Performance Study of Adhoc on-Demand Link Quality Aware Route Search Protocol (AO-LQARSP)

Abstract — A Wireless Sensor Network (WSN) is a network with few tens to thousands of small devices called sensor nodes which are connected wirelessly and involve in communicating the data. WSNs have generated tremendous interest among researchers in recent years because of its potential usage in wide variety of applications. The sensor nodes in WSNs have scarce power; they work in harsh and unattended environments which initiates the need for a better and more reliable routing path to send data. In this paper a routing protocol is proposed to select the route based on better signal strength conditions using Link Quality Indicator of the received signal for IEEE 802.15.4 standard. The performance of the proposed routing protocol is compared with standard reactive routing protocol Adhoc On-demand Distance Vector (AODV) with metrics like total packets received, throughput, total bytes received, average end-to-end delay and average jitter and total energy consumed for various node density scenarios
