Data transmission is the most important issue in wireless sensor network (WSN). The energy consumption and latency are the key factors of data transmission. To optimize these factors, a noble data aggregation algorithm is proposed in this paper. The proposed algorithm is originated from LEACH, and energy efficiency and latency is considered as the researching parameters. The overlap of detect regions...
There are many routing protocols and algorithms developed for data transmission in Wireless Sensor Network (WSN). The main objective of this paper is an increasing of performance and reduction of energy dissipation in WSN. In this paper, the Bacterial Evolutionary Algorithm (BEA) or Bacteriologic Algorithm (BA) is selected to compare performance with Genetic Algorithm (GA) and Low Energy Adaptive...
A power-and-bandwidth efficient cooperative communications protocol where a sensor node assists two others for their data transmission to a clusterhead in WSNs (wireless sensor networks) using LEACH (low-energy adaptive clustering hierarchy) is proposed in this paper. Its closed-form BER expression which generalizes BER one for the decode-and-forward protocol (DF) is also derived. We proved that the...
