A Novel Routing Technique for Asymmetric Links: ProHet
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 2
Abstract
To design efficient, reliable and scalable routing protocols in wireless heterogeneous sensor networks with asymmetric link is a challenging task. Usually most protocols in sensor networks work with high overhead.In this paper, we propose a novel routing technique for asymmetric links(ProHet) in Wirelesss Heterogeneous Sensor Network.It utilizes asymmetric links to attain assured delivery rate and it also provides low overhead. The protocol first produces bidirectional routing path for asymmetric link and uses a probabilistic strategy to choose the forwarding nodes then, sending messages and getting back acknowledgement . Extensive Simulation are conducted using MATLAB to verify its efficiency and performance.
