Abstract

Wireless Sensor Networks (WSN) are set of energy-limited sensors, which recently have been point of interest due to their vast applications. One of the efficient ways to consume energy in these networks is to utilize optimal routing protocols. In this approach, we proposed a greedy hierarchical chain-based routing method, named, PGC (stands for Persian Greedy Chain) which route the network applying Spread Spectrum codes as a mask given to the grid cells. Due to similarities between the proposed method in this article and LEACH protocol, we compare this routing protocol with the proposed model from diverse aspects in the simulation section such as remaining energy and being fault tolerant and reliable. The results prove that presented method is more robust and efficient.
