An Optimized Directional Distribution Strategy of the Incentive Mechanism in SenseUtil-Based Participatory Sensing Environment

This paper proposed an optimized strategy of the incentive mechanism for participatory sensing network on the basis of Sense Util which is our previous research work. For optimizing, the strategy considered the possibility of that some users actually cannot participate the current sensing task, so in order to avoid unnecessary energy and bandwidth consumption on server end, users were classified into different subsets according to their position, and server distributed the sensing tasks directionally. To evaluate the performance of the strategy, we conducted simulation study, and the results showed that the optimization work is energy efficient.
