A price-based interactive data queue management approach for delay-tolerant mobile sensor networks

This paper presents a price-based interactive data queue management approach (PI-DQM) for delay-tolerant mobile sensor networks (DT-MSNs) to address the priority deviation problem during the data transmission process. Three interactive parameters are introduced and weighted values α and the p-value are used in the price-based interaction model to identify the data priority. The method is transparent to prioritized data packets. Its effectiveness is illustrated by showing that it can ameliorate the data delivery ratio and achieve good performance in terms of average delay.
