Abstract
We present a Smart Antenna assisted GRAdient Broadcasting (SA-GRAB) data delivery protocol for large-scale WSN, where only the sink is equipped with a low-cost smart antenna offering a relative small coverage. SA-GRAB partitions the smart antenna's coverage into N inner sectors directly and the rest part of WSN into N outer sectors during the cost field building by means of a "dyeing" procedure. Once an event occurs, data are forwarded jointly by sector aware gradient broadcasting and direct communication with smart antenna. Simulations show that SA-GRAB achieves better energy-efficiency and scalability for large-scale WSN applications than prior work.
