Research on the Optimal Design of Repeaters for WSNs Based on CTCSS

Recently, the speed of development and application domain technology of the wireless communication have already surpassed the fixed service technology. Repeater is the critical role in the message transmission. Thus, how to minimize the number of repeaters and meanwhile serves a certain number of users with limited resource is an important issue. This paper is constructed to solve the related issue in this paper. To discuss the repeaters coverage, the cellular network is to discover the best partition solution with the least overlap coverage and seamless. To consider the number of users and to design the full network coverage solution, a Hamilton circuit with relevant requirements which transmits every hexagon’s repeaters has been searched and frequency band of every hexagon has been found by improved backtracking algorithm.
