Octopus: A Scalable Position-based Routing Protocol for MANETs

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.
