Abstract:
One of the major issues in current routing protocols for mobile ad-hoc networks (MANETs) is to
develop a routing protocol that can satisfy different applications’ needs and optimize routing paths to
cope with the scalability of the networks.
In this document, we present the recent work in the field of position-based routing protocols and
compare between them depending on network overhead, scalability, end-to-end delay, and routing
strategy metrics.
After that, a new scalable position-based routing protocol called Octopus has been proposed to be
used in MANETs. Octopus uses restricted directional flooding to reduce the number of packets sent
over the network. The performance of Octopus has been studied using NS2 simulator. We show by
detailed simulation that our proposed protocol reduces the packets routing load, bytes routing load,
packet loss ratio, route acquisition latency, end-to-end delay and increasing the network scalability
compared to LAR routing protocol.
Keywords: Ad-Hoc networks, MANET, routing protocols in MANETs, position-based routing.
