SEPFL routing protocol based on fuzzy logic control to extend the lifetime and throughput of the wireless sensor network

Abstract

In this paper a new protocol using fuzzy logic control has been proposed. The protocol is based on Stable Election Protocol (SEP). Fuzzy logic control based on three variables, distance of nodes form base station, density of nodes and the battery level of nodes along with the traditional threshold values used in SEP are used to enhance the process of cluster head election in the existing SEP protocol and improve the lifetime and throughput of the Wireless Sensor Network. The result of the simulation which has been done in MATLAB simulator indicates that Stable Election Protocol based on fuzzy logic is more energy efficient and improves the lifetime and throughput of the network by 73.2 and 68.54 % respectively comparing with the existing SEP protocol.

Distributed fuzzy approach to unequal clustering and routing algorithm for wireless sensor networks

“…This issue has been addressed in ECPF, where the tentative CHs are selected based on the residual energy of nodes and the final CHs are computed using fuzzy logic by considering the node degree and the node centrality as fuzzy input variables. The SEP‐FL is another fuzzy logic‐based clustering algorithm that considers battery level, distance to the BS, and the density along with a threshold value for CH selection.…”

“…To avoid such problem, some unequal clustering algorithms have been discussed in recent years. 8,[36][37][38][39][40][41][42][43] In these algorithms, the cluster size closer to the BS is kept smaller as compared with the clusters away from the BS. This ensures availability of more CHs closer to the BS to share the high data traffic load.…”

An Immune-Based Energy-Efficient Hierarchical Routing Protocol for Wireless Sensor Networks

“…The fitness function of GAECH considers the dissipated energy of in data collection of round, standard deviation of dissipated energy between clusters, CH dispersion and CHs energy consumption, in forming clusters. A Stable Election Protocol based on Fuzzy Logic (SEPFL) was designed in [17] to prolong the lifespan and throughput of WSNs. SEPFL utilizes the fuzzy logic control to enhance the CH selection and prolong the lifetime of the SEP protocol [18] depend on the distance of the sensor nodes from BS, the nodes density and the battery level of the sensor nodes.…”

“…The effect of the node heterogeneity on the performance of the IEERP protocol is studied in this simulation compared to the SEP [18] and the SEPFL [17] protocols. Simulation consists of 100 heterogeneous sensor nodes that are randomly distributed within a 100×100 field.…”

“…Thus, the IEERP improves the network throughput by 72.28 and 128.76 % as compared to the other two algorithms. [18] 1007 1500 2325 0.5669 SEPFL [17] 1194 …”
