Proactive Routing Protocol in Mobile Ad Hoc Networks Using Path Finding Techniques
Mobile Ad hoc NETwork (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central administration. Moreover, every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. There are several familiar routing protocols like DSDV, AODV, DSR, etc. which have been proposed for providing communication among all the nodes in the network. In this paper, a new proactive source routing protocol incorporating a tree based software structure is proposed. In this paper, the authors propose a lightweight Proactive Source Routing (PSR) protocol. PSR can maintain more network topology information than Distance Vector (DV) routing to facilitate source routing, although it has much smaller overhead than traditional DV-based protocols [e.g., Destination-Sequenced DV (DSDV), Link State (LS) based routing (e.g., Optimized Link State Routing (OLSR)) and reactive source routing [e.g., Dynamic Source Routing (DSR)].
