the NS2 simulation environment is flexible to investigate how various protocols perform with different configurations and topologies. Therefore, in this paper, based on NS2 as the main simulation tool, we aim at the three different coverage hole area algorithms simulation separately, and observe each algorithm characteristic and difference.
