A Novel Adaptive Congestion Avoidance Protocol for Wireless Sensor Networks

Abstract

Most researches on wireless sensor networks (WSNs) are focused on how to save the energy of the sensor nodes. However, in some applications of WSNs, such as in the monitoring of an earthquake or a forest fire, it is much more important to transmit emergency data packets to the sink node as soon as possible than to save power. This paper proposes a novel Adaptive Congestion Avoidance Protocol (ACAP) model to provide a feasible WSNs architecture that will save the energy of the sensor nodes in the normal situation, but will transmit emergency data packets in an efficient manner to the sink node. The simulation analysis shows that the ACAP provides superior performance during both normal and emergency conditions. DOI: http://dx.doi.org/10.11591/telkomnika.v11i12.371
