Sabari, A Preemptive Link State Spanning Tree Source Routing Scheme for Opportunistic Data Forwarding in MANET, Asian Journal of Information Technology, Volume 13,Issue 9, 2014, Pages 526-529, ISSN 1682-3915, ajit.2014.526.529, (https://makhillpublications.co/view-article.php?doi=ajit.2014.526.529) Abstract: Oppurtunistic Data Forwarding (ODF) has drawn much attention in mobile ad hoc networking research in recent years. The effectiveness of ODF in MANET depends on a suitable routing protocol which provides a powerful source routing services. PLSR is featured by source routing, loop free and small routing overhead. The update messages in PLSR are integrated into a tree structure and no need to time stamp routing updates which reduces the routing overhead.
