Abstract
Wireless sensor networks (WSN) are the subject of the era due to its importance and wide
applications. The last decade of research focused on how to improve its performance in
terms of enlarging lifetime and better handling network dynamics. Many WSN applications
such as monitoring and reporting are time critical so, the performance of WSN can not
include lifetime only, but also other performance measures such as delay must be taken into
consideration as well. This paper focuses on the WSN network layer which includes routing
techniques as a main key in high performance applications. A routing technique based on
virtual rings and genetic algorithm is proposed to shorten the round delay time. This
technique uses virtual ring features in addition to clustering methods to divide the sensors in
the network into groups contain nearby sensors. The main advantage of this proposed
technique is that it maximizes the interval of the first node failure besides obtaining a
reasonable delay in forwarding data to sink through the usage of the virtual rings.
