A Technique to Improve the Lifetime of Heterogeneous Wireless Sensor Networks by Removing Redundant Packets

A Wireless Sensor Network is an infrastructure-free wireless network that uses an ad-hoc deployment of a large number of wireless sensors to monitor system, physical, and environmental factors. Sensor node energy consumption is a major determinant of wireless sensor network longevity. The Distributed Energy-aware Fuzzy Logic-based routing algorithm (DEFL) proposed in this paper aims to strike a compromise between energy efficiency measures balance. For the shortest path calculation, our architecture captures the network state using relevant energy measurements and maps them to cost values. I also added a Redundant Packet Monitoring Algorithm to each sensor node as a recommended technique, which attaches temporary memory to each sensor node and checks it anytime the sensor node senses any data.
