A Fuzzy logic-based Energy Efficient Packet Loss Preventive Routing Protocol

The sensor nodes in a wireless sensor network (WSN) are typically characterized by limited power supply, low bandwidth, small memory sizes and limited energy, leading to a very demanding environment to provide security. In this paper, we propose a protocol named fuzzy logic-based energy efficient packet loss preventive routing protocol (FEEPRP) that adopts a routing algorithm which imparts security in terms of avoiding malicious nodes and prevent data loss as well as constrains the utilization of excess energy. FEEPRP does not absorb the idea of any kind of digital signatures or message authentication code (MAC) for authentication, as the latter produce high communication overhead. It exploits the fuzzy decision making model to avail an energy-efficient secure route to the destination. Simulation analysis shows that the FEEPRP helps to impart effective security to the network while maintaining an improved network performance level.
