Abstract

Time-critical applications of Wireless Sensor Networks (WSNs) demand timely data delivery for fast identification of out-of-ordinary situations and fast and reliable delivery of notification and warning messages. Due to the low reliable links in WSNs, achieving real-time guarantees and providing reliable data is quite challenging. To ensure data reliability, traditionally various retransmission mechanisms have been used, which in turn introduce extra delay. In this paper, we propose READ, i.e., a reliable and realtime aggregation-aware data dissemination to ensure reliable and fast data delivery in a chain-based WSN. We also investigate the relatively unexplored topic of impact analysis of Time To Live (TTL) and link reliability parameters on network performance in terms of attained hit ratio for three different approaches, i.e., READ, QoS-ACA, and the stop-andwait (S-W) ARQ to assess the appropriateness of each method facing different conditions. The simulation results show READ performs better in terms of hit ratio compared with QoS-ACA and S-W ARQ when link reliability is low and packet's TTL is short. Although not being the primary goal of READ, energy consumption of the protocol is also much lower than the other two approaches.
