Reactive, Proactive MANET Routing Protocol Comparison
Ad-hoc networking is a concept of computer communications is that the users wanting to communicate with each other form a temporary network, without any form of centralized administration. The purpose of a routing protocol is each node participating in the network acts both as host and a router and must be to forward packets for other nodes. An ad-hoc network has certain characteristics which imposes new demands on the routing protocol. The most important characteristic is the dynamic topology, which is a consequence of node mobility. Nodes can change position quite frequently, which means that the authors need a routing protocol that quickly adapts to topology changes.
