| Summary: | 碩士 === 國立中正大學 === 通訊工程研究所 === 96 === Maintaining a dependable operation is a challenge task in a critical wireless sensor network that has unattended deployment and resource-constrained natures. Identifying potential solutions to the problem of sensor relocation is paramount when regular node intend to replace the failure nodes to keep the given system function. This paper introduces a novel technique, Continuation of Feasible Energy Algorithm (COFE), to relocate sensor locations without paying a high network lifetime penalty. The assessments of COFE are conducted on the MATLAB platform and show the effectiveness of network lifetime. The salient features of the proposed COFE include: (1). able to produce less network lifetime penalty for a complex wireless sensor network, and (2). capable of balancing response time with network lifetime. Such a technique can provide a key answer required for advancing the state-of-the-art in on-demand sensor deployments.
