EE-LEACH: development of energy-efficient LEACH Protocol for data gathering in WSN

Abstract

A wireless sensor network (WSN) consists of a huge number of sensor nodes that are inadequate in energy, storage and processing power. One of the major tasks of the sensor nodes is the collection of data and forwarding the gathered data to the base station (BS). Hence, the network lifetime becomes the major criteria for effective design of the data gathering schemes in WSN. In this paper, an energy-efficient LEACH (EE-LEACH) Protocol for data gathering is introduced. It offers an energy-efficient routing in WSN based on the effective data ensemble and optimal clustering. In this system, a cluster head is elected for each clusters to minimize the energy dissipation of the sensor nodes and to optimize the resource utilization. The energy-efficient routing can be obtained by nodes which have the maximum residual energy. Hence, the highest residual energy nodes are selected to forward the data to BS. It helps to provide better packet delivery ratio with lesser energy utilization. The experimental results shows that the proposed EE-LEACH yields better performance than the existing energy-balanced routing protocol (EBRP) and LEACH Protocol in terms of better packet delivery ratio, lesser end-to-end delay and energy consumption. It is obviously proves that the proposed EE-LEACH can improve the network lifetime.

Energy Efficient Fault Tolerable Routing Protocol for Wireless Sensor Networks

“…Fig. 3 shows the simulation result for n = 100, initial energy of a node is 2J, base station placed at (110m, 45m) and packet length is 4000 bits for this simulation [9]. Fig.…”

“…3 shows that the total energy required for network operation is also almost constant over time. The proposed EEFT has less energy consumption than EE-LEACH protocol [9] because of better faults tolerance. Fig.…”

“…In this section the performance of the proposed EEFT technique is evaluated and compared with the existing distributed cluster head scheduling EE-LEACH [9] and FTREEP [12] Protocol. There are 100 sensor nodes deployed in the 100 100 m 2 area.…”

An Optimized QoS-based Multipath Routing Protocol for Wireless Sensor Networks

“…By using multipath cluster head routing based on the credit value ensures a high quality route and prolong the lifespan. Arumugam et al, [14] have introduced an Energy-Efficient Low Energy Adaptive Clustering Hierarchy (EE-LEACH) protocol, which improved the lifespan and data ensemble of the network. The coverage probability is derived with respect to the Gaussian distribution.…”
