1. EIDA: An Energy-Intrusion aware Data Aggregation Technique for Wireless Sensor Networks

Nafiseh Daneshgar; M. Habibi Najafi; Mohsen Jahanshahi; Ehsan Ahvar

Volume 2, Issue 1 , Winter 2016, Pages 1-8

Abstract
  Energy consumption is considered as a critical issue in wireless sensor networks (WSNs). Batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. An efcient solution to improve energy consumption and even trafc in WSNs is Data Aggregation ...  Read More
