Abstract: In this work, we investigate the partial sensing coverage with connectivity problem in structured lattice wireless sensor networks (WSNs) through mathematically modelling, theoretical derivation, computer-based simulations, and performance evaluation. Two popular patterns (square and equilateral triangle) are considered. We found: 1) a noticeable amount of sensors can be saved in lattice WSNs if a small percentage of application-tolerable sensing coverage is sacrificed; 2) there exists a threshold partial sensing coverage, π/4, belowwhich both square and triangle patterns require the same amount of sensors, above which the triangle pattern is superior; 3) deployment pattern impacts the network detectability and 15.47% more sensors are required to guarantee the worst-case detectability in a triangular lattice WSN; and 4) there exists a critical ratio of communication range to sensing range in employing partial sensing coverage to trade for deployment efficiency. Simulation outcomes are shown to validate the analysis.
